Coffee and tea don't raise breast cancer risk

Results from a decades-long study may enable women to drink coffee or tea without worry that doing so will increase their risk for breast cancer, study findings suggest.

"In this large cohort of women, with 22 years of follow-up, we observed no association between coffee (caffeinated or decaffeinated) and tea consumption and the risk of breast cancer," Dr. Davaasambuu Ganmaa said.

"Coffee and tea are remarkably safe beverages when used in moderation," said Ganmaa, of the Harvard School of Public Health in Boston, Massachusetts.
