Coffee May Slash Risk of Certain Breast Cancers
New research shows that drinking coffee may significantly reduce the risk of certain breast cancers. The study was conducted by researchers at Karolinska Institutet in Sweden.
Their findings were published in the May 2011 issue of the journal Breast Cancer Research.
For the study the researchers looked into the association between coffee and post-menopausal breast cancer among nearly 6,000 study participants.
Overall, the researchers observed a “modest” reduction in breast cancer risk. However, when the researchers divided the participants into groups based on the type of breast cancer they found that heavy coffee drinkers had a 60% reduction in ER-negative breast cancer. Heavy coffee drinkers were classified as those who drank 5 or more cups per day.
Some breast cancers are fueled by the female hormones estrogen and progesterone. ER-negative breast cancer, however, does not rely on hormones for growth. It also does not respond to hormone-based therapy.
This is not the first study to look into the health benefits related to coffee. These benefits are generally attributed to the powerful antioxidants found in coffee called polyphenols and include reducing the risk of developing diabetes, prostate cancer, cirrhosis and oral cavities.
Over half a dozen different studies have also shown that people who drink coffee regularly are up to 80% less likely to develop Parkinson’s disease.
