Hi @suerc, Polyps in the colon are very common and most polyps are not cancerous. 3 years ago I also had a polyp removed and sent to pathology. It turned out to be an adenoma - a PREcancerous polyp. When a precancerous polyp is found, it is likely that more frequent colonoscopies will be recommended. It typically takes years for a precancerous polyp to develop into cancer. So with proper screening, colon cancer can be stopped in its tracks.
