Coffee May Reduce Breast Cancer Risk

The best part of waking up... is actually waking up.

Although certain studies have demonized coffee, a recent study conducted at the Karolinska Instituet in Sweden has shown a link between drinking coffee and a reduced risk of breast cancer. More specifically, coffee appeared to reduce the rate of antiestrogen-resistant estrogen-receptor (ER)-negative breast cancer. Interestingly, the same effect was not found in ER-positive breast cancer.

The difference between ER-positive and ER-negative breast cancer is that ER-positive tumors have estrogen receptors on their cell surfaces, meaning that the tumor is sensitive to systemic estrogen levels. We were wondering if the sensitive tumors cried during Terms of Endearment too... but we didn't want to look like a-holes for asking.

Researchers controlled for lifestyle factors that affected breast cancer, such as weight, family history of breast cancer, and age at menopause. They found that women who drank coffee had a lower rate of developing ER-negative breast cancer than women who rarely drank coffee. The researchers, however, could not determine precisely how coffee serves as a protective agent against ER-negative breast cancer.

Studies conducted in other areas of the world have not shown the same correlations, which the researchers suggest is a result of differing types of coffee or styles of coffee preparation.

You always knew coffee could save your ass in the morning--looks like other body parts may be benefiting as well.
