Hello! Thank you for the query. Such colonoscopy result can indicate inflammatory bowels disease like Ulcerative Colitis. This type of disease are autoimmune. Due to immune system hypersensitivity and activation, intestine cells are attacked by host immune system. This causes chronic inflammation and can lead to intestine narrowing, fistulas, bowels obstruction. This is not a cancer, but it is chronic disease. The final diagnose can be established basing on histopathology result. Hope this will help. Regards.
