Abortion and Breast Cancer: Any Link?

Analysis of more than 30,000 breast cancer cases finds no increased risk of breast cancer following induced abortion or miscarriage

1

Induced abortion and miscarriage do not increase breast cancer risk, according to a Finnish registry-based case-control study.
2

The study analyzed data from 31,687 breast cancer patients and 158,433 matched controls, providing high-quality evidence.
3

No significant variation in breast cancer risk was found based on the number of abortions or miscarriages or age at first occurrence.
4

A slight increase in postmenopausal breast cancer risk was noted for women whose first abortion was before age 20, but this may be coincidental.
5

The findings counter ongoing misinformation about abortion and breast cancer risk, supporting clinical counseling reassurance.
