New research
reveals a direct link between alcohol consumption and colorectal cancer
risk.
Consuming an average of 14 or more alcoholic drinks per week increases
the risk of colon cancer by 25% and more than doubles the risk for rectal
cancer, offering a clear target for those looking to curb risk through
moderation.
The Critical
Number: 14 Drinks Per Week
A landmark study
published in the American Cancer Society’s journal Cancer analyzed
data from nearly 90,000 adults over two decades. It found that individuals with
a lifetime average of 14 or more weekly drinks had a 25%
higher risk of colon cancer and a staggering 95% higher risk
of rectal cancer compared to light drinkers (less than one drink per
week).
Moderation Matters,
But Quitting Helps More
The study
defined moderate intake as 7-14 drinks per week, which carried a
lower risk than heavy drinking. Most encouragingly, the data suggest
that former drinkers who quit may see their risk return to
levels similar to those of light drinkers. “We were encouraged to see that their
risk may return to that of the light drinkers,” said co-senior author Erikka
Loftfield of the National Cancer Institute.
Why This Warning is
Urgent: A Shift in Cancer Demographics
This research adds
urgency to new findings that colorectal cancer is now the leading cause
of cancer death for Americans under 50. “This can no
longer be called an old person’s disease,” said ACS’s Dr. Ahmedin
Jemal. The rising rates in younger adults, combined with the proven link to
alcohol, underscore the importance of lifestyle factors in prevention.
Official Guidance:
“Drink Less
Reflecting this
evolving science, the latest U.S. dietary guidelines have shifted from
recommending a specific drink limit to a broader warning: “Consume
less alcohol.” Experts like Christopher Kahler of
Brown University emphasize that “any level of drinking has some risk, and
it increases with more drinking.”
