Prostate cancer has recently surpassed lung cancer to become the most common cancer of American men. The estimated number of new prostate cancer cases in 2005 is expected to be 232,090, up from 198,000 in 2002. Prostate cancer represents 29% of all new cancer diagnoses in men and is comparable to the incidence of breast cancer in women. Prostate cancer continues to disproportionately affect minority men. For patients with early, localized prostate cancer, there are a number of treatment options, including surgical removal of the prostate, radiation therapy (external beam or implantation of radioactive "seeds"), hormonal therapy, cryoablation, or expectant monitoring ("watchful waiting"). Most of these currently available treatments for localized prostate cancer carry the risk of a number of iatrogenic symptoms, including urinary incontinence, ED, and others that vary depending on the treatment received.
