Colorectal cancer screenings include sample testing or examinations
There are two main ways to test for colorectal cancer, and they’re done at different frequencies. Examination-based tests like colonoscopies, in which a doctor looks for swelling or polyps (small abnormal growths) in the lining of the colon, are recommended around every 10 years. Sample-based tests, like fecal immunochemical tests (FITs), are another option for colorectal cancer screening. With these tests, you send a stool sample to a lab for analysis. They’re typically done each year. If your FIT test detects signs of colorectal cancer, your doctor will likely follow up with a colonoscopy.
