Hey friends! So, I came across some interesting news that I just had to share with you. A recent study from the Netherlands has shown that there’s no connection between in vitro fertilization (IVF) and an increased risk of breast cancer. Can you believe that? After a long-term follow-up, researchers found that women who underwent IVF had breast cancer rates similar to those in the general population.
In the past, some studies hinted that IVF might lead to a higher risk of breast cancer, but those findings were not very conclusive, mainly due to limited follow-up periods. That’s why this Dutch team stepped up to investigate the long-term breast cancer risk after women went through ovarian stimulation for IVF.
They gathered data from over 19,000 women who started IVF between 1983 and 1995, alongside nearly 6,000 women who opted for other fertility treatments during the same time frame. After an impressive median follow-up of more than 21 years, it turned out that the breast cancer incidence was practically the same between the IVF group and the non-IVF group. For instance, by age 55, the breast cancer rates were 3.0% among the IVF ladies compared to 2.9% in the others. That’s pretty reassuring!
Interestingly, women who underwent seven or more IVF cycles actually had a lower risk of breast cancer compared to those who had just one or two cycles. It seems that the hormonal exposure during IVF could be somewhat protective, similar to how pregnancy hormones help lower breast cancer risk.
However, there was a caveat: women who had previously given birth faced a higher risk than those who hadn’t. Also, first-time mothers at age 40 were found to be twice as likely to develop breast cancer compared to younger moms. It’s a complex topic, but this study provides some much-needed clarity.
