Colorectal cancer is a form of cancer affecting the colon and rectum, which are components of the digestive system. They might begin either in the colon or rectum and have similar symptoms. However, the treatment for these cancers differs based on their origin. Cancer often creates an aura of fear but with timely treatment, most cases of the disease can be managed.
The colon and rectum together constitute the large intestine. While colon is a muscular tube of about 6 foot, which originates at the end of the small intestine, rectum has a length of about 8 inches and connects the anus with colon. Colon and rectum help in the processing and excretion of waste from our body.
Colorectal cancer is characterised by abnormal cell growth in the form of polyps or tumours. The polyps usually occur in two types, as adenomas or intestinal polyps and hyperplastic polyps. Some of these polyps might be benign.
