International medical insurance customers might want to discuss the risks of breast cancer with their doctor.
According to recent research, drinking coffee could reduce the likelihood of developing the disease, but there are a number of other factors involved.
The study from the Karolinska Institutet found that among age-matched, healthy women, those who drank coffee were less likely to have breast cancer.
But after adjusting the data to account for other risk factors, such as exercise and weight, the team found that the protective effects of coffee were only measurable for estrogen-receptor-negative breast cancer.
The leader of the study, Dr Jingmei Li, 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."
