A brain tumour is an abnormal growth of tissue in the brain or central spine that can interfere with normal brain function. Doctors refer to a tumour based on where the tumour cells originated, and whether they are cancerous (malignant) or not (benign). Severe headaches, seizures, difficulty with balance or coordination, numbness, weakness or tingling, problems with hearing, vision or speech are a few symptoms that need further investigation. #WorldBrainTumourDay
