Surgery
Polypectomy
A polypectomy removes polyps — small growths — usually from the bowel during a colonoscopy, to prevent them turning into cancer.
Quick answer
Polypectomy: what it is, why it's done and what happens
A polypectomy removes polyps, which are small growths on the lining of an organ such as the bowel. In the bowel it is usually done during a colonoscopy using a wire snare or other instrument passed through the scope.
- Why it is done: It is used to remove bowel polyps found during colonoscopy or screening, because some polyps can slowly develop into cancer over years.
- What happens: During a colonoscopy, the doctor passes an instrument through the scope to remove the polyp, often using a wire loop with or without electric current.
What it is
A polypectomy removes polyps, which are small growths on the lining of an organ such as the bowel. In the bowel it is usually done during a colonoscopy using a wire snare or other instrument passed through the scope.
Why it is done
It is used to remove bowel polyps found during colonoscopy or screening, because some polyps can slowly develop into cancer over years. It also allows the polyp to be examined in the laboratory.
What happens
During a colonoscopy, the doctor passes an instrument through the scope to remove the polyp, often using a wire loop with or without electric current. No external cuts are needed, and it adds only minutes to the test.
Recovery
Most people go home the same day and return to normal quickly. There may be minor bloating or a small amount of blood in the stool. Larger polyp removals may need more care and follow-up.
Good to know
Risks and things to consider
Risks are small but include bleeding and, rarely, a small hole in the bowel wall, which is more likely with larger polyps. Follow-up colonoscopy timing depends on the number and type of polyps found.

Answers
Polypectomy: frequently asked questions
Does removing a polyp mean I had cancer?
No. Most polyps are not cancerous, but some can slowly become cancerous over years, so removing them is a preventive step. The polyp is examined to check its type.
Will I need another colonoscopy?
Often yes. The timing of follow-up depends on the number, size and type of polyps found, as this affects your future risk. Your team will recommend when to be checked again.
