Serrated Polyp

What Serrated Polyps Are

Serrated polyps are abnormal growths that form on the inner lining of the colon or rectum. When viewed under a microscope, they have a saw-tooth or serrated pattern, which gives them their name. There are three main types of serrated polyps: hyperplastic polyps, sessile serrated polyps (also called sessile serrated adenomas), and traditional serrated adenomas. Hyperplastic polyps are usually small and common, and they rarely turn into cancer. Sessile serrated polyps and traditional serrated adenomas tend to be larger and have a higher chance of becoming cancerous if they are not removed.

Why Serrated Polyps Matter in Cancer Care

While many serrated polyps are harmless, having multiple or large serrated polyps can increase the risk of colorectal cancer. This is especially true in a condition called serrated polyposis syndrome (SPS), where numerous serrated polyps develop throughout the colon. SPS itself usually does not cause symptoms, so it can go unnoticed without screening. People with SPS have a higher chance of developing colorectal cancer over their lifetime. Because of this, doctors recommend regular colonoscopies to find and remove these polyps before they can turn into cancer.

What Patients Might See or Hear About Serrated Polyps

If your doctor mentions serrated polyps, it may be after a colonoscopy or biopsy report. You might hear about different types of serrated polyps or about serrated polyposis syndrome if many polyps are found. Sometimes, these polyps are flat and harder to spot during colonoscopy, so careful monitoring is important. You may be told that removing polyps helps lower cancer risk. If you have SPS, your doctor might recommend colonoscopies every one to three years to keep track of new polyps.

How Serrated Polyps Are Diagnosed and Managed

Diagnosis of serrated polyps and SPS is made through colonoscopy, where the doctor looks inside the colon and rectum with a camera. The number, size, and location of serrated polyps are important for diagnosis. For SPS, criteria include having five or more serrated polyps larger than 5 millimeters in the colon (with at least two larger than 10 millimeters) or having more than 20 serrated polyps of any size throughout the colon. Managing serrated polyps usually involves removing them during colonoscopy to reduce cancer risk. If polyps are very large, numerous, or grow quickly, surgery may be needed to remove part or all of the colon.

What Serrated Polyps Do Not Automatically Mean

Finding a serrated polyp does not mean you have cancer or will definitely get cancer. Many serrated polyps, especially small hyperplastic polyps, are harmless. Also, the term serrated polyp alone is not a diagnosis or treatment plan. It is important to understand how this finding fits your personal health situation. Always ask your care team what serrated polyps mean for you specifically.

Questions to Ask Your Care Team

If serrated polyps come up in your care, consider asking: What type of serrated polyp do I have? How many polyps were found, and what sizes? Do I have serrated polyposis syndrome? What does this mean for my cancer risk? How often should I have colonoscopies? What can I do to lower my risk? Should family members be screened? Understanding these details can help you and your caregivers make informed decisions.

Reading Serrated Polyps in Context

Because serrated polyps vary in type and risk, it is important not to focus on the word alone. Instead, look at the full medical report, including the number, size, and type of polyps, and any recommendations from your doctor. This helps avoid unnecessary worry or misunderstanding. Your healthcare team can explain what the findings mean for your health and next steps.

Important Safety Note

This information is educational and does not replace medical advice. It cannot determine what is safe or appropriate for any individual. If you see the term serrated polyp in your medical records or hear it from your doctor, the best step is to ask your care team to explain what it means for your specific situation.

Next Steps for Patients and Caregivers

If serrated polyps are found, follow your doctor’s recommendations for colonoscopy and polyp removal. Keep track of your screening schedule and report any new symptoms. If you have a family history of serrated polyps or colorectal cancer, discuss early screening with your healthcare provider. Staying informed and involved in your care helps reduce cancer risk and supports your health over time.
