A sessile serrated lesion (SSL) is a flat or slightly raised bump in the lining of your colon. These lesions are often found during routine colonoscopies. While they may appear benign at first, if left in place they can slowly progress toward colon cancer-even in the absence of dysplasia (early cell changes).
Most people with SSLs don't notice any symptoms, which is why regular screening is so important. When symptoms do occur, they may include:
While the exact causes of sessile serrated lesions are still under study, known risk factors include:

SSLs account for 20-30% of serrated polyps detected during colonoscopies.
No. SSLs must be removed to eliminate the risk of progression to cancer.
SSLs without dysplasia have a lower risk of malignancy, while those with dysplasia show abnormal cell changes and can progress faster to cancer.
Removal typically takes 10-20 minutes, plus additional time for recovery from sedation.
No. You'll be under sedation during the procedure. Some patients experience mild cramping afterward.
Most patients return every 3-5 years, depending on the size, number, and pathology of the removed lesions.
Yes. SSLs are removed endoscopically during a colonoscopy, so no major surgery or hospital stay is required.
Increase your dietary fiber, reduce red meat intake, quit smoking, and limit alcohol consumption to help lower your risk.
Yes. A trained gastroenterologist ensures safe, complete removal and accurate evaluation of the lesion.
SSLs are extremely rare in children. Screening typically begins at age 45 unless there's a strong family history of colon polyps.
