No. In fact, we see many patients with late onset radiation injury, and just like some complicated diabetic wounds, they are often treated with hyperbaric oxygen therapy. Symptoms of radiation injury usually occur where there is injury to the specific area that was irradiated. For example, abdominal radiation can lead to chronic abdominal pain, pelvic pain, or blood in the urine or stool. Head and neck radiation can often lead to problems healing in the mouth after dental procedures. Sometimes, radiation injury can even lead to non healing wounds on the skin as well. Any unusual symptom that develops months to years after radiation therapy should be investigated for late onset radiation injury.
