Research Review Finds that Dairy Consumption is Not Associated with an Increased Risk of Breast Cancer


The most fatal cancer in women is breast cancer and it has now overtaken lung cancer as the world’s most diagnosed cancer. A woman is diagnosed with breast cancer every 14 seconds. Investigations on the association between food and breast cancer has been undertaken and research has shown that higher intakes of dairy milk may be associated with a higher risk of breast cancer, however it is largely undefined and unclear. The main goal of this research was to systematically review research from 2008 to 2022 that looked at the association between dairy products and breast cancer development. After reviewing 18 studies, the results showed that dairy consumption was inversely associated with the risk of developing breast cancer, meaning that as dairy consumption increased, the risk of breast cancer decreased. Despite there being several theories linking milk consumption and breast cancer, there is no strong correlation evident in the literature at this current date.

Background: Among the world, the most frequently discovered and fatal cancer in women is breast cancer (BC). From the perspective of public health, estimating the BC risk linked to dairy intake may aid in comprehensive management. In epidemiological research data on the association between eating dairy foods and the risk of BC are conflicting. Therefore, we sought to assess the link between dairy food consumption and the development of BC. Main text: To summarize and quantify the most recent findings on consuming milk or other dairy foods and the development of BC, we performed a systematic literature review. We checked through several databases for relevant publications published in English up to January 2022. Of the 82 articles identified, only 18 met the inclusion criteria and were analyzed. Nine Prospective, seven Retrospective and two Cross-Sectional studies were finally identified. Conclusions: Overall, dairy consumption was inversely associated with the risk of developing breast cancer. Future studies will help elucidate the role of dairy products in human health, and their use within a balanced diet should be considered.
