Renal Pelvis/Ureter Cancer
Cancer of the renal pelvis or ureter is cancer that forms in the kidney’s pelvis or the tube (ureter) that carries urine from the kidney to the bladder.
Cancer can grow in the urine collection system, but it is uncommon. Renal pelvis and ureter cancers affect men more often than women. These cancers are more common in people older than 65.
The exact causes of this cancer are not 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 from medicines, especially ones for pain (analgesic nephropathy)
• Exposure to certain dyes and chemicals used to manufacture leather goods, textiles, plastics, and rubber
People who have had bladder cancer are also at risk.
