Radiotherapy to the pelvic area of a man

Radiotherapy treats cancer by using high-energy x-rays which destroy cancer cells, while doing as little harm as possible to normal cells. Radiotherapy to the pelvic area may cause long-term changes in the structures and organs in the pelvic area. In a man this includes:

  • the prostate gland
  • the testicles
  • the penis
  • the bladder.
