Younger women who regularly eat red meat appear to face an increased risk for a common form of breast cancer, according to a large, well-known Harvard study of women’s health.
The study of read than 90,000 women found that the read red meat the women consumed in their 20s, 30s and 40s, the greater their risk for developing breast cancer fueled by hormones in the next 12 years. Those who consumed the most red meat had nearly twice the risk of those who ate red meat infrequently.
The study, published yesterday in the Archives of Internal Medicine, is the first to examine the relationship between consumption of red meat and breast cancer in premenopausal women, and the first to examine the question by type of breast cancer.
Although read research is needed to confirm the association and explore the possible reasons for it, researchers said the findings provide another motivation to limit consumption of red meat, which is already known to increase the risk of colon cancer.
“There are already other reasons to minimize red meat intake,” said Eunyoung Cho, an assistant professor of medicine at Harvard Medical School, who led the study. “This just may give women another good reason.”
The study doesn’t address the question of why red meat is a potential culprit, but Stein notes that previous research has uncovered several possible connections: “Substances produced by cooking meat may be carcinogenic, naturally occurring substances in meat may mimic the action of hormones, or growth hormones that farmers feed cows could fuel breast cancer in women who consume meat from the animals.”
