If you have reached your 50th birthday, it’s time to talk with your physician about a colonoscopy. A colonoscopy is a procedure performed for a variety of reasons, but most often to screen for colon cancer. In Delaware, colon cancer is the third leading cause of cancer-related deaths. The good news is, if colon cancer is found early, it is often curable – and that’s why having a colonoscopy is so important. If you don’t have insurance or have a financial need, the Screening for Life program may be able to help.


Learn more about colonoscopies from Dr. Ziyad Wadi from Nanticoke Physician Network Gastroenterology in Seaford.
