A meta-analysis published in the British Journal of Nutrition examined the relationship between egg consumption and the risk of hormone-related cancers, including breast, ovarian, and prostate cancers. The study found that consuming five or more eggs per week was associated with a modestly increased risk of breast cancer compared to no egg consumption. Similarly, a positive association was observed between egg intake and the risk of ovarian and fatal prostate cancers, though no significant link was found with total prostate cancer risk.
The potential mechanisms underlying these associations may involve the high cholesterol and choline content in eggs. Cholesterol serves as a precursor for sex hormones, which can promote cell proliferation in hormone-sensitive tissues, potentially contributing to carcinogenesis. Choline, essential for cell membrane synthesis, has been implicated in cancer progression due to its role in cell proliferation. While these findings suggest a possible link between high egg consumption and certain cancers, further research is necessary to establish causality and understand the underlying biological mechanisms.
