Bladder cancer is staged classified by the extent of spread of the cancer and graded how abnormal and aggressive the cells appear under the microscope to determine treatments and estimate outcomes.

Smokers with less functional polymorphisms of N-acetyltransferase-2 known as slow acetylators have a higher risk of bladder cancer than other smokers, presumably because of their reduced ability to detoxify carcinogens. Patients at high risk of progression, typically those with recurrent high-grade tumors with carcinoma in situ after intravesical therapy with BCG, should be considered for radical cystectomy.
