Colorectal cancer is generally identified and diagnosed during the process of colon cancer screening. A colonoscopy procedure is the most common, accurate, and comprehensive testing option for finding colon and rectal cancer. Further exams (like virtual colonoscopy, flexible sigmoidoscopy, double-contrast barium enema, and fecal tests) may also be conducted when screening for colorectal cancer. Your Adult Gastroenterology Associates GI specialist can recommend the best method of screening and diagnosis for your personalized needs.
