Coffee May Reduce Risks of Certain Breast Cancers

High daily intakes of coffee may significantly reduce a woman’s risks of anti-estrogen-resistant estrogen-receptor (ER-negative) breast cancer. Jingmei Li, from the Karolinska Institutet (Sweden), and colleagues assessed the association between coffee consumption and postmenopausal breast cancer risk in a large population-based study of nearly 6,000 people. The team reported that women who consumed five cups of coffee per day were 57% less likely to develop ER-negative breast cancer, as compared to a low consumption reference group. The researchers conclude that: “A high daily intake of coffee was found to be associated with a statistically significant decrease in ER-negative breast cancer among postmenopausal women.”
