Bowel cancer, also known as colorectal cancer, can affect any part of the colon or rectum; it may also be referred to as colon cancer or rectal cancer, depending on where the cancer is located.
The colon and rectum are parts of the large intestine.
The colon is the longest part of the large intestine (the first 1.8 metres). It receives almost completely digested food from the ceacum (a pouch within the abdominal cavity that is considered to be the beginning of the large intestine), absorbs water and nutrients, and passes waste (stool/faeces/poo) to the rectum.
