45 is the New 50 for Colon Cancer Screenings

In 2021, the U.S. Preventive Services Task Force brought the recommended age for colon cancer screenings down from age 50 to 45, based on new data.

“Over the last 20 years, new cases of colon cancer and the number of deaths have increased among those under 50 – especially in the 45-50 age group,” says hematologist oncologist Maged Khalil, MD, with LVH Hematology Oncology–1240 Cedar Crest, part of Jefferson Health.

“We think the increase is associated with eating processed food, refined sugars, processed or red meat, not enough fiber, heavy alcohol consumption and long-term smoking as well as higher bodyweight,” says Dr. Khalil. “There are also theories about improper use of antibiotics, which alters gut bacteria.”

Colon cancer is most treatable when found early and colonoscopies are key to those findings. This is a visual test where a clinician looks inside your colon. The screenings can detect the disease and prevent cancer because clinicians can remove precancerous polyps during the procedure.

Other tests involve taking a stool sample at home and mailing it to a lab for testing. There is also a blood test, newly approved by the FDA. Clinicians recommend a colonoscopy when any of the stool or blood tests are positive. Screening starts earlier than age 45 for people with a family history of colon cancer and may be done more frequently.
