Colon polyps are small growths that develop on the inner lining of the bowel (colon). They’re quite common—up to 50% of people will have them at some point in their lives.
Most polyps are harmless and don’t cause any symptoms. In fact, they’re often found by chance during routine screening tests or other procedures. However, over time, some polyps can grow larger and may develop into bowel cancer if left untreated.
The good news? Removing polyps (a procedure called polypectomy) can significantly reduce your risk of developing bowel cancer.
Because some polyps can turn into cancer over many years, finding and removing them early is a powerful way to prevent serious disease. That’s why screening and surveillance are so important—even if you feel perfectly well.
If polyps are found during your colonoscopy, your doctor will usually remove them straight away. Once you’ve had polyps, you’re more likely to develop new ones in the future. That’s why your doctor will recommend a surveillance plan—this means having repeat colonoscopies at regular intervals to catch and remove any new polyps early.
The timing of your follow-up will depend on:
The number and size of the polyps
The type of polyps found
Their location
Your personal and family medical history
This tailored approach helps ensure you get the right care at the right time.
If you’ve had polyps, staying on top of your surveillance schedule is one of the best ways to protect your health. Talk to your gastroenterologist if you have questions about your risk or your next colonoscopy.
