Bladder Cancer

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.


  • Blood in the urine (slightly rusty to bright red in color)
  • Frequent urination, or feeling the need to urinate without being able to do so
  • Pain during urination
  • Lower back pain


Different treatments are available for patients with bladder cancer, including clinical trials of new treatments for patients with cancer.
