Screening for colon and rectal cancer
Finding colorectal cancer before it has a chance to develop.
Screening for any cancer means undergoing tests for the disease even if you don’t
have symptoms. And since early detection improves the chances of beating colorectal
cancer, screening is important.
Colon and rectal cancer screening tests can be divided into 2 broad groups:
- Tests that can find both colon and rectal polyps and cancer. These tests look at
the colon’s structure for any abnormal areas. This is done either with a scope inserted
into the rectum or with X-ray imaging tests. Polyps found before they have a chance
to become cancerous can be removed.
- Tests that mainly find cancer. These involve testing the stool (feces) for signs
that cancer may be present. They are less invasive and are easier to have done.
However, they are also less likely to detect polyps.
Who should be screened for colon and rectal cancer?
You should seek your doctor’s advice about how often to undergo a screening test.
However, it is recommended that after reaching the age of 50, both men and women
at average risk for developing colon or rectal cancer should begin regular screening.
African Americans have a higher colon cancer risk and should talk to
their doctor about getting screened starting earlier.
