Drinking coffee could help to protect women against developing breast cancer.
This is according to recent research from the Karolinska Instiutet, which looked at age-matched healthy women.
They found that those drank coffee regularly had a lower incidence of breast cancer than those who rarely enjoyed the beverage.
However, once the information was adjusted to account for other possible risk factors, such as weight and the menopause, the researchers found that the protective effect of coffee was only measurable for estrogen-receptor-negative breast cancer.
Meanwhile, a team from Germany found the same trend but with a much weaker emphasis on this area of the cancer.
Dr Jingmei Li, who led the research, commented: "We can not say which mechanism lies behind the beneficial effect of coffee yet.
"It is unlikely that the protective effect is due to phytoestrogens present in coffee since there was no reduction in the incidence of ER-positive cancer, that is, hormone dependent cancer, in this study."
