Health experts carried out a two-year study of 1,000 women with an average age of 59.
Half were diagnosed with ovarian cancer while 500 were free of the disease.
The researchers discovered that those women without cancer were more likely to be tea drinkers from an earlier age than those diagnosed with the illness, the Daily Express reported.
Flavonoids, powerful compounds with strong disease-fighting properties, were found in black tea in particular, according to the study at the School of Public Health, Curtin University in Perth, Australia.
“Tea consumption should be encouraged because of the potential benefit in preventing this common and deadly disease,” study co-author Dr Andy Lee said.
Ovarian cancer affects around 7,000 women a year in the UK.
