A disease of the cells that line the inside of the bladder. Bladder cancer is a rare disease that is most commonly seen in older adults. It is known to cause blood in the urine in up to 90% of patients at diagnosis. Causes of bladder cancer include smoking, exposure to certain chemicals (arylamines), and chronic bladder infections.
Treatment includes surgery (full or partial removal of the bladder), chemotherapy, immunotherapy (giving certain vaccines into the bladder), or thermotherapy (heating the lining of the bladder combined with chemotherapy). The stage of bladder cancer can vary at diagnosis and throughout treatment. Bladder cancer is staged using the Tumor, Node, Metastasis (TNM) system, as well as Stage Grouping 0, I, II, III, or IV. Staging systems describe the extent of cancer throughout the body and help doctors determine which treatments to offer. The effectiveness of the treatment may depend upon the stage at diagnosis.
