Colorectal oncology

Most colorectal cancers are adenocarcinomas. These cancers start in cells that make mucus to lubricate the inside of the colon and rectum. When doctors talk about colorectal cancer, they're almost always talking about this type. Some sub-types of adenocarcinoma, such as signet ring and mucinous, may have a worse prognosis (outlook) than other subtypes of adenocarcinoma. The colon absorbs water and salt from the remaining food matter after it goes through the small intestine (small bowel). For colorectal cancer, this generally includes a surgeon, medical oncologist, radiation oncologist, and a gastroenterologist. A gastroenterologist is a doctor who specializes in the function and disorders of the gastrointestinal tract.
