Ovarian Cancer Risk Unaffected by Tea

Meta-analysis of published studies finds no decreased risk in tea drinkers

WEDNESDAY, Dec. 19 (HealthDay News) -- Drinking tea appears to have no effect on the risk of ovarian cancer, according to a meta-analysis in the December issue of the Amercian Journal of Obstetrics & Gynecology.

Bo Zhou, M.D., from Nanjing Medical University in China, and colleagues pooled the results of nine published studies (two cohort and seven case-control studies) examining the association between tea intake and ovarian cancer risk.

The researchers found that tea consumption was not associated with reduced ovarian cancer risk (combined relative risk 0.84). Study design (after stratifying into subgroups) had no substantial effect on the result, while a sensitivity analysis showed the results were stable.

"Our findings did not support that tea consumption was related to the decreased risk of ovarian cancer," Zhou and colleagues conclude.
