Colorectal cancer, also known as bowel cancer, can affect any part of the large bowel (colon) and rectum.
Most colorectal cancers develop on the inner wall of the colon and rectum and usually start with growths called polyps.
These polyps are benign growths and usually harmless, however they can become cancerous if left undetected.
Colorectal cancer may also be called colon cancer or rectal cancer, depending on where the cancer is located and the area it originates from.
Colorectal cancer is the most common cancer in men and second most common in women in Singapore and is more common in people over the age of 50.
