A new study reported online May 11 in Breast Cancer Research among almost 6000 Swedish women found that heavy coffee drinkers were far less likely to have an agressive form ( ER-Negative) of breast cancer. 5,929 Swedish women, aged 50 to 74, about half of whom had breast cancer,
completed questionnaires which were used to assess behavioral and health characteristics. Factors assessed included smoking and drinking patterns, physical activity routines, family history of breast cancer, hormone therapy protocols, nutritional intake, body mass index, education level and coffee consumption habits. In the women who had cancer, tumor status and breast cancer type were also noted.
The findings? Drinking coffee was linked to a "strong reduction" in risk for ER-negative breast cancer. Women who drank five cups of coffee a day had a 33 percent to 57 percent lower risk for ER-negative cancer than did those who drank less than one cup a day.
