Coffee consumption and breast, ovary and endometrial cancers – Part 1

Print this page

This is the fifth of six blog posts on the topic of coffee consumption and cancer research, concentrating on the impact of coffee consumption and breast, ovary and endometrial cancers. Coffee and Health also houses current scientific information on a wide range of other coffee-related topics.

Following is an overview of research conducted in this area.

Coffee drinking linked to lower risk of breast cancer in pre-menopausal women

A meta-analysis and a French study both find that coffee consumption is not linked to an increased risk of breast cancer overall.

Research shows no association between coffee consumption and the occurrence of breast cancer in post-menopausal women.

In pre-menopausal women, studies show the regular consumption of coffee (4 cups a day) is associated with a 38% lower risk of breast cancer.

In women at high risk, because of genetic variations (i.e. they carry the BRCA1 and BRCA2 mutation), the risk for breast cancer falls by 25-70% with daily consumption of 4-6 cups of coffee compared with non-coffee drinkers.

Evidence from a further study of specific cells highlights the importance of taking individual genetic variability into account when assessing diet-disease associations, as it finds a 64% reduced risk of breast cancer in only one specific genotype.

More research is needed to clarify the link between coffee and breast cancer risk in pre-menopausal women.
