What should I know about screenings?
Colon cancer often begins as a growth called a polyp inside the colon or rectum. Screenings can find abnormalities early and even prevent cancer.
There are two ways to screen for colon cancer.
Stool-Based Tests
These tests check for cancer in the stool (feces) and can be done at home with a special kit prescribed by your doctor.
Colonoscopies
Your doctor will look at the inside of your colon with a scope that contains a light and tiny camera. They can then remove any abnormalities that are seen and check for cancer.
Do I need to be tested?
Yes if:
- You are a man or woman who is 45 or older.
Maybe if:
- You or a close relative has had colorectal polyps or colon cancer.
- You have an inflammatory bowel disease, such as Crohn’s or ulcerativecolitis.
- You have certain genetic syndromes.
How often should I be tested?
Stool-based tests should be performed every year, and colonoscopies every 10 years.
What happens if you find something?
If your test results don’t come back as normal, your doctor will let you know if you need treatment.
What will happen during the screening?
Preparing for Your Colonoscopy
Your doctor will provide you with specific instructions, which will probably include drinking a special liquid the night before your test to empty your colon and rectum.
Before Your Colonoscopy
You’ll be given a sedative to make you feel relaxed and sleepy.
During Your Colonoscopy
You’ll be asked to lie on your side with your knees pulled up. The doctor will insert a colonoscope into your rectum to view the inside. You will be sedated for this procedure.
Duration
The test usually takes about 30 minutes.
