The early diagnosis and localization of colorectal cancer is possible with the tools already available: digital rectal examination, proctosigmoidoscopy and/or colonoscopy, barium enema with air contrast and guaiac testing for occult blood. These modalities of treatment combined with a high index of suspicion can detect colorectal cancer at an early stage and achieve cure rates of up to 75-80 percent.
