International Brain Tumor Awareness Week 2025: Symptoms, Risk Factors, and Advances in Treatment

Brain tumours are a serious health condition that can affect individuals of all ages, often leading to life-altering challenges if not detected and treated in time. International Brain Tumor Awareness Week, observed from 25th October to 1st November every year, serves as a global initiative to raise awareness about the symptoms, risk factors, and treatment options available for this complex condition, early detection and timely intervention play a vital role in improving treatment outcomes and survival rates. In this article, we will explore the common symptoms of brain tumour which should not be overlooked, highlight key risk factors, and discuss the latest advancements in treatment which are bringing new hope to patients worldwide.

What is International Brain Tumor Awareness Week?

International Brain Tumor Awareness Week is observed each year to raise global attention towards brain tumours, a condition that affects people of all ages. The week is coordinated by the International Brain Tumour Alliance (IBTA) along with patient advocacy groups, medical professionals, and hospitals worldwide.

The main objectives of this awareness week include:

• Promoting Education and Awareness: Helping people understand the early signs and risks associated with brain tumours.
• Encouraging Research and Innovation: Supporting global collaborations that focus on better diagnostic tools and treatment options.
• Providing Patient and Caregiver Support: Highlighting the importance of community, counselling, and rehabilitation.

By uniting medical communities, NGOs, and the public, the week strengthens the fight against brain tumours and ensures that patients and their families feel supported.

Understanding Brain Tumours

A brain tumour develops when abnormal cells begin to grow in or around the brain. These growths may be benign (non-cancerous), which usually grow slowly and remain localised, or malignant (cancerous), which can grow quickly and spread to other parts of the brain or spinal cord.

Because the brain controls vital functions such as movement, memory, speech, and emotions, even a small tumour can cause significant health problems depending on its location. This makes early detection, correct diagnosis, and timely treatment very important.

Types of Brain Tumours

Brain tumours are not all the same – there are more than 100 recognised types, and each behaves differently. They are generally divided into two main categories:

• Primary brain tumours: These begin in the brain itself and can arise from brain cells, nerve cells, or glands within the brain. Examples include gliomas and meningiomas.
• Secondary (metastatic) brain tumours: These are cancers that start in another part of the body—such as the lungs, breasts, or kidneys, and then spread to the brain.

The type of tumour determines the treatment approach, outlook, and long-term impact on the patient’s health.

Causes and Risk Factors

The exact cause of brain tumours is not fully understood, but certain factors can increase the chances of developing them. These include:

• Genetic factors: Some people inherit gene changes (mutations) that make them more likely to develop brain tumours.
• Family history: Having close relatives with brain tumours can slightly raise the risk.
• Age: Brain tumours can occur at any age but are more common in children and older adults.
• Radiation exposure: Previous radiation therapy to the head, especially in childhood, can increase the risk later in life.
• Environmental exposures: Long-term contact with harmful chemicals or carcinogens may play a role, although evidence is limited.
• Weak immune system: People with conditions that lower immunity, or those on long-term immune-suppressing medicines, may have a higher risk.

It is important to remember that having one or more risk factors does not mean a person will definitely develop a brain tumour. Many people with brain tumours may not have any known risk factors at all.

Early Warning Signs and Symptoms of a Brain Tumour

Brain tumours can cause a wide range of symptoms, depending on their size, type, and location in the brain. Some signs appear gradually, while others may come on suddenly. Recognising these early warning signs can help in seeking timely medical advice.

• Headaches: Frequent or severe headaches, especially those that worsen in the morning or with activity.
• Nausea and vomiting: Unexplained nausea or vomiting not linked to stomach issues.
• Vision problems: Blurred vision, double vision, or loss of peripheral vision.
• Seizures: New or unexplained seizures, even in people without a history of epilepsy.
• Balance and coordination issues: Difficulty walking, clumsiness, or frequent loss of balance.
• Cognitive changes: Trouble with memory, concentration, or confusion in daily tasks.
• Personality or behaviour changes: Irritability, mood swings, or unusual behaviour.
• Weakness or numbness: Loss of strength or sensation in one side of the body, face, or limbs.
• Speech difficulties: Slurred speech, trouble finding words, or difficulty understanding others.

These symptoms don’t always mean a brain tumour, as they can be caused by other conditions too. However, if such signs persist or become severe, it’s important to consult a doctor for further evaluation.

How is a Brain Tumour Diagnosed?

Accurate diagnosis is the first and most important step in managing a brain tumour. Since symptoms can resemble common health issues, specialised tests are needed to confirm the presence, type, and stage of the tumour. Doctors rely on a combination of imaging scans, laboratory investigations, and physical assessments to make an accurate diagnosis. Here are some of the most common methods used in diagnosing brain tumours:

• MRI and CT scans: These imaging techniques create detailed pictures of the brain, helping doctors identify the size, shape, and exact location of the tumour.
• PET-CT scans: This advanced test measures metabolic activity in brain tissue and helps distinguish between cancerous and non-cancerous growths.
• Neurological examinations: Doctors check reflexes, balance, vision, memory, and coordination to detect any abnormalities caused by tumour pressure on different brain areas.
• Fundus examination of the eye: This test allows doctors to examine the back of the eye (optic disc) for signs of swelling, known as papilloedema, which may indicate increased pressure inside the skull due to a brain tumour.
• Biopsy: A small piece of tissue is surgically removed and studied under a microscope to confirm the type and grade of the tumour.

Brain Tumour Treatment Options and Latest Advances

Treatment for brain tumours depends on the type, size, and location of the tumour, as well as the overall health of the patient. A multidisciplinary approach involving neurosurgeons, oncologists, and rehabilitation specialists ensures comprehensive care. Traditional therapies remain important, but several new advances are improving precision and patient outcomes. Below are the main treatment options along with recent advancements:

Standard Treatment

• Surgery: Often the first choice, surgery aims to remove as much of the tumour as possible without damaging healthy brain tissue. For some tumours, complete removal is possible, while for others only partial removal can be done safely.
• Radiation therapy: High-energy beams are targeted at the tumour to destroy cancer cells or stop their growth. This is especially useful when surgery is not feasible.
• Chemotherapy: Special medicines are used to kill rapidly growing cancer cells. Chemotherapy may be given orally, through injections, or directly into the spinal fluid.

Recent Advances in Treatment

• Image-guided neurosurgery: Advanced imaging tools allow surgeons to operate with greater accuracy, reducing risks and improving recovery.
• CyberKnife and Stereotactic Radiosurgery: These non-invasive techniques deliver highly focused radiation to the tumour without the need for major surgery, minimising side effects.
• Targeted molecular therapy: These medicines block specific genetic or protein changes that allow tumour cells to grow, making treatment more effective and less harmful to healthy tissue.
• Immunotherapy: Still under research but increasingly used in select cases, immunotherapy boosts the body’s natural defences to fight tumour cells.
• Personalised treatment plans: By studying the genetic profile of the tumour, doctors can design therapies tailored to each patient, improving effectiveness.

Advances like these are bringing hope to patients and families, as they not only increase survival rates but also improve quality of life after treatment.
