Hm, you're right. I don't have any proof.
A board where people are looking for REAL information is a dangerous place to play operator.
Is there a link between the use of ovulation induction drugs and ovarian cancer?
In recent years, a multitude of studies have been published, attempting to find an association between the risk of ovarian cancer and environment factors, hereditary factors, and reproductive history. However, conclusive studies are scarce for a number of reasons. All examined associations appear to be weak, and the etiology of ovarian cancer appears to be multifactorial. This requires a large number of patients to reach any firm conclusion, and, based on the small number of ovarian cancers in the general population, it is difficult to find enough cases to demonstrate that a certain factor increases the risk of developing cancer.
Read that ENTIRE article. It cites (at least) a few studies. And FFS don't state something as fact (especially medical information) unless you can back it up.
Edit: And OP, I am so sorry for your loss. Monitoring should come with Clomid, and any RE/OB worth their salt should be able to provide you data about the limits they set for Clomid and why. I hope that you get some answers.
