Black Tea and Ovarian Cancer Risk

In a hospital-based study involving 414 women with cancer, it was found
that women who drank 2 of more cups of black tea had a 30% reduced risk
of ovarian cancer. Consuming 2 or more cups of decaffeinated coffee has
had nearly a 30% reduction in risk (29%, actually). No protective effect
could be found for women who drank caffeinated coffee.
