[Association between endometriosis and ovarian cancer].

The objective of this study was to review the literature concerning the possible link between endometriosis and ovarian cancer, and to highlight common aetiological factors. The aetiology for both diseases seems to be multifactorial. Hormonal, genetic and immunologic factors seem to play a role. With a twofold increased risk of developing ovarian cancer in patients with endometriosis in general and a further fourfold increased risk for high risk endometriosis patients with infertility, the findings seem relevant and should be kept in mind when encountering and treating patients with endometriosis.
