The National Cancer Institute has defined cancer as a group of diseases in which abnormal cells divide without control and are able to invade other tissues. Cancers can be broadly categorized into five groups depending on their origin: carcinoma (skin), sarcoma (bone, cartilage, fact muscle, and blood vessels), leukemia (blood-forming tissue and bone marrow), lymphoma/myeloma (cells of the immune system), and central nervous system (brain and spinal cord).
