Endometrial cancer is the most common uterine cancer and research has shown that women who drink 4 or more cups of coffee per day are at reduced risk of endometrial cancer.
When researchers followed dietary details, lifestyle information and medical history of 67,470 women aged 34-59 from the start of the study in 1980 till 2006; they found that compared with women who drank less than 1 cup of coffee a day, those who drank 4 or more cups had a 25% lower risk of endometrial cancer. Participants who drank 2 or more cups of decaffeinated coffee per day had a 22% lower risk of endometrial cancer.
Lead author, Youjin Je said, "For healthy non-pregnant women, drinking four cups of coffee a day has no known negative effects. But, a substantial amount of sugar, cream or milk added to coffee can negate the potential benefits."
The study has been published online recently in Cancer Epidemiology, Biomarkers & Prevention.
