Is Your Headache a Sign of a Brain Tumour?

We have all likely experienced a headache at some point – some of us may even experience migraines, or tension headaches occasionally. While these episodes can last from hours to days, feel very painful and affect your daily life, they do not usually point toward a severe underlying issue, such as a brain tumour.

Frequently, a headache caused by a brain tumour has different characteristics compared to other types of headaches. And often, patients with brain tumours have more symptoms than just a headache.

What is a brain tumour?

A brain tumour is the abnormal growth of cells in the brain or central nervous system. Brain tumours vary in their nature, ranging from benign (non-cancerous) tumours, which grow slowly and are less likely to recur, to malignant (cancerous) tumours, which can proliferate and invade surrounding tissue.

What are the symptoms of a brain tumour headache?

A headache stemming from a brain tumour can present as a persistent and progressively worsening pain.

Unlike tension headaches that might be triggered by stress, or migraines that might be associated with certain foods or sounds, these headaches do not have the same triggers. They also worsen with activities that increase the pressure inside the head, like bending over, lifting heavy objects, or sudden movements.

Often, a headache brought on by a brain tumour is generally more severe upon waking in the morning and may improve throughout the day. This can be attributed to the body's position during sleep, which can result in increased pressure inside the brain, leading to heightened pain upon awakening.

It is important to note that brain tumour headaches tend to intensify over time. As the tumour grows, more pressure is exerted on the surrounding brain tissues, leading to escalating discomfort.

What is the difference between a brain tumour headache, migraine and tension headache?

There are some distinctions between a headache caused by a brain tumour and those caused by tension headache or a migraine. These differences can be broadly categorised by their origin and nature of pain, their accompanying symptoms, and their triggers and duration. Understanding the distinctions between these types of headaches is important, and can alert you when you might require a doctor to take a closer look. We’ve condensed the most relevant distinctions between the 3 types of headaches in the table below.

Which symptoms should I look out for with a brain tumour?

Brain tumours can cause an array of neurological symptoms that reflect the area of the brain that's affected. These symptoms can vary widely in their nature and severity, but there are several common signs to be aware of. Some of these include:

• Cognitive difficulties. Unexplained difficulties in thinking, concentrating, making decisions, or remembering things can signal a brain tumour. These changes might also involve problems with comprehending written or spoken language, which is a condition known as dysphasia.
• Visual changes. Changes in vision, such as brief episodes of blurred or double vision, or seeing flashing lights, can sometimes be a sign of a brain tumour. Other visual symptoms may include unexplained eye pain or unusual eye movements.
• Difficulty swallowing
• Speech difficulties. Brain tumours can sometimes lead to difficulties with speech. This can manifest as slurred speech, difficulty finding the right words, or problems understanding speech.
• Seizures or convulsions
• Nausea, dizziness or vomiting
• Altered sensation. In addition to facial numbness, changes in sensation could also affect other parts of the body. Patients may experience strange sensations, hypersensitivity or decreased sensitivity to touch, temperature, or pain.
• Mood swings. This can include changes in personality or mental state, and more specific alterations can include rapid mood swings - depression or increased irritability.
• Hormonal changes. If the tumour is affecting the pituitary gland, hormonal imbalances can occur, leading to symptoms like unexplained weight change, fatigue, low libido, menstrual changes in women, or impotence in men.
• Sleep problems. These can include insomnia, oversleeping or disturbances in the sleep-wake cycle.
• Change in sense of smell or taste. Some people may notice a decreased ability to smell or changes in their sense of taste.
• Clumsiness
• Limb weakness in an arm or leg, or weakness or paralysis, especially if it’s on one side of the body

How are brain tumours treated?

Brain tumours are treated through a personalised, patient-centred approach. Treatment plans are carefully developed based on key factors such as the tumour’s type, size, and location, as well as the patient’s age and overall health. The main aim is to effectively control or remove the tumour while preserving surrounding healthy brain tissue.

Surgical intervention is the first line of treatment when the tumour is amenable to safe removal. With the help of advanced approaches such asminimally invasive surgery, real-time imaging and neuro-navigation systems, a precise operation can be performed to remove the tumour fully. For some patients, awake brain surgery with brain mapping can also be beneficial when the tumour is encroaching on healthy brain tissue.

For tumours located in challenging locations or those which cannot be entirely removed surgically, radiotherapy comes into play. Radiotherapy employs high-energy radiation to eliminate tumour cells. Further, chemotherapeutic drugs are often used in combination with surgery and radiotherapy for types of tumours that respond well to such treatments.

Emerging approaches like immunotherapies and precision therapies also form a part of the therapeutic arsenal against brain tumours. Immunotherapies seek to empower the body's immune system to combat cancer cells, whereas precision therapies target the unique biological attributes of the tumour cells.

It should be noted that this isn’t the full spectrum of treatments available for brain tumours, and appropriate treatment options are always best proposed by your doctor.

While the chance your headache is a sign of a brain tumour is slim, if you have persistent or unusual headaches, it’s crucial that you seek professional medical advice from a neurosurgeon, who will be able to diagnose and treat your condition by designing a thorough treatment plan and offering consistent support and aftercare throughout your path to recovery.
