The human body is composed of trillions of cells. Each cell’s lifespan differs based on their location in the body. Normally cells grow and divide as the body needs them. Old or damaged cells die and new cells take their place. Cancer is a broad word related to many different diseases. In all types of cancer the body’s cells begin to divide without stopping and spread into surrounding tissues. The cells that are old and damaged do not die, and new cells form when they are not needed. This cell division which becomes out of control can grow into a separate mass (a tumor). Cancers of the blood do not typically form tumors. Cancer becomes very severe when it spreads from where it originated to another part of the body. At this point, the cancer is called metastatic.
