Brain tumor

Neoplasm in the brain

A brain tumor (sometimes referred to as brain cancer) occurs when a group of cells within the brain grow out of control, creating a mass. There are two main types of tumors: malignant (cancerous) tumors and benign (non-cancerous) tumors. These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors.
