Drinking coffee regularly 'can slash prostate cancer risk in men'

A new study led by Harvard School of Public Health (HSPH) researchers has indicated that men who regularly drink coffee appear to have a lower risk of developing a lethal form of prostate cancer. The lower risk was evident among men who drank either regular or decaffeinated coffee.

"Few studies have specifically studied the association of coffee intake and the risk of lethal prostate cancer, the form of the disease that is the most critical to prevent. Our study is the largest to date to examine whether coffee could lower the risk of lethal prostate cancer," said senior author Lorelei Mucci, associate professor of epidemiology at HSPH.

Lethal prostate cancer is cancer that causes death or spreads to the bones.

"At present we lack an understanding of risk factors that can be changed or controlled to lower the risk of lethal prostate cancer. If our findings are validated, coffee could represent one modifiable factor that may lower the risk of developing the most harmful form of prostate cancer," said lead author Kathryn Wilson, a research fellow in epidemiology at HSPH.

The researchers chose to study coffee because it contains many beneficial compounds that act as antioxidants, reduce inflammation, and regulate insulin, all of which may influence prostate cancer.

The study is detailed in the Journal of the National Cancer Institute.
