What Are The Primary Signs And Symptoms Of A Brain Tumour?

This March marks the 21st anniversary of Brain Tumour Awareness Month, and every radiotherapy centre plays a part in ensuring that as many brain tumours are treated as possible, with advanced technology and diagnostics assisting with this aim.

Initially launched by a group of brain tumour charities that would later form Brain Tumour Research, Brain Tumour Awareness Month focuses on fundraising for the treatment and prevention of brain tumours, as well as supporting people who are undergoing treatment.

As well as this, one major goal of Brain Tumour Awareness month is to ensure that people are aware of major common signs and symptoms that could be caused by a brain tumour, so that people can book an MRI or CT scan as soon as possible.

The symptoms of a brain tumour can vary somewhat depending on the type of tumour, its grade, its position in the brain and which parts of the brain it is affecting.

Headaches

Whilst a symptom of several conditions, including tension, stress or fever, a headache which feels different from normal can be a symptom of a brain tumour, especially if they do not seem to go away.

Headaches are caused by raised intracranial pressure, where the tumour pushes against the skull. This can cause not only headaches that tend to be dull, constant and do not go away, but also nausea and eyesight changes such as double or blurred vision.

They are also often more noticeable in the morning, and if this is the case, then an appointment with a doctor should be booked so that tests can be arranged.

Sickness And Drowsiness

Similar to headaches, there are a range of conditions which have nausea, vomiting and drowsiness as potential causes, but as noted above, they can be a symptom of raised intracranial pressure.

If other common causes such as food poisoning, alcohol, dehydration, pregnancy or common conditions such as the flu can be ruled out, if the nausea does not show any signs of improvement even after vomiting, and is accompanied by headaches and vision changes, it could be a symptom of a brain tumour.

Many common brain tumour symptoms are accompanied by others and persist, which means that they should be examined if there is no sign of potential improvement.

Abnormal Vision Changes

Most people will experience some form of gradual vision change over their lives, but a sudden change in vision may need to be examined by an ophthalmologist in order to rule out other potential causes.

Brain tumours can increase pressure on the optic disc and optic nerve, both of which can cause blurred vision, double vision, sudden temporary loss of vision or a loss of peripheral vision, causing objects to suddenly appear.

Exactly how vision is affected will depend significantly on where a tumour is located, and it is important to explain these symptoms to a doctor, book an eye test or go to hospital if these symptoms are severe and sudden in appearance.

Personality Changes

Some symptoms are first noticed by close friends and family, such as changes in personality or behaviour.

These can vary from person to person but can include increased forgetfulness, irritability, anxiety, depression, mood swings or a loss of inhibitions.

This tends to be caused by brain tumours that affect the frontal lobe, which manages emotional regulation and understanding the emotions of other people.

As with headaches, not all changes in personality can be attributed to brain tumours, with stress, tension or personal life events all contributing to behavioural change. However, any sudden personality or behavioural changes should be examined.

It can be useful for the person or someone close to them to document any personality changes and how this differs from their usual behaviour.

Seizures

A common symptom of brain tumours is seizures or epilepsy, a common pattern of seizures. According to the Brain Tumour Charity, two-thirds of people diagnosed with a brain tumour will experience at least one seizure caused by their tumour.

Seizures themselves have varying symptoms, from uncontrollable jerking motions (often known as fits), stiffness, losing awareness, unusual sensations or collapsing. In some cases, the person is not aware that they are having a seizure.

Seizures and epilepsy will typically require a visit to a specialist, as epileptic fits can be potentially life-threatening depending on where they occur, and part of this process is determining any potential causes and treatment paths for stopping or reducing the severity of seizures.

Alongside radiotherapy, a specialist may prescribe anti-convulsant drugs to control the seizures as part of the overall treatment.

What Can You Do To Feel Better During Cancer Treatment?

Cancer treatment is a process with many steps before, during and after visiting the radiotherapy centre, and specialist cancer doctors and nurses will take a holistic, conscientious approach during the entire duration of the journey.

Every cancer diagnosis and treatment is different, which means that there will be aspects of one person’s cancer journey that will be different from someone else’s. This means different types of treatment and different challenges before, during and after.

As both physical and mental health can have an effect on treatment according to at least one study, a key part of treatment is remaining positive, active and motivated with help from yourcare team and support network.

Whilst every cancer journey is unique, here are some examples of small, simple steps you can take to help reduce mental and physical stress whilst undergoing cancer treatment.

Seek Help Through Your Support Network

You never have to face cancer alone, and there are so many people in your life, in your care team, or who are or have been in a similar position to you who will help you with anything you need.

A problem shared is also halved, and soon after a diagnosis, a helpful step is to identify who you want to be part of your social network and what you might need whilst going through treatment.

Friends, family, coworkers and loved ones will be there for you to go to your regular appointments, help with errands during days when cancer fatigue means you have less energythan you would otherwise and be a sympathetic ear.

Your care team will also be there for you to provide advice and information regarding aspects of the treatment and taking care of yourself throughout your cancer journey.

Finally, there are support groups that are often available in your local community which can bring you closer to people who are being treated for cancer as well, which can provide an opportunity to discuss aspects of treatment and make new friends in the process.

Similarly, a professional therapist or counsellor can also help by providing a safe, judgement-free place to process everything, as well as provide a toolkit of techniques to help you manage the more difficult parts of treatment.

Eat A Nutrient-Dense Diet

A balanced diet is an essential part of a healthy lifestyle, but it is especially important during cancer treatment, where maintaining energy levels and boosting strength is exceptionally important.

As every cancer treatment is unique, so too are everyone’s dietary needs during treatment. You will be offered a nutritionist who can devise a personalised nutrition plan that suits your needs best based on the overall treatment plan, the expected effects of treatment and any personal dietary needs.

In general, any recommended diet for a healthy lifestyle that could reduce the risk of health complications is generally going to be beneficial when going through cancer treatment, and many doctors will use the basic principles of the Mediterranean diet as a template for advice.

Focusing on eating less processed meat, more lean protein, more fruits and vegetables as well as healthy fats such as nuts, seeds and olive oil can provide some benefits. Nutrient-rich smoothies and soups can be helpful as they are often easier to digest.

As with any dietary change, ask your cancer team if you have any questions or would like any further recommendations.

Stay Active

Exercising is not only possible during most types of cancer treatments but it can provide significant mental and physical benefits.

Any extra exercise you do will provide significant benefits according to research compiled by Cancer Research UK, including improving your mood, giving you more energy and helping you stay mobile.

Everyone has different fitness goals and needs, so focus on what you can do and listen to your body. There are different types of exercise to suit every person, and a physiotherapist will often be a part of your cancer team to help you find a routine that works for you and that you can maintain.

Give Yourself Time And Space

In a particularly hectic world, the time we take to stop, breathe and relax is an essential part of a healthy lifestyle for both psychological and physiological reasons.

Deep breathing, meditation and yoga help slow the heart rate, control breathing and help people to feel more at ease, something that can be essential during particularly stressful situations.

Mindfulness practices, such as breathing exercises, meditation and journaling can help people during cancer treatment by providing a way to reduce or relieve stress gradually over time.

5 Important Facts About Trigeminal Neuralgia Treatment

There are certain conditions which can be effectively managed and treated once their causes are understood, and trigeminal neuralgia is a particularly illustrative example of this.

Once it has been diagnosed and a patient has been referred to a radiotherapy centre for treatment, several pathways are available determined by a patient’s medical history and the cause of pain.

As understanding is important to the treatment and management of the condition, here are some facts about trigeminal neuralgia that are important to know.

A Dentist Will Often Notice Symptoms First

The facial pain caused by trigeminal neuralgia is often felt in the gums, jaw and teeth, which usually means that it will be a dentist who will be the first person that many patients see when seeking treatment for the condition.

They can rule out that it is a toothache, abscess, or other dental concern through the use of an X-ray or dental CT scan, before suggesting that the patient sees their GP, who will themselves help to rule out other conditions that could cause similar pain sensations.

Once other causes are ruled out, a GP will refer the patient to a specialist or the patient will seek out a second opinion.

It Was First Discovered Three Centuries Ago

Trigeminal neuralgia is sometimes known as Fothergill disease, named after the doctor who first discovered the condition, John Fothergill.

In 1773, Dr Fothergill provided the first complete and accurate description of the condition, and would also describe conditions such as angina, diphtheria and streptococcal sore throat in English for the first time.

Nearly a century later, another doctor for the University of Edinburgh, John Murray Cornochan, would be the first person to successfully treat trigeminal neuralgia, through a surgical procedure to remove the trigeminal nerve.

There Are Three Main Types Of Trigeminal Neuralgia

Trigeminal neuralgia cases are grouped into three categories depending on the cause.

The first, and most common of these, is known as classical trigeminal neuralgia, which is caused by pressure on the trigeminal nerve which makes it activate and causes the facial pain that is characteristic of the disorder.

If the trigeminal neuralgia symptoms are caused by another medical condition, such as a tumour, multiple sclerosis or injury to the face, it is categorised as secondary trigeminal neuralgia.

Finally, if the cause is unknown, it is categorised as idiopathic trigeminal neuralgia, and until a cause is determined, treatment is centred around pain management.

MRI Scans Can Find The Cause

In most cases, a diagnosis is confirmed through a magnetic resource imaging (MRI) scan, which uses a series of magnetic fields to create a detailed internal image of the face.

It can be used to find pressure on the trigeminal nerve, its location and the precise cause. This can be used to diagnose a patient’s symptoms as trigeminal neuralgia and is typically used to help plan treatment.

It Does Not Always Require Surgery To Treat

There are three main treatment paths, depending on the cause and how well a patient has responded to other treatments.

Initially, anticonvulsant medication is the first treatment many people with trigeminal neuralgia are likely to take.

Many over-the-counter painkillers are not effective at treating the specific cause of pain seen with trigeminal neuralgia, so regular doses of an anticonvulsant medication such as carbamazepine will be initially taken to slow down nerve impulses and stop the trigeminal nerve from activating.

Alternative medicines are available if carbamazepine does not work, but specialist surgery can also be offered which can provide relief for months, and sometimes years.

This includes microvascular decompression, which helps relieve pressure on the trigeminal nerve and can therefore provide long-term pain relief.

These also include keyhole surgical treatments undertaken under general anaesthetic which aim to deactivate the nerve entirely, but an alternative to this that specialists are using to treat trigeminal neuralgia without the need for surgery is stereotactic radiosurgery.

Treatments such as Gamma Knife work by using multiple beams of radiation concentrated to a point to provide precise doses of radiation to damage the trigeminal nerve where it enters the brainstem.

It works through the use of a complex frame which holds your head in place and is used to guide the beams of radiation to the central point where the nerve needs to be damaged in order to stop activating.

It requires no incision, no general anaesthetic (although local anaesthetic is often provided for the points where the frame is secured), and does not require a stay in the hospital once the procedure is completed.

It can sometimes take time for the procedure to take effect, but it can provide relief for years.

What Were The Early Treatments That Inspired Radiotherapy?

Anyone who is prescribed a course of radiotherapy treatments from a specialist centre can feel comforted that they are receiving a proven treatment that is over a century old and is still evolving and improving in its efficacy.

From the very start of radiotherapy’s development as a potential treatment for cancer, the effectiveness of radiation was never in doubt, because the underlying therapeutic principle largely predates the discovery of radiation itself.

Replacing Chemicals And Electricity

The therapeutic action of radiotherapy is to burn away the tissue that is exposed to radiation, which means that its targeted use can effectively destroy unwanted cells.

The main developments from this discovery in 1896 by Leopold Freund, Eduard Schiff, Emil Grubbe and Victor Despeignes paved the way for progressively better targeted, safer and more effective forms of treatment.

However, the underlying therapeutic action was much older than this, even if the tools used to destroy the malignant tissue were far less accurate and far more dangerous.

Early 1800s: Electrotherapy

One main form of treatment which inspired the development of radiotherapy once radiation was discovered was electrotherapy.

Unlike modern electrotherapy, which tends to use small electrical currents to stimulate recovery or enhance the effects of certain chemotherapy treatments, the field of electrotherapy up until the early 19th century was rather more experimental.

Up until Golding Bird, who helped rehabilitate the field of electrotherapy in the same way that Henri Coutard would radiotherapy in the 1930s, electrotherapy was another treatment that was often extremely dangerous with somewhat dubious benefits.

It was used to stimulate skin tissue and potentially burn away unwanted cancerous cells, and this method of action still sees some use today in the treatment of varicose veins.

Early 1900s: Escharotics

One of the earliest forms of treatment for killing unwanted tissue was poisonous and caustic substances called escharotics. However, these substances are not only extremely dangerous, scarring and in some cases outright mutilating, they can cause permanent, potentially life-threatening damage.

They were popular in early medical practice up until the early 1900s because, without the knowledge of how tumours survive, the tumour did appear to be burned away, along with a significant chunk of healthy tissue, making it appear to be effective even if the tumour very often grew back.

Escharotics have been largely discredited by mainstream medical practice since, and many of the substances used are illegal to sell because of the significant amounts of damage they can cause.

Even the few forms of cancer that can be treated topically such as basal cell carcinoma are typically treated with less damaging and more effective topical solutions than caustic chemical burns.

1896: Discovery of radiation

As early as 1896, doctors knew that radiation could provide the same ablative effect, even if they did not quite understand why.

Victor Despeignes accidentally discovered the therapeutic effects of radiotherapy when trying to treat a patient with late-stage stomach cancer.

Whilst he ultimately did not survive and Mr Despeignes only opted for radiotherapy under the mistaken belief that cancer was caused by parasites, it inadvertently proved a principle that would be more effectively demonstrated by Mr Freund and Mr Schiff, and mark a seismic shift in the history of medicine.

1933: Stereotactic frame & electrotherapy

Interestingly, the first use of the stereotactic frame to treat a human patient involved electrotherapy.

In 1933, Martin Kirschner published a paper wherein he detailed his use of a treatment for trigeminal neuralgia by using a stereotactic frame to make an incision large enough to feed an electrode to the trigeminal nerve, burning it away and reducing the pain.

1940s: Gamma Knife development

This principle would later be used by Lars Leksell for his innovative Gamma Knife radiosurgery and serves to highlight just how influential pre-radiation radiotherapy treatments were and how similar their core method of action is.

The main difference, of course, is a matter of scale, effect and invasiveness to a patient.

Surgery was and remains very effective but is also extremely invasive and typically requires a patient to spend several nights in the hospital to recover.

Escharotics may not require incisions but they are invasive and require time to recover from the intense and often unpredictable damage that the materials could cause. This lack of consistency is what led to them being almost universally outlawed.

Electrotherapy was less invasive but in some cases still required an actual incision to provide the same effect of ablation and burning away of unwanted or harmful tissue.

2025: AI in radiotherapy

In early January 2025, researchers explored the potential of using AI to make what had become an already accurate set of treatments even more precise, something that has some benefits for brain lesions and tumours but can be even more important for treating cancers that affect the digestive and reproductive systems.

How Prostate Cancer Treatment Has Advanced In Recent Years

Prostate cancer is a disease that kills millions of men every year. It is one of the most common forms of cancer and men will increasingly become vulnerable to it after the age of 50. Those who are overweight, have a family history of the disease or who belong to particular ethnic groups are at higher risk, with black men facing the greatest peril.

Even without being in a high-risk group, men should get themselves checked out if they suspect something is wrong, due to issues like erectile dysfunction, urinary problems, blood in semen or unexpected weight loss.

Improving Diagnostics

As with all cancers, early diagnosis increases the chances of beating the disease. Indeed, there has been some good news on this front, with the UK-based University of East Anglia claiming a breakthrough in developing a test to show if the prostate cancer is benign (as the majority are) or aggressive, something the current blood test cannot do.

It works through a urine testing kit that can be delivered to homes and taken there, before being posted back to the lab. The contents of the test can now reveal a wide range of results, including clues that show that the patient should go for further testing.

Professor Colin Cooper, who headed up the team that developed the test, remarked: “It’s astonishingly exciting – this is potentially a game-changer both for the initial assessment for prostate cancer, and people who have been diagnosed.”

What this highlights is the reality that diagnostics have been a weak point in prostate cancer treatment up until now, which means fewer men get the diagnosis they need until the cancer is more advanced.

In some cases, that means the treatment and the path to beating the disease is longer and more gruelling than it might otherwise have been, while in others the best that can be achieved is to extend life rather than save it.

Radiotherapy And Other Treatments

Our radiotherapy centre treats many patients with the condition, helping fight the cancer effectively. However, the success of this may depend on how early diagnosis takes place.

The good news is that it is not just the ability to diagnose aggressive cancers that is improving. The range of treatments and the capacity to apply them in the most effective way has grown markedly in recent years. As an article in Indian website News X notes, there have been several major developments in recent years aiding survival rates.

Some of this includes other treatments that can complement radiotherapy, such as PARP inhibitors, which block the enzyme that helps cancer cells repair their DNA after it has been damaged by radiotherapy or other treatments. This can be critical in the success of radiotherapy, with advancements in this area proving invaluable.

Others work in their own way, such as hormone therapy, which has been around for many years and helps reduce the production of hormones that promote the growth of cancerous cells. In recent years new therapies have become more effective at this.

Immunotherapies also have a role to play, but some of the most exciting developments come in areas that enhance the effectiveness of radiotherapy in destroying cancerous cells. This includes radiogland therapy, which specifically targets PMSA a protein found on the surface of prostate cells, enabling the radiation to be aimed directly at tumours.

All this can be added to the effectiveness of improved scanning technology for early diagnosis. The University of East Anglia breakthrough could be a further step forward in this crucial area, but already there are other promising advancements, like the use of artificial intelligence to identify problems a radiographer might not be able to spot so easily.

Could Vaccines Offer A Future Hope?

Some have even talked about the potential of vaccines to help tackle the disease. Various possible kinds could achieve effective results in preventing prostate cancer from taking hold in the first place: peptide, nucleic acid, viral, cellular and dendric cell vaccines are all the subject of research.

Should any of these prove truly effective, it may be that one day the way prostate cancer is treated can be completely different, with a greater focus on prevention in much the way that the HPV vaccine can protect women against cervical cancer.

However, unless and until such vaccines are fully developed and proven to be effective, other treatments will still be needed for patients who have prostate cancer and are either seeking to beat the disease outright or at least extend their lives.

Radiotherapy will remain a crucial weapon in the armoury for the foreseeable future, working alongside an array of other treatments.

Why Does Stereotactic Radiosurgery Primarily Treat The Brain?

If someone is prescribed a treatment plan that consists of stereotactic radiosurgery, they can enter the radiotherapy centre confident that they are being treated by one of the most effective, accurate and oldest radiosurgical treatments available.

The principle of stereotactic radiosurgery, as pioneered by Lars Leksell’s Gamma Knife in the late 1940s, is that multiple small beams of radiation that converge on a particular point can have a much greater effect without damaging the surrounding tissue and minimising overall exposure.

This treatment, whilst adjusted and refined over the past half-century, has been consistently used and effective even before there were effective ways to map treatments using MRI and CT scans. 

This naturally leads to a big question; if the Gamma Knife is so effective, why has the stereotactic principle not been widely applied to other forms of radiotherapy treatment outside of the brain and spine?

The answer is complex and one that medical researchers are doing their utmost to try and change.

The Sea Of Life

The almost tautological answer for why the Gamma Knife specifically is not used to treat other parts of the body is that it was only designed for the brain and relies on a very specific set of medical apparatus that has only been used in the head and cannot be used anywhere else.

Part of this is that the frame system that keeps the head in place for a Gamma Knife treatment is based on the Horsley-Clarke frame initially used to create an atlas of various animal brains before being applied to the human head over the course of four decades.

This tool, albeit heavily modified by Mr Leksell and others, is as fundamental and vital to the success of Gamma Knife as the source of radiation itself. This is why the treatment was tested and used before the widespread availability of three-dimensional medical imaging.

It meant that thanks to some rather complex mapping, a series of skull X-rays could be triangulated to position the stereotactic beams in order to treat patients effectively. Once CT scans and MRIs came in, this only made the process even more accurate.

A lot of this can be credited to Mr Leksell’s work himself, who famously said there was no tool too accurate for use on the brain, but whilst an accurate approach is mandatory for obvious reasons, it is also, relatively speaking, easier to achieve.

The skull helps keep everything in place and there is less variation, relatively speaking, with tumour and lesion positions, allowing for consistency and greater accuracy. 

Pair this with the stereotactic frame keeping the head from moving during treatments and it is perhaps understandable how the Gamma Knife started as a highly effective targeted treatment and has only gotten more accurate with time.

By contrast, the rest of the body is far less consistent and mobile. Organs are constantly moving in the body, not just in terms of pulsing, contracting and relaxing, but also shifting positions based on the position of the body.

Organs change shape depending on their use, muscles such as the diaphragm affect their shape, and even posture and the way people lie down can alter the shape, size and position of organs, particularly those in the abdomen.

This is a major problem when planning radiotherapy because the act of breathing creates a moving target that affects treatments, often requiring wider beams and more collateral damage to healthy tissue to ensure that all cancerous cells are destroyed.

There are ways to mitigate some of these issues, such as through the use of frames and casts to at least keep a body part securely in place during treatment, but there are a lot more variations than there are for the brain, requiring not only different treatments but a different treatment philosophy.

There have been attempts to change this over the years, primarily through increasing the speed at which medical images are produced and interpreted, and this could lead to Gamma Knife-like treatments becoming possible with that level of accuracy in the future.

In order for this to be accomplished, however, there needs to be a close to real-time form of three-dimensional imaging of body parts that can be used to plan treatments the same day they are executed, as unlike the brain there is the potential for much greater organ movement.

This concept, known broadly as real-time adaptive radiotherapy, is one that is at least conceptually possible, but it requires a widely-used real-time imaging system that, as of 2024 at least, has not been widely used.

Who Was The First Person To Be Treated With The Gamma Knife?

Precision is key when it comes to any treatment related to the brain, and part of the reason why people are often prescribed a trip to a radiotherapy centre for stereotactic radiosurgery is precisely because of this precision.

Lars Leksell once noted that no tool can be too refined for the human brain, and this became the motivation for him, alongside a desire for bloodless neurosurgery, to develop what became the Gamma Knife, the first-ever stereotactic radiosurgery technique and still one of the most widely used in the world.

It is a critical piece of equipment that has helped to ease the suffering of countless people and help treat many different types of brain cancer. However, who was the first to receive treatment using this pioneering technique? 

It depends somewhat on the definition of stereotactic radiosurgery.

Stereotactic Surgery With Radiation

In 1947, Mr Leksell started to develop the stereotactic frame, the critical part of the Gamma Knife technique.

However, the infamous perfectionist was initially wary about exactly what type of surgical system he would use. Radiotherapy was widely used by the end of the Second World War to treat other forms of cancer, but in the absence of MRI or CT scanners, the techniques involved were far less precise.

Mr Leksell would never have allowed that regardless, but he also was acutely aware that the distribution technologies for radiation therapy that existed at the time were perhaps not precise enough for the systems he had devised, meaning that the first radiation surgery using the stereotactic technique was not technically radiosurgery.

In 1948, a patient came to see him with a craniopharyngioma, a pea-sized benign tumour that does not spread and grows incredibly slowly. Because it does not move, it was the perfect test for the polar stereotactic method Mr Leksell used.

However, instead of using narrow beams of radiation, as would be standard with the Gamma Knife, the treatment instead consisted of phosphorus, which punctured the cyst and destroyed it from the inside.

His solution was a diagrammatic coordinate system that consisted of a complex series of concentric circles that compensated for X-ray divergence by calculating the difference between the tube and the developing material.

In a career filled with remarkable innovation and success, this system was one of Lars Leksell’s few failures. First of all, it relied on pneumoencephalography, itself a somewhat archaic imaging method that was not universally used, and the unintuitive coordinates system confused a lot of surgeons, making it difficult to actually apply to neurosurgery.

Regardless, the success of this procedure inspired him to look for an accurate alternative in the field of radiotherapy. It would not take him long to find success.

X-Ray Stereotactic Radiosurgery

With the frame system already a proven success, the next step was to find an alternative treatment system to probes and radioactive injections, both of which required invasive surgery to achieve.

In 1951, Mr Leksell figured out the centre-of-arc radiation principle that proved that multiple small doses of radiation could be focused onto a central point and be highly accurate without damaging healthy tissue surrounding it.

Whilst the principle was effective, exactly which form of radiation could be used at the time was still a point of contention. Gamma rays and ultrasound were considered, but ultimately X-rays were the first radiation outlet to be used.

After some initial experimentation, the first two cases that were successfully treated were both for trigeminal neuralgia, an extremely painful nerve disorder known as the “suicide disease” due to its reputation as being one of the most painful conditions in medicine.

A common treatment for the condition is to intentionally damage the trigeminal nerve that causes the pain, usually undertaken by using a probe or needle to damage the point where the nerve splits into three.

Using the stereotactic frame with a 280-kilovolt X-ray tube, the two people he treated were free of pain for at least two decades, highlighting the potential for the technique, even if an alternative source of radiation was required.

Initially, he tried to use a synchrocyclotron to use proton beams to destroy lesions in the brain, but the system proved to be too complicated and soon abandoned the idea after its introduction in 1958.

By 1960, however, Mr Leksell had found out about cobalt-60, a form of gamma radiation that was more accessible for clinical use and could be integrated into the stereotactic system he already had in place.

This ultimately enabled him to realise his dream of creating a bloodless neurosurgery that could be used as an alternative to conventional neurosurgery in a wide variety of cases in spite of initial scepticism.

Can Personalised Radiotherapy Defeat Bladder Cancer?

Radiotherapy has been in use since around the turn of the 20th century, making it a very well-established area of medicine. Nevertheless, like any other form of medicine, nothing has stood still; as well as establishing more kinds of cancer (and other ailments) that radiotherapy can treat, its use has been refined and new technology developed.

Alongside that has emerged a wealth of research that goes on to this day, highlighting where and when the treatment is most effective, as well as highlighting problems such as temporary and lasting side effects.

What all this has achieved is to enable every radiotherapy centre that exists today to offer better treatment and a wider range of options to patients than was ever the case in the past.

Personalisation Research Shows Promise

Among the areas of research in recent years is the use of more personalised medicine. This approach rejects the assumption that there is a standard one-size-fits-all approach to treatment and operates on the theory that each patient has requirements that are best met by tweaking the treatment according to a specific combination of characteristics.

New research on personalised care has produced some interesting conclusions in the area of muscle-invasive bladder cancer, suggesting this may be a more effective approach to delivering radiotherapy to sufferers.

A study by the Institute of Cancer Research in London, co-funded by bodies in Australia and New Zealand and published in the journal European Urology, has indicated that the use of personalised radiotherapy can be particularly effective for patients with this form of cancer.

A particular difference about this approach is that the amount of radiation delivered to any given part of the body will vary in each session, reducing side effects while in no way diminishing the impact the radiation has on the cancer.

Explaining the significance of this approach, Professor Robert Huddart, one of the leaders of the research, said it “has allowed us to deliver effective treatment safely and allowed us to use a high dose which promises to cure more patients, with relatively few long-term side effects”.

He added that further research would find out more about the effectiveness of this approach in treating cancer in comparison with other methods.

How The Research Was Carried Out

The research split 345 bladder cancer patients into three groups, one of which was treated in a standard way, while the other two received adapted treatment plans, with each patient getting a different treatment each time. One of the latter two groups saw patients receiving higher radiation doses in each session.

Group Leader at the Institute for Cancer Research, London Professor Emma Hall, said: “As medical technologies continue to improve, it means that we can investigate delivering more complicated and personalised forms of radiotherapy to treat certain cancers.”

Such treatments may be of benefit to more than just bladder cancer patients, but help sufferers from many other forms of cancer that are treated with radiotherapy, using modified approaches to suit the circumstances of each patient.

Other Personalisation Research

Indeed, investigating ways to develop the use of personalisation across a range of cancer treatments (not just radiotherapy) using the power of new technologies like artificial intelligence (AI) is central to a new project headed up by the Universita Cattolica in Rome.

Known as the Horizon IHI product, the stated aim is that of developing “Thera4Care – Theranostics Ecosystem for Personalised Care,” (theranostics being the name given to the deployment of next-generation personalised therapies).

With funding of €28 million and 29 partners in industry and academia, this may go a long way towards further advancing the personalisation of radiotherapy for cancer treatments.

This does not necessarily mean that if you come to our radiotherapy centre you will be receiving a personalised treatment. Part of the reason for that is that you may have a cancer where there is already a clear treatment path to take that would not be enhanced by attempting to personalise it.

Alternatively, it may be your condition is in an area where there is insufficient research to date to indicate clearly what benefits (if any) would be gained by taking a novel, non-standard approach to treatment. It is by no means certain at this time that all cancer treatment will be personalised in the future, even after much research has been done.

What you can be assured of is that the radiotherapy treatment you will receive will be the best available, based on the latest research and knowledge, in order to obtain the most optimal outcome for somebody in your condition, whether that includes an element of personalisation or not.

Radiotherapy, like other cancer treatments, will continue to change and advance, but we can provide you with the best treatment there is today.

Who Accidentally Discovered Radiotherapy’s Therapeutic Use?

For over a century, people have gone to radiotherapy centres with the knowledge that they can receive some of the best treatment possible to help remove growths and lesions, treat nerve conditions with the accuracy of a scalpel and provide intensive, effective treatment to battle cancer.

Long before this, radiation has been used to help treat various conditions with varying degrees of success, but one of the biggest breakthroughs and explorations of the effects of radiation on the body that has made over a decade of treatments possible might have come as the result of an accident.

Whilst serendipity is a typical part of scientific discovery, it does not often come from forgetfulness, particularly regarding a material that needs to be handled with utmost care.

A Pocket Full Of Radium

In 1895, Wilhelm Roentgen discovered the X-ray, and within a year several doctors were using it to try and treat cancer without really knowing how it worked.

The same year that Emil Grubbe was trying to treat breast cancer patients with X-rays, Henri Becquerel was studying the nature of radioactivity and where X-rays actually came from.

His work on Uranium would ultimately inspire significant research into radioactivity and radiation, including by Mr Becquerel’s later research partners Marie and Pierre Curie.

Their discoveries would ultimately win the trio a Nobel Prize for Physics in 1903, but two years before this, Henri Becquerel would make his biggest contribution to the medical world, and it was the result of a typical bout of forgetfulness.

Whilst X-rays had been used successfully to treat skin cancers and bouts of lupus, there was no consensus as to why they were effective. Nikola Tesla believed it was a result of ozone, something thoroughly debunked within a year, as was a competing theory that suggested it was electrical discharge.

Radiation sensation

The first attempted cancer treatment using radiation by Victor Despeignes was largely based on an educated guess that turned out to be wrong.

Radiation has a bactericidal effect, and Mr Despeignes believed, wrongly, that cancer was a parasitic growth. However, whilst his conclusion was wrong, his choice of treatment was the right one, even if it ultimately came too late to save his patient.

In 1900, Robert Kienbock determined that the X-rays themselves were the cause of the therapeutic effect, and Otto Walkhoff noticed a very similar effect with radium.

However, Henri Becquerel ultimately became the one to prove this through the absent-minded storage of a sample of radium salts.

He slotted it in a chest pocket on his waistcoat for several hours whilst he worked, thinking nothing of it at the time. However, within a couple of weeks, the skin had developed a particularly severe case of burning and inflammation.

This led him to visit Ernest Besnier of the St Louis Hospital in Paris in 1901. He took a lot at the burn and concluded that he believed it was caused by the radium itself.

The Becquerel burn

The “Becquerel burn”, as it became known, led to another wave of developments in radiation therapy once Marie Curie confirmed the physiological effects on radium.

Once that was confirmed, it started to be used in the same way as X-rays but could be far more versatile in an era before radiation beams, as it could be applied in a range of different ways compared to X-rays.

Radium was not used very often because it was somewhat difficult to acquire until pitchblende extraction techniques were refined, allowing it to be used far more widely, and for decades become one of the most important front-line treatments for cancer.

Unfortunately, whilst he received multiple accolades and looked to have an exceptionally lengthy scientific career ahead of him as the chairman of the Academy of Sciences, his career was tragically cut short as just months after his appointment on 25th August 1908, he died of a cardiac arrest.

It was reported that he also had serious skin burns, which were the results of not carefully handling radioactive materials and wearing protective equipment, providing not only scientific advancement but also an illustration of why they are handled with so much care.

At the age of just 55, he would be the second of the Nobel Prize-winning trio to die after Pierre Curie was tragically killed by a heavy horse cart and unfortunately did not get to see the lasting legacy of his discoveries in the field of medicine.

Much like the Curies, he is immortalised as one of the standard units for radioactivity is named the becquerel, but one of his most pivotal acts was to forget to put radium away properly.
