Colonoscopies are crucial in the early detection of colorectal cancer, the second leading cause of cancer deaths in the United States. Mercy specialists are experts at this very effective form of detection and treatment, and they want you to be comfortable and informed throughout the entire process, especially in explaining your results. With colonoscopy, abnormal growths can be found and, in most cases, treated at the same time. It’s a way to protect you from colorectal cancer, and early detection is so important.
