FRIDAY, Feb. 3 (HealthDay News) -- People who consume a few
alcoholic drinks a day and have a family history of colorectal
cancer are at increased risk for developing colon cancer, new
For the study, researchers in Boston examined data from more
than 87,000 women in the Nurses' Health Study and 47,000 men in the
Health Professionals Follow-up Study, and found that 1,801 cases of
colon cancer were diagnosed among the participants from 1980
People with a family history of colorectal cancer who drank an
average of 30 or more grams of alcohol per day (about 2.5 typical
drinks in the United States) were at increased risk for colon
cancer, according to lead author Eunyoung Cho, of the Channing
Laboratory, department of medicine at Brigham and Women's Hospital
and Harvard Medical School, and colleagues.
Those at greatest risk also ate the most red meat, smoked more
and consumed the least folate, which suggests they ate fewer green
vegetables and cereal. The findings indicate that other lifestyle
factors, such as diet, play an important role in colon cancer risk,
the researchers said.
Although the study uncovered an association between these
factors and colon cancer risk, it did not prove a cause-and-effect
Among people who did not have a family history of colorectal
cancer, no significant association was found between alcohol
consumption and colon cancer. Greater alcohol intake was not
associated with a consistent increase in cancer risk, the authors
noted in a news release from Boston University Medical Center.
The study was published in the February issue of the
American Journal of Clinical Nutrition.
