Karen Sieve says her family history of colon cancer led her to get her first colonoscopy, despite being active and feeling great. She says her first screening showed two precancerous polyps. She was not scheduled to be seen again for three years. After a just a few months she began feeling tired and short of breath. That's when she went to Siteman. Sieve underwent surgery and her original cancer was completely resected. Sieve participated in a clinical trial and says she was pleased to be able to help others on her journey to being cancer free.
