Brain tumours can be difficult to diagnose in their early stages because the signs often mimic more common conditions like migraines, anxiety, or fatigue. However, recognising the early symptoms of a brain tumour could lead to faster diagnosis, better treatment options, and improved outcomes.
In this guide, we’ll outline 10 common warning signs to be aware of, and why it’s important to trust your instincts when something feels off.
If you’re experiencing frequent or worsening headaches, especially in the morning or when lying down, it may be a sign of increased pressure in the brain. Not all headaches are serious, but sudden or new patterns of pain should be discussed with your GP.
Seizures are a common symptom of brain tumours, even in people with no history of epilepsy. If you or someone you know experiences a seizure, it’s essential to seek urgent medical attention.
Blurred or double vision, loss of peripheral vision, or unexpected vision issues can occur depending on where the tumour is located in the brain.
Short-term memory issues, forgetfulness, or trouble concentrating can be signs of neurological disruption. These are often dismissed as stress-related, but persistent changes should be assessed.
Gradual or sudden hearing loss in one ear, or persistent ringing (tinnitus), may be associated with tumours affecting the auditory nerves.
Struggling to speak clearly, slurring words, or having trouble naming everyday objects may point to a tumour in the areas responsible for language.
Tumours can affect how the brain controls movement. Sudden weakness, tingling, or numbness in the arms or legs, especially on one side, should never be ignored.
Nausea not related to food poisoning or illness, particularly when combined with other neurological symptoms, can be an early red flag.
Unexplained clumsiness, difficulty walking, or frequent stumbling can indicate a problem in the cerebellum, the brain area that controls balance.
Subtle or sudden changes in mood, motivation, or personality can occur when tumours impact certain areas of the brain. If loved ones notice unusual changes, take it seriously.
Because brain tumours are rare, these signs are often misattributed to less serious conditions. But spotting the early symptoms of a brain tumour and seeking help can make all the difference. Your GP may recommend further investigations like an MRI or refer you to a neurologist if they suspect anything abnormal.
If you experience one or more of these symptoms regularly or notice them worsening, book an appointment with your doctor.
