Why is a full bladder often required for external beam therapy?
Answer
To move the bladder away from the prostate for more precise targeting
Many treatment centers implement a bladder protocol that requires patients to have a full bladder during their daily external beam radiation sessions. A full bladder is larger than an empty one, which helps to push the bladder wall further away from the prostate gland. By increasing the physical distance between the bladder and the prostate, medical teams can reduce the amount of radiation the bladder receives, allowing for better shielding of healthy tissue while maintaining precise targeting on the tumor.
