Cancer is characterized by proliferation of abnormal cells which multiply out of control, reproducing for no obvious reason. These cancerous cells are not receptive to the normal signal to stop reproducing and this unchecked growth spreads through the body, interfering with the ability of cells, organs, and other structures to perform their normal functions.

There are many forms of cancer that affect the human body. Carcinoma cancers affect the tissue that covers internal organs. Leukemia cancer grows in blood-forming tissue. Sarcoma cancers affect the blood vessels, bone, fat, muscle and other connective tissues. Lymphoma cancer starts in the cells of the immune system and then can spread to other parts of the body.
