Are there medications that can cause ovarian cancer? can certain kinds of medications actually cause ovarian cancer in some people?

No: If they are, they have been removed from the market by the fda.

None known: Since our knowledge of the etiology of ovarian cancer is incomplete i will never say never, but there are no drugs on the market that we know will cause ovarian cancer(would not be a good drug).

Possibly: There may be a slightly increased risk of a less aggressive type of ovarian tumor in women who have taken Clomid (clomiphene) for over one year for infertility especially of they did not have a child. However this is difficult to prove because never having a child is a risk factor for ovarian cancer itself. Long term use of make hormones or estrogen alone without Progesterone may also slightly increase risk.
