What is postoperative radiotherapy for bladder cancer?

Postoperative radiotherapy for bladder cancer refers to the use of radiation therapy after patients have undergone radical surgery for bladder cancer, with the aim of further eliminating any potentially remaining tumor cells. This treatment approach is primarily suitable for patients who cannot tolerate chemotherapy or who refuse to undergo chemotherapy. Radiotherapy methods typically include localized radiation and whole-bladder radiation: localized radiation delivers a high radiation dose specifically to the tumor site, while whole-bladder radiation irradiates the entire bladder. Radiotherapy for bladder cancer offers several benefits and effects, including reduced bladder wall thickness, increased bladder capacity, improved urethral sphincter function, pain relief, and alleviation of symptoms associated with radiation cystitis. However, radiotherapy may also cause certain side effects, such as gastrointestinal effects, and damage to the bladder and urethra. Patients need to undergo treatment under the guidance of professional physicians.
