We’ve written about the many health benefits of coffee before — but it seems there’s an exciting new one for women to add to the list: cancer-prevention.

A new study has found that moderate to heavy coffee consumption (specifically, four or more cups a day) can lead to a 22% lower risk of endometrial cancer, compared to non-coffee drinkers.

Though many of us might not have heard of endometrial cancer, it is actually the most common type of gynecological cancer. Eek! If that’s not a reason to start drinking some cups of joe, I don’t know what is. (And to think Luke gave Lorelai such a hard time for her incessant coffee drinking!)

According to Harvard Medical School research fellow and the study’s lead author Dr. Marta Crous-Bou, the results show that there is an association between coffee intake and lower endometrial cancer risk. As she told Live Science, the researchers found that drinking coffee can protect people from developing this type of cancer!

Researchers looked at 19 similar studies, which included about 40,00 women — 12,o00 who had already been diagnosed with endometrial cancer — to determine the effects of coffee consumption on a woman’s risk of developing endometrial cancer. It is important to note that the study also found that the positive effects of drinking coffee are only associated with women whose BMI identifies them as overweight or obese– a high BMI already leads to an increased chance of getting this type of cancer. According to Crous-Bou, while drinking four cups or more of coffee a day provided the greatest cancer risk reduction, women who drank two or three cups of coffee had a still had a seven percent lower risk than those who drank none. Someone should tell the tea drinkers immediately!

While these findings have yet to be published in a peer-review journal and the study didn’t look at what made coffee so helpful, Crous-Bou’s researchers believe that certain compounds in coffee may decrease levels of estrogen and insulin. According to Crous-Bou, both estrogen and insulin have been shown to play a role in the development of endometrial cancer.

So, for those of you who, like many of us, are given a hard time for your incessant coffee consumption, rest assured! The positive effects of coffee are becoming more and more known.
