Doctors can you tell me when should i be tested for colon cancer?

Information: Certainly by age 40 or sooner if there is family history.

50 if no symptoms: The current recommendations are to get a screening colonoscopy at age 50 if no symptoms and no family history. Certainly sooner if you are having GI problems. Also sooner if family history. For example if parent had colon cancer at 50 you should be screened 10 years earlier at 40.
