Breast Cancer Risk Reduced With Coffee

Lowering your risk of breast cancer may be as easy as drinking more coffee, according to a new study from Swedish researchers.

"Now, we don't have all the details," Dr. Per Hal, study co-author and professor of medical epidemiology and biostatistics at the Karolinska Institute in Stockholm, told HealthDay News."We don't know, for example, what specific type of coffee we're talking about here. But what we do know is that the protective effect is quite striking and remains even after adjusting for a lot of other factors that have the potential to play a protective role. And we know that we're talking about what we could call a relatively normal amount of coffee drinking. Certainly we're not talking about consuming gigantic amounts of coffee. So, this is a very intriguing finding."

Hal and a team of researchers from the Karalinska Institute analyzed data from over 5,900 Swedish women between the ages of 50 and 74, half of which had been diagnosed with breast cancer. The researchers asked each participant to fill out a survey with questions surrounding their general health and lifestyle choices, family history of breast cancer, tumor and breast cancer type (for those who had been diagnosed), highest education level achieved and the amount of coffee they drank.

They found that women who drank at least five cups of coffee a day were at a 33 to 57 percent lower risk of developing the most aggressive type of breast cancer known as ER-negative, which is a non-hormone-responsive disease. The researchers noted, however, that coffee did not reduce risks for developing ER-positive breast cancer, which is a hormone-responsive estrogen receptor. “There are one or two other studies that have pointed in the same direction as ours -- but not many, just a few," Hal said. "So before I would go to tell my neighbors to start drinking more coffee than they already do, I would like to know what is the biological mechanism at work here. And that's not yet clear." The researchers, who published their study in the online edition of the Breast Cancer Research journal, are already hard at work on a new study to help them come to a more clear understanding as to why coffee is linked to lower risks for this type of breast cancer.
