Colorectal cancer, otherwise known as bowel cancer, is the third most common cancer. In 40% of cases,
it occurs in the colon, also known as the large intestine, and in 60% of cases in the rectum, located in the latter end of the large intestine. This type of cancer generally affects people over the age of fifty. Disregarding age, the main sources for the emergence of bowel cancer are:
- the presence of a benign colorectal tumor (polyp or adenoma),
- genetic predisposition,
- if you are a carrier of inflammatory bowel disease.
Colorectal cancer develops slowly.
It originates in the emergence of polyps in the lining of the colon. Polyps may be benign, but after a few years they become enlarged and develop into a malignant tumor. This can often result in imperceptible bleeding. When the cancer is at an advanced stage, it may spread to lymph nodes, then the liver, ultimately spreading
throughout the body in the form of metastases.
