Does medical abortion increase the risk of breast cancer?

No, having an induced abortion does not increase a woman’s chance of developing breast cancer.

More scientific information:

“Abortion does not increase a woman’s risk for cancer. Flawed epidemiologic studies led to claims that abortion elevates a woman’s risk for breast cancer in later life. …After review of the evidence, both the World Health Organization and the National Cancer Institute in the Unites States have concurred that no credible evidence supports a link between abortion and breast cancer".30
