TYPES OF CANCER

• Carcinoid tumors are a type of neuroendocrine tumor that is slow growing and

usually found in the rectum and small intestine.

• Carcinomas are the most common type of cancer that originate in the skin, lungs, breasts, prostate, colon, bladder and other organs and glands. They begin in the lining layer of organs.

• Hematologic (blood) cancers primarily affect blood, bone marrow and lymph

nodes, and may or may not create an actual tumor.

• Leukemia begins in the blood-forming tissue of the bone marrow, blocking the

production of normal white or red blood cells. It does not form solid tumors.

• Lymphoma begins in infection-fighting cells of the immune system, called

lymphocytes, in the lymph nodes and other organs of the body.

• Multiple myeloma begins in plasma cells, a type of immune cell, and builds up

in the bone marrow and forms tumors in bones throughout the body.

• Sarcomas are rare and form in bone and soft tissues, including muscle, fat,

tendons, blood vessels and cartilage.
