Give me a hint. what kind of hassle am i facing if doc suspects colon radiation? what is required to diagnose?

Radiation enteritis: Chronic radiation colitis may cause variety of symptoms such as diarrhea, nausea, weight loss, abdominal pain, intestinal obstruction/perforation etc- depend on the extent of the injury the diagnosis is usually made by suggestive radiologic findings in patients with compatible clinical features who have a history of prior radiation exposure. Colonoscopy is also helpful in making a diagnosis.
