Fertilization invitro does not increase cancer risk

According to a Swedish study, revealed in the magazine Human Reproduction, the in vitro fertilization (IVF) would not be related to an increase in cancer risk despite the hormones used, against the classic idea that it was thought that the drugs used for fertility could be linked to cancers of the breast, uterus and ovaries.

At the University of Lund in Sweden, they analyzed the data of 24 thousand women between 1982 and 2006 who gave birth after IVF. The specialists compared cancer rates in these women with those of 1.4 million women in the Swedish general population who also had children in those years.

As a result, less than 2% of female patients in the IVF group developed one or more cancers during the following 8 years, compared with almost 5% in the control cohort.

Taking into account maternal age, the number of previous pregnancies and smoking, the risk general cancer was around 25% lower among women treated with invitro fertilization.

"A partner who needs IVF do not should have fear that him hormonal treatment used - at least those used in Sweden - pose a risk for women to develop cancer, "said Bengt Kallen of Lund University to Reuters Health.

Among the results, he highlighted that the risk of ovarian cancer is more than double in the female patients of IVF compared to those who do not. In this regard Kallen noted that this is due to abnormalities in the ovarian function that just as they could increase the risk of both cancer, they also increase the possibility of infertility, hence the need for IVF.

"The risk of two common cancers, breast and uterine, was significantly lower than expected," the expert added.

The author said that this is because women who undergo IVF may be healthier in other ways or, more likely, have more cervical and mammographic controls.
