Bowel cancer is a type of cancer that originates in the inner lining of the large bowel. The bowel is divided into the small bowel and the large bowel. The large bowel consists of the colon, rectum and anus. Abnormal growth of cells in the inner lining of the bowel can form cluster of cells called polyps, which can either be benign (noncancerous) or malignant (cancerous). Bowel cancer is also known as Colorectal cancer as it can either originate from the large bowel (colon) or the rectum.
The treatment will also depend on the origin of the cancer. Lifestyle-related factors, such as diet, weight and exercise, are associated to bowel cancer risks. Bowel cancer is more common in older people, people with family history or inherited genetic syndrome (i.e. Familial Adenomatous Polyposis (FAP) or Lynch syndrome), and people with medical conditions such as inflammatory bowel disease (i.e. Crohn’s disease or ulcerative colitis).
