Are colorectal screening tests done by general practitioner or should they be done by gastroenterologists or other experts?

Different Types: The most basic screening test for colorectal cancer is a digital rectal exam with stool for occult blood testing. This can be done by your primary care physician. More advanced screening such as colonoscopies should be done by experienced gastroenterologists, general surgeons, or colorectal surgeons.

Experts: Colonoscopy is performed both by colon and rectal surgeons and gastroenterologists who are both experts in the field. If cancer is found, surgery is performed by the colon and rectal surgeon.
