New Study Links Cow's Milk To Increased Breast Cancer Risk

by | February 28, 2020

A new study has illustrated that consumption of cow’s milk can put a person at a greater risk of breast cancer.

The study — Dairy, soy, and risk of breast cancer: Those confounded milks — took place at Loma Linda University in California, and has been published in the International Journal of Epidemiology.

“Strong Evidence”

Researchers discovered that “even relatively moderate amounts of dairy milk consumption can increase women’s risk of breast cancer – up to 80 percent depending on the amount consumed.”

A summary paper of the research explained there is “fairly strong evidence that either dairy milk or some other factor closely related to drinking dairy milk is a cause of breast cancer in women.”

The paper goes on to suggest that the US dietary guidelines of drinking three cups of cow’s milk a day should be viewed with “caution.”

Cow’s Milk & Breast Cancer

Nearly 53,000 women took part in the research over eight years, and were all cancer-free at the beginning of the study. At the end of the eight years, 1,057 of the women had breast cancer.

All of the study participants were required to complete food questionnaires, as well as give information about family history of cancer, medication use, alcohol consumption, and physical activity levels.

Although a link was discovered between cow’s milk and cancer rates, there was no suggestion of soy milk having the same effect.

“Greater Risk”

“No clear associations were found between soy products and breast cancer, independent of dairy,” revealed the findings.

“When compared to low or no milk consumption, higher intakes of dairy calories and dairy milk were associated with greater risk of breast cancer, independent of soy intake.”

    I understand it is the growth hormone in cow’s milk which contributes to the risk so as goat’s are not fed this can we safely drink goat’s milk ?
