Radiation proctitis occurs when radiation therapy used to treat cancers-such as prostate, cervical, or rectal cancer-damages the lining of the rectum. There are two forms: acute proctitis, which starts during or shortly after treatment, and chronic proctitis, which can develop months or even years later. Both types lead to inflammation and soreness of the rectal tissue.
You may experience a range of symptoms, from mild irritation to more serious issues, including:

Radiation proctitis is inflammation and swelling of the rectal lining caused by radiation therapy, commonly used to treat cancers near the rectum.
Acute symptoms often begin during or within six weeks of radiation therapy. Chronic symptoms can appear months to years after treatment.
The ICD-10 code for radiation proctitis is K62.8, which covers other specified diseases of the anus and rectum.
Prevention isn't guaranteed, but modern radiation techniques and careful planning help reduce the risk of rectal damage.
There's no single cure, but a combination of dietary changes, medications, and therapies effectively manages and relieves symptoms.
Schedule an evaluation if you experience rectal pain, bleeding, persistent diarrhea, or any new bowel changes after radiation therapy.
Yes. A low-residue diet with adequate fluids and fiber can soften stools, reduce irritation, and improve overall bowel comfort.
Noninvasive options include anti-inflammatory enemas or suppositories, oral medications like sucralfate, and hyperbaric oxygen therapy.
Many patients experience significant improvement after several hyperbaric oxygen sessions, as the therapy promotes healing of damaged tissues.
If bleeding or symptoms persist despite conservative measures, endoscopic treatments such as argon plasma coagulation may be recommended.
