There are two types of brain tumors, which are abnormal growths of tissue in the brain. One type is benign and other, malignant. The terms refer to how fast they grow and how much they invade surrounding tissues or move to separate areas of the body.
Benign tumors are slow-growing, are not likely to spread, and can often be treated and/or removed. Though they are termed “benign,” they can still cause severe pain, brain damage and death. They also do occasionally become malignant.
