Fertility Drugs Does Not Increase Risk of Breast Cancer!
Research conducted by the National Cancer Institute in Bethesda, Maryland, United States denied it. They conducted a study of nearly 10,000 women taking fertility drugs and monitored them for 30 years. The results of the study were then compared with the risk of cancer in women who do not take fertility drugs.
From the study it was known that 38 percent of participants used Clomiphene medication while another 10 percent used gonadotropins. The report did not explain about the use of other drugs. Of the 9,892 women examined in 1965 to 1988, there were 749 cases of breast cancer.
This suggests that there is no relationship between fertility drug use with breast cancer risk. Dr. Louise Brinton who is the head of the Hormonal and Reproductive Epidemiology from the National Cancer Institute said that the results of this study is very soothing.
“Concerns arise because these drugs can increase the percentage of ovulation that increase levels of estrogen in the body. This is said to increase the risk of breast cancer,” said Brinton to Reuters
Dr. Kurt Barnhart, president of the Society for Reproductive Endocrinology and Infertility say that the findings of this study may be support women who are pregnant but are afraid to follow the fertility treatment because of the risk of breast cancer.
“With this study it is certain that women who are infertile and want to take medication can do so without having to fear the risk of breast cancer,” said Dr. Barnhart.
Even so , Brinton asserts that this study is not meant to trivialize the importance of breast cancer screening. He added that the participants in this study was 50 years of age, the age at which breast cancer symptoms first appears. In a previous research it was also known that IVF does not increase the risk of breast cancer.
