Breast cancer is a type of cancer that forms in the cells of the breast tissue. It occurs when normal breast cells undergo uncontrolled growth and division, leading to the formation of a malignant tumour, which can be life-threatening. In this article, we will discuss whether IVF causes breast cancer. We will also examine the relationship between IVF and breast cancer.
Is there an association between breast cancer and IVF?
Maybe. There is some evidence that suggests that IVF may increase the risk of breast cancer. However, the research is still ongoing and the results are still not conclusive.
One study found that women who started IVF after the age of 30 appeared to be at an increased risk of developing breast cancer. Additionally, another study also found that the characteristics of breast tumours in women who underwent IVF were no different than in patients without previous exposure to IVF.
However, cancer.net compiled 30 researches and found no significant increase in breast cancer risk or decrease in risk following infertility treatment, when compared to women who did not have treatment or the general population,
In conclusion, current research on the association between breast cancer and IVF is still limited. Further research is needed to determine whether there is a true association between the two and, if so, what the mechanism is.
What can be the possible reasons for this association between IVF and breast cancer?
The possible reasons for an association between breast cancer and IVF are as follows:
- Hormonal exposure. IVF involves exposure to high levels of hormones, such as estrogen. Prolonged exposure to such hormones can stimulate the growth of breast cells, which could increase the risk of breast cancer.
- Age. In general, women who undergo IVF are often older than women who conceive naturally. Older women are at an increased risk of breast cancer.
- Genetics. Women who have a family history of breast cancer may be at an increased risk of developing the disease, regardless of whether they have undergone IVF.
It must be noted that the above-mentioned might be the probable cause and are not definitive. Further research is needed on this. You must consult a doctor if you are concerned about the risk of breast cancer after IVF as they can help you assess your risk and recommend ways to reduce it.
