WHEN TO SCREEN FOR COLON CANCER

Screening begins at 45

The rising rate of colorectal cancer among younger people is one of the reasons the American Cancer Society (ACS) lowered its recommended screening age from 50 to 45.1 Doing so has increased awareness, with the goal of saving more lives. So if you’re already, or about to turn 45, now is the time to start planning your first screening.

With screening, timing is everything 

Colon cancer can take about 10 years to develop.6 By the time symptoms manifest, it may be so advanced that treatment is more difficult, with diminishing chances of survival. Early detection can mean a world of difference when the cancer is still small and has not yet spread. The only way to do this is to get timely and regular screenings.


If you’re 45, take this as a sign to get screened. Share with your family and friends and help spread the word. And if a colonoscopy is overwhelming, especially for first-timers, let them know there are several noninvasive, use-at-home screening options to choose from, such as Cologuard.
