(also known as colon cancer, rectal cancer, or bowel cancer) is the development of cancer from the colon or rectum (parts of the large intestine).
It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body.
Signs and symptoms may include blood in the stool, a change in bowel movements, weight loss, and feeling tired all the time.
Most colorectal cancers are due to old age and lifestyle factors with only a small number of cases due to underlying genetic disorders.
Some risk factors include diet, obesity, smoking, and lack of physical activity. Dietary factors that increase the risk include red and processed meat as well as alcohol.
Another risk factor is inflammatory bowel disease, which includes Crohn's disease and ulcerative colitis.
Some of the inherited genetic disorders that can cause colorectal cancer include familial adenomatous polyposis and hereditary non-polyposis colon cancer; however, these represent less than 5% of cases.
It typically starts as a benign tumor, often in the form of a polyp, which over time becomes cancerous.
