Effects of Controlled Ovarian Hyperstimulation (COH) With Letrozole and Gonadotropin

Completed

Conditions studied: Infertility, Breast Cancer

In brief

Fertility drugs have the effect of increasing hormone levels. Higher hormone levels from infertility treatments may increase breast cancer risk, but there has not been enough research to know for sure. Researchers want to use a method of taking breast tissue cells from women who are having infertility treatment. The breast tissue cells might show changes that would indicate an increased risk of cancer. The method of taking the breast tissue cells is called Fine Needle Aspiration (FNA). The purpose of this study is to examine the changes in breast tissue, in women at high risk of breast cancer who are being treated with controlled ovarian hyperstimulation.
