“Women who have had breast cancer and who therefore need to limit their exposure to estrogen have an interest in stopping consuming whole milk-based dairy products and instead prefer low-fat dairy products.” This is the conclusion of a study conducted by Dr. Candyce Kroenke of Oakland, Calif. Among 1,900 women who have survived breast cancer. A study that she has been leading for 15 years and which has just been published in the Journal of the National Cancer Institute.
At the end of these fifteen years of follow-up, Dr Kroenke affirms that women who have survived breast cancer who consume one or two whole milk-based products each day (whole milk, cheese, ice cream, etc.) have a 49% higher risk of dying from their cancer than those who consume low-fat products. A total of 372 women died during these years of follow-up and 189 died from a recurrence of their breast cancer.

Dr Kroenke explains that he was interested in whole milk-based dairy products because they contain more estrogen (found in fat) than low-fat products. However, we know that estrogens promote the development of certain breast cancers. But the doctor recognizes that further studies must now be carried out to establish the link between the consumption of products rich in fat and their possible influence on the different types of breast cancer: cancer with positive estrogen receptors (ER-positive ) or negative estrogen receptors.
“It should also be noted that some women in this group died, not as a result of their cancer, but of cardiovascular disease. However, a diet rich in fat is always an additional risk factor for cardiovascular disease, ”adds Dr Kroenke.
