A colonoscopy is a vital screening tool that helps detect and prevent colorectal cancer. At Spectra Health, we emphasize the importance of this procedure in identifying and removing precancerous polyps before they turn into cancer. What Makes Colonoscopies So Important? 1. Detects and removes polyps before they become cancerous. 2. Helps diagnose conditions like inflammatory bowel disease (IBD) and chronic digestive problems. 3. Recommended for individuals over 45 or those with a family history of colorectal cancer.
