Women may have a reason to watch how much red meat they eat. A new report shows a high red meat diet may increase a woman's risk for breast cancer.
Researchers followed over 90,000 pre-menopausal women, ages 26 to 46, for more than a decade.
Women, who ate more than one-and-a-half four-ounce servings of red meat a day, doubled their risk of breast cancer.
That is compared to women who limited their red meat intake to three servings or less a week.
Dr. Wendy Chen of the Dana-Farber Cancer Institute stated, “We believe that if red meat does influence breast cancer risk that it may be due to a hormonally based mechanism.”
Those hormones, doctors say, may be associated with hormone-fed cattle in the United States.
Doctors say the report is not definitive, but does give women more information about the possible risks and control over what and how much they may choose to eat.
