Can an induced abortion contribute to breast cancer risk?

The verdict: It’s possible.

In conclusion, despite several limitations, we have demonstrated that IA might increase the risk of breast cancer in parous women, but in the nulliparous, IA was not observed to be significantly associated with an increased risk of breast cancer. We did not observe any association between breast cancer risk and the times of IAs. The specific association between breast cancer and the 1st age of IA would require more high quality and detailed studies for further verification.

What does that mean for you?
Simple:
If you have had an abortion and already have successfully given birth at least once, get regular check-ups.
