A study published in the Indian Journal of Community Medicine (May, 2013) found a 6.38-fold greater risk of breast cancer among Indian women with histories of induced abortion.
Study leader Ramchandra Kamath of the Department of Public Health, Manipal University, observed that India has the “largest estimated number of breast cancer deaths worldwide,” and that breast cancer ranks second only to cervical cancer as the most common diagnosed malignancy among Indian women.
Although the study cohort included only 188 participants (94 cases and 94 controls), which the researchers acknowledged limited the “generalisability of the findings,” U.S. expert Dr. Joel Brind said the small study does strongly reconfirm that higher rates of abortion lead to increased risk of breast cancer.
“With only 94 cases and 94 controls, the study was way too small for a significant risk of the order of 1.5-fold to even show up,” said Professor Brind in a statement to the Coalition on Abortion/Breast Cancer. “Yet induced abortion did show up as the strongest risk factor (and right on the border of statistical significance) because the risk increase was so high at 6.38-fold.”
Dr. Brind is a professor of endocrinology at Baruch College, City University of New York and a recognized expert in research into the links between abortion/contraception and breast cancer.
Dr. Brind said he found it “troubling that the abortion-breast cancer link is now showing up big time in the world’s most populous countries where breast cancer used to be rare.
