The terms benign and pseudotumor derive from the fact that increased intracranial pressure may be associated with brain tumors. Those patients in whom no tumour was found were therefore diagnosed with pseudotumor cerebri (a disease mimicking a brain tumor).
Brain tumors are abnormal growths of cells in the brain. 1  Although such growths are popularly called brain tumors, not all brain tumors are cancer. 2  Cancer is a term reserved for malignant tumors. 3  Malignant tumors can grow and spread aggressively, overpowering healthy cells by taking their space, blood, and nutrients.etastatic brain tumors are made of cancerous cells from a tumor elsewhere in the body. The cells spread to the brain from another tumor in a process called metastasis. This is the most common type of brain tumor.
