Signs & symptoms : Signs & symptoms drive medical decision making. This means knowledge of natural history of diseases & how disease effects a pt (pathology). If you have signs & symp of colon cancer, then your doctor will investigate that possibility. Just cause you think you have something doesn't mean you have it. Why are you so adamant about colon cancer? Tests for colon cancer are invasive & carry risks.

Too young: Unless you have bad genetic mutation and/or terrible luck, colon cancer is exceeding rare for a 21 year old. Screening colonoscopy has an unacceptable complication vs benefit ratio when performed on an asymptomatic, normal risk young person.
