What is colorectal cancer?
Colorectal cancer is a type of cancer that develops in the large intestine. A term colon cancer refers to cancer that develops in the colon, the longest part of the large intestine. The term rectal cancer refers to cancer that develops in the rectum, the final straight part of the large intestine that ends in the anus – the opening of the rectum to the exterior. Cancer may also develop in the anus, but anal cancer is a distinct disease and not covered in this guide.
