Sodas, Other Sweet Drinks Tied to Higher Risk for Endometrial Cancer11/22/13
FRIDAY, Nov. 22, 2013 (HealthDay News) -- Older women who drink
lots of soda and other sugary beverages may be at higher risk for
endometrial cancer, a new study suggests.
Endometrial cancer involves tumors in the lining of the uterus,
and typically affects women in their 60s or 70s, according to the
U.S. National Cancer Institute (NCI).
In the new NCI-funded study, researchers looked at data from
more than 23,000 postmenopausal women in Iowa who were followed
from 1986 to 2010.
They found that those who drank the largest amounts of
sugar-sweetened beverages had a 78 percent higher risk for a tumor
known as estrogen-dependent type I endometrial cancer.
The more sugar-sweetened beverages a woman drank, the greater
her risk, according to the study published online Nov. 22 in the
Cancer Epidemiology, Biomarkers & Prevention.
There was no link between endometrial cancers and consumption of
sugar-free soft drinks, sweets/baked goods and starch.
In a journal news release, study author Maki Inoue-Choi said she
wasn't surprised that increased intake of sugary drinks was tied to
this estrogen-linked cancer.
"Other studies have shown increasing consumption of sugar-sweetened beverages has paralleled the increase in obesity," explained Inoue-Choi, who was a research associate at the University of Minnesota School of Public Health when the study was conducted. "Obese women tend to have higher levels of estrogens and insulin than women of normal weight, [and] increased levels of estrogens and insulin are established risk factors for endometrial cancer."
Inoue-Choi is currently a postdoctoral fellow at the NCI and the
U.S. National Institute on Minority Health and Health
A group representing the beverage industry took issue with the
In a statement from the American Beverage Association, Dr.
Richard Adamson, former director of the NCI's Division of Cancer
Etiology and now a consultant to the group, said that, "this study
does not show that sugar-sweetened beverage consumption causes
Adamson said that, "in fact, its findings conflict with the
results of several other published studies that showed no
association between consumption of sugar and risk for endometrial
He also stressed that the study only showed an association
between sweetened beverage intake and endometrial cancer risk, and
it could not show cause-and-effect. And he noted that people in the
upper one-fifth of sweetened beverage intake had levels ranging
from 1.7 to 60.5 servings per week.
That is "the difference between 1 can and more than three
12-packs a week [in 8-ounce servings]," Adamson said. " This is a
very broad range."
For her part, Inoue-Choi said that since these are the first
findings of their kind, they do need to be reproduced in other
But, she added, "research has documented the contribution of
sugar-sweetened beverages to the obesity epidemic. Too much added
sugar can boost a person's overall calorie intake and may increase
the risk of health conditions such as obesity, diabetes, heart
disease and cancer."
