More Research Shows Support for Abortion Breast Cancer Link


This winter, two studies appearing in public health journals provided strong statistical support for the abortion breast cancer link. In December the journal Cancer Causes Control published a meta-study analyzing the link between abortion and breast cancer in China. Chinese public health data has the ability to offer some important insights about the abortion-breast cancer link. That is because the institution of the one-child-per-family policy in the early 1980s increased the number of abortions performed in China.

Overall this study provides very strong evidence that abortion increases the risk of breast cancer. Thirty-one of the 36 studies included in the meta-study showed a positive correlation between abortion and breast cancer. For at least 19 studies, the correlation achieved conventional standards of statistical significance. These findings held for studies with different methodological approaches. They also held for research done in different Chinese provinces. The study also adds to a body of research which finds that the risk of breast cancer increases as the number of induced abortions increases.

Also in December, the Indian Journal of Cancer published a study which analyzed 300 Indian women who had breast cancer. The study compared these women to a control group with similar demographic characteristics. Like many studies analyzing the incidence of breast cancer — this study found that a family history of breast cancer, a lower duration of breast feeding, and a higher use of oral contraceptives all increase the risk of breast cancer. However, holding these factors constant, this study found that abortion also significantly raised the risk of breast cancer. In fact, abortion was one of the strongest risk factors — increasing the risk of breast cancer by a whopping 626 percent.

Both the mainstream media and academics do their best to ignore credible public health research showing an abortion breast cancer link. In fact, neither the Chinese study nor the Indian study have received any serious attention from the mainstream media. That having been said, academic studies demonstrating the link between abortion and breast cancer date back to the 1950s. Furthermore the fact that solid research is emerging from foreign countries – some of whom have seen a sharp increase the incidence of abortion – may force the media, public health professionals, and academic researchers to take notice.
