Tea, coffee don't increase breast cancer risk, study says

Researchers at Harvard School of Public Health in Boston say a 22-year long study shows no association between coffee and tea consumption and the risk of breast cancer.

Doctors studied 86,000 women aged 30 to 55. Over 22 years of follow up, 5,000 women developed breast cancer. After accounting for risk factors such as age, smoking status, body mass, physical activity, family history, menopausal status and hormone therapy, they found no increased risk of breast cancer among women who drank four or more cups of coffee or tea daily.

The study is in the International Journal of Cancer.
