The way pelvic radiotherapy affects people depends the type of cancer, the dose of radiotherapy given, and whether it is external beam or internal radiotherapy. Some possible side effects are:

• Tiredness
• effects on the skin
• changes to the bladder
• intestinal changes
• urinary problems in men
• effects in women, such as premature menopause

Many of these side effects can be managed successfully and will begin to improve a few weeks after the treatment is done. Your cancer doctor, specialist nurse, or radiographer will explain the most probable side effects for people in your situation.
