Results from a decades-long study may enable women to drink coffee or tea without worry that doing so will increase their risk of developing breast cancer.
"Coffee and tea are remarkably safe beverages when used in moderation," said Dr. Davaasambuu Ganmaa of the Harvard School of Public Health in Boston.
Ganmaa and colleagues assessed coffee, tea and caffeine consumption among 85,987 women who participated in the Nurses' Health Study.
The women were between 30 and 55 years old at the start of the study.
Over 22 years of follow-up, 5,272 women developed breast cancer.
After accounting for other potential factors such as age, smoking status, physical activity, alcohol intake, family history, history of hormone therapy and number of children, the researchers found no elevated risk of breast cancer among women who reported drinking four or more cups of caffeinated or decaffeinated coffee or tea per day, compared with those who drank less than one cup daily.
They also found no apparent association between the occurrence of breast cancer and intakes of other caffeinated soft drinks and chocolate.
