Fertility Drugs Not Linked To Breast Cancer: Study


A new research contradicts with earlier study about link between fertility drugs and breast cancer.

Researchers of National Cancer Institute now says the fertility drugs has less probability of increasing breast cancer risk as earlier said.
Details of the study are published in the Cancer Epidemiology, Biomarkers & Prevention journal.

Fertility medication is given to those women who do not ovulate properly. The drug triggers egg production similar to how the hormones would do naturally.

The drug itself enables woman in getting pregnant. Sometimes it is also used along with assisted reproductive technologies (ART) like in vitro fertilization (IVF) and intrauterine insemination (IUI).

For quite some time it has been debated whether the fertility medications increase risk of breast cancer. Several studies say the link between the two is positive and the latest finding says the opposite. However, researchers of the new study says further investigation is required.

Chief of the Hormonal and Reproductive Epidemiology Branch at the National Cancer Institute (NCI), Louise A. Brinton said, “We wanted to evaluate the long-term relationship of fertility medications and breast cancer risk after controlling for other factors that have been shown to be correlated with both breast cancer risk and use of those drugs.”

For the study the researchers analyzed data of more than 12,000 women from five different US medical Institutions who were assessed for infertility between 1965 and 1988.

More than 9,000 women were included in the study and it was found only 749 of them developed breast cancer during follow-up.
