What is a Brain Tumor?
A brain tumor is an abnormal growth of cells within the brain or surrounding structures. Tumors can be benign (non-cancerous) or malignant (cancerous) and may arise from brain tissue (primary tumors) or spread from other parts of the body (metastatic tumors). Depending on its location, size, and type, a brain tumor can interfere with critical brain functions such as movement, speech, memory, and coordination.
