Concerned by data showing that colorectal cancer rates among younger Americans are growing sharply, the ACS is recommending that all adults at average or low risk get screened for the disease at the age of 45, instead of 50, as it previously recommended. Adults in good health at average risk and a life expectancy of more than 10 years should continue screening through the age of 75, the ACS recommends. Those older than 76 should consult their doctor about a screening schedule. Men and women at high risk, such as patients with a family history of colorectal cancer, may require a more aggressive screening program.
Two-thirds of all colorectal cancer cases are diagnosed in adults 55 to 84 years old, according to National Cancer Institute statistics from 2011-15. But a 2017 study published in the Journal of the National Cancer Institute found that colorectal cancer diagnoses have risen sharply in young adults over the last 20 years. In fact, "age-specific colorectal cancer risk has escalated back to the level of those born circa 1890 ... underscoring the need for increased awareness among clinicians and the general public," the study's authors note.
The ACS also is recommending that doctors give patients a wider range of colorectall cancer screening tests to choose from, in hopes that more choices will result in more screenings. "Ascribing to the adage that the best screening test is the one that gets done, and done well, the ACS recommends that patients ... be offered a choice of tests based on availability of highquality options," the organization said in updating its guidelines. "It is our hope that widespread adoption of this guideline will have a major impact on the incidence, suffering, and mortality caused by colorectal cancer." The ACS advises patients to follow up with a colonoscopy if they receive positive results from tests other than a colonoscopy.
RECOMMENDATIONS INCLUDE (Source: American Cancer Society)
- Stool tests
- Fecal immunochemical test every year
- Highsensitivity, guaiacbased fecal occult blood test every year
- Multi-target stool DNA test (Cologuard) every three years
- Endoscopic or imaging examinations
- Colonoscopy every 10 years
- CT colonography every five years
- Flexible sigmoidoscopy every five years
By reducing the recommended age of colorectal screenings and expanding the number of screening options, the ACS hopes to reduce incidence rates and catch the disease early enough to improve outcomes for more patients. "We have known, in recent years, that colorectal cancer rates in people over 50, who have screening available, have decreased significantly, while colon cancer rates in patients under the age of 50 have risen quite significantly," says Jeffrey Weber, MD, Gastroenterologist in our Phoenix hospital. "We have, for a long time, advocated screening for African Americans starting at age 45, because they are at higher risk for the disease, and I feel that starting to screen the rest of the population at 45 will save many lives."
