Cancer Definition

Cancer: Cancer is an uncontrolled growth of cells in the body. Cancer can form tumors, invade surrounding healthy tissues (called local invasion), and slip into the circulation to start new growths in distant sites (metastasis). Cancers are usually named for the body part or type of cell in which they arise. Cancer that has spread is sometimes called systemic cancer.
