Fish intake and ovarian cancer risk: a meta-analysis of 15 case-control and cohort studies.

ABSTRACT:

Background

Previous epidemiological studies have shown that fish consumption may modify the risk of ovarian cancer. However, these studies yielded controversial results. The present meta-analysis was undertaken to evaluate the relationship between fish intake and ovarian cancer risk.
