High daily intakes of coffee may significantly reduce the risks of certain types of breast cancer by about 60 per cent, according to new research.
Bringing new meaning to ‘5-a-day’
The study, published in Breast Cancer Research, suggests that drinking over five cups of coffee per day may significantly reduce the risks of developing a sub type of breast cancer known as anti-oestrogen-resistant oestrogen-receptor (ER-negative) breast cancer.
The team of Swedish researchers, based at the Karolinska Institutet, compared lifestyle factors including coffee consumption between women with breast cancer and age-matched women without, finding that coffee drinkers had a lower incidence of breast cancer than women who rarely drank coffee.
“We found no evidence that coffee consumption increases the overall risk of postmenopausal breast cancer. However, a high daily intake of coffee was found to be associated with a significant decrease in ER-negative breast cancer among postmenopausal women,” wrote the researchers, led by Jingmei Li.
The authors reported that five cups of coffee per day were 57 per cent less likely to develop ER-negative breast cancer than a low consumption reference group.
