Both colonoscopy and FOBT are options for CRC screening. For those at an average risk of developing CRC, screening should start at age 50 years. The 2 screening options most often selected are colonoscopy every 10 years and annual FOBT. While FOBT is noninvasive, if a positive result is found, then a colonoscopy is recommended. Over the course of multiple years of screening, false-positive FOBT results leading to colonoscopies may occur often enough that the advantage of using the noninvasive test is lost for some patients.
