Here’s some good news for men who enjoy a good cup of coffee: New research suggests there is a link between increased daily coffee intake and a lower risk of prostate cancer.

According to the American Cancer Society, prostate cancer affects about one in every eight men in the U.S. and is the second-leading cause of cancer deaths in the country.

Determining a relatively easy and accessible way to lower the risk of contracting the disease could be a gamechanger.

Researchers in China examined more than a dozen studies involving more than 1 million men that looked for possible links between coffee consumption and prostate cancer. Each participant reported how much coffee he drank, and the researchers found those who reported drinking the most had a 9% lower risk of prostate cancer when compared with those who drank the least amount.

Interestingly, they also determined that each single cup of coffee was associated with a 1% decrease in the risk of prostate cancer.

As for why coffee would have such health benefits, the researchers noted the brew improves glucose metabolism, has anti-inflammatory and antioxidant effects, and affects sex hormone levels, all of which play roles in developing prostate cancer.

The findings were considered significant because prostate cancer affects the lives of so many and coffee is such a popular worldwide drink. The studies, for instance, examined coffee and prostate cancer in men from Sweden to the U.S., from Japan to the United Kingdom.

So, guys, go ahead and get that free refill at the truck stop. It’ll do more than wake you up — it could save your life one day.
