Cancer that forms in tissues of the
bladder (the
organ that stores urine). Most bladder cancers are transitional
cell carcinomas (cancer that begins in cells that normally make up the inner lining of the bladder). Other types include
squamous cell carcinoma (cancer that begins in thin, flat cells) and
adenocarcinoma (cancer that begins in cells that make and release
mucus and other fluids). The cells that form
squamous cell carcinoma and adenocarcinoma develop in the inner lining of the bladder as a result of
chronic irritation and
inflammation.
adenocarcinoma (A-deh-noh-KAR-sih-NOH-muh)
Cancer that begins in cells that line certain internal organs and that have gland-like (secretory) properties.

cancer (KAN-ser)
A term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy.

squamous cell (SKWAY-mus sel)
Flat cell that looks like a fish scale under a microscope. These cells cover inside and outside surfaces of the body. They are found in the tissues that form the surface of the skin, the lining of the hollow organs of the body (such as the bladder, kidney, and uterus), and the passages of the respiratory and digestive tracts.

squamous cell carcinoma (SKWAY-mus sel KAR-sih-NOH-muh)
Cancer that begins in squamous cells, which are thin, flat cells that look like fish scales. Squamous cells are found in the tissue that forms the surface of the skin, the lining of the hollow organs of the body, and the passages of the respiratory and digestive tracts. Also called epidermoid carcinoma.
