This cancer forms in tissues of the bladder. 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.
