IVF on a natural cycle and cancer
The most important concern of women taking hormones for IVF is that these treatments can cause breast cancer.
It should be made clear that the drugs administered in IVF are hormones produced by the woman’s body itself, so they are not carcinogenic. They cause a transient increase in oestradiol levels produced by the ovaries for about 10 days.
All studies to date in the international literature, conducted over the last 25 years and in a sample of thousands of women, show that there is no additional risk for breast cancer from taking IVF medicines compared to women of similar age.
Also, studies show that women who undergo IVF because they are being followed by their gynecologist very often and have mammography (if they are> 35 years) before starting their attempts to become pregnant, if they present with breast cancer this is diagnosed at an early stage and are often cured.
