There?s long been debate over fertility drugs and if they could increase a woman?s risk for breast cancer. A new study says ?yes,? but only in some cases.

Hormones are known to play an important role in breast cancer. So could the hormones given during fertility treatments cause a problem?

A?study in the Journal of the National Cancer Institute tried to determine the risk of breast cancer in younger women whose used fertility drugs to stimulate their ovaries to produce more estrogen.

The authors looked at some 14?hundred pairs of sisters, Some who got breast cancer under age 50 and some who didn?t. They found that women who used fertility drugs resulting in pregnancies that didn?t last for more than ten weeks had a decreased risk of breast cancer.

But those who used fertility drugs and had a 10?weeks?or?longer pregnancy showed a small increased risk of breast cancer.

The authors say this may be because elevated production of ovarian hormones early in pregnancy could alter the normal changes in breast tissue that come with pregnancy.

So what should you do if you?re considering fertility treatments? Talk to your doctor about the possibility of heighten screening for breast cancer.
