Colonoscopy image: rectal cancer
This image shows a mass suspicious for cancer that has developed in the rectum, the last part of the large bowel. Growths like this can cause bleeding from the back passage, difficulty in opening the bowels or a blockage of the bowel. The diagnosis is confirmed by examination of a biopsy taken during colonoscopy. Early diagnosis can make treatment more successful.
In the video below you see the tumour mass lying between 10 and 20 cm up the rectum.
