One of the most effective steps you can take in preventing cancer is knowing
what tests are available and when you should start making them a regular
part of your medical routine. Colorectal cancer is one of the leading

history of colorectal cancer, you may be a candidate for a screening colonoscopy.
A referral from your doctor is not needed for patients age 45 or older
to schedule a screening colonoscopy.

or bleeding. The colonoscopy uses a small tube-shaped camera that enters
the colon and lets the doctor view the inside. When they find precancerous
growths or structural damage, they can treat the problem before it has
a chance to develop into a serious medical issue.
