Bowel cancer, also known as colorectal cancer, is the second biggest cause of cancer death in Australia.
It can occur in any part of the colon or rectum, either growing from the inner lining of the bowel or from small growths on the bowel wall called adenomas or polyps.
Undetected, bowel cancer can spread into the wall of the bowel, the lymph nodes (glands) and then to other organs.
If you are 50 or over, you are at higher risk. But if detected early, 90% of bowel cancers are cured.
