Urologic cancers include cancers of the bladder, kidney, prostate and testicles, all relatively common. Prostate cancer.

CAUSES
Cancer can grow in the urine collection system, but it is uncommon. Renal pelvis and ureter cancers affect men more often than women and are more common in people older than 65. The causes of this cancer are not completely known. Long-term (chronic) irritation of the kidney from harmful substances removed in the urine may be a factor.
This irritation may be caused by:
Kidney damage due to overexposure to medicines, especially ones for pain (analgesic nephropathy).
Exposure to certain dyes and chemicals used to manufacture leather goods, textiles, plastics, and rubber.
