Colorectal polyp
Colorectal Polyp
A Colorectal Polyp (pronunciation: /koʊləˈrɛktəl ˈpɒlɪp/) is a small clump of cells that forms on the lining of the colon or rectum. Most colorectal polyps are harmless, but over time, some types can develop into colorectal cancer, which is often fatal when found in its later stages.
Etymology
The term "colorectal" is derived from "colon" and "rectal", the two areas of the body in which these polyps are found. "Polyp" comes from the Greek word "polypus", meaning "many footed", due to the polyp's resemblance to a small, footed creature.
Types of Colorectal Polyps
There are two main types of colorectal polyps: adenomatous and hyperplastic. Adenomatous polyps (adenomas) are the type that can change into cancer, while hyperplastic polyps are more common and are typically not pre-cancerous.
Symptoms
Most colorectal polyps do not cause symptoms. When they do, they may cause rectal bleeding, changes in stool color or consistency, changes in bowel habits, abdominal pain, and anemia due to blood loss.
Diagnosis
Colorectal polyps are often found during regular screening tests for colorectal cancer, such as colonoscopy or sigmoidoscopy. If a polyp is found during one of these tests, it may be removed and sent to a lab to check for cancer cells.
Treatment
Treatment for colorectal polyps usually involves their removal during a colonoscopy or sigmoidoscopy. If a polyp cannot be removed during these procedures, surgery may be required.
Prevention
Prevention strategies for colorectal polyps include regular screening, maintaining a healthy diet, regular exercise, and avoiding tobacco and excessive alcohol.
