What is radiation proctitis?

Radiation proctitis refers to rectal complications caused by pelvic malignant tumor patients receiving radiation therapy or after radiation therapy. Erosion, ulcer or bleeding of rectal mucosa occurs, often manifested as abdominal pain, diarrhea, bloody stool, or purulent bloody stool, etc. Acute radiation proctitis usually occurs 1 to 2 weeks after radiation therapy, while chronic radiation proctitis usually occurs months or years after radiation therapy, often with rectal stricture and defecation difficulties. There is no specific drug or treatment for radiation proctitis, but prevention is the key.
