Why do I have to keep my bladder full?

Your radiation treatment is designed to minimize the amount of radiation to the bladder. Your bladder sits on top of the prostate. It is easier to limit radiation exposure when it is filled like a balloon. When it is empty and flat, it will get more radiation than needed and this will increase the risk of long term urinary side effects.

Food and the bladder

Taking good care of your bladder is important at all times, including during radiation treatments. Below is a list of foods that are bladder friendly, and a list of foods that patients should avoid. Consuming the recommended foods will not only help your bladder, but your overall health.

  • avocados, broccoli, cabbage, carrots
  • celery, cucumber, mushrooms, peas

How much exercise do I need?

While food choices are always important, so is the need to exercise. We recommend that patients get at least 150 minutes of moderate intensity or 75 minutes of vigorous intensity aerobic exercise (walking, jogging, cycling, swimming) each week. In addition, two to three resistance exercise (lifting weights) sessions each week involving moderate to vigorous intensity exercises targeting the major muscle groups.
