A brain tumour is an abnormal growth of cells within or around the brain. Brain tumours may be benign (non-cancerous) or malignant (cancerous), and not all brain tumours are cancer. Symptoms depend on the size and location of the tumour and may include persistent headaches, repeated vomiting, seizures, weakness of the arms or legs, changes in vision, difficulty speaking, or changes in memory and behaviour.
While these symptoms do not always indicate a brain tumour, they should never be ignored if they are persistent or worsening. Modern imaging techniques help doctors diagnose brain tumours accurately, and treatment may involve surgery, radiation therapy, chemotherapy, or a combination of these approaches. Early diagnosis provides more treatment options and can significantly improve outcomes and quality of life.
