Effects of Controlled Ovarian Hyperstimulation (COH) With Letrozole and Gonadotropin in Women at High Risk for Breast Cancer
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.
