CHICAGO, Nov. 13 (UPI) -- A new U.S. study says premenopausal women who regularly eat red meat raise their chances of getting a common type of breast cancer.
The study, published in the Archives of Internal Medicine, said growth hormones fed to cattle and other animals encourage the development or hormone-related breast cancer.
About 60 percent of breast cancers are fueled by the hormones estrogen and progesterone, U.S. News & World Report says.
Researchers say premenopausal women who eat more than one and a-half servings of red meat each day nearly double their risk of getting a kind of breast cancer that is linked to hormones.
Study author Eunyoung Cho, an epidemiologist with the Brigham and Women's Hospital and Harvard Medical School, said red meat is also tied to colon cancer, and added she saw little downside in choosing fish or chicken or tofu instead.
