10+ Year Significant Abortion-Breast-Cancer List


From 1 January 2008 to 1 October 2018 51 statistically significant

studies were published for the risk of breast cancer to women

with prior abortions. 98% of the 51 studies (i.e. 50) found that prior abortions raise breast cancer risk (1 study found reduced risk

(marked by '***')).

Armenia, Bangladesh, China, Central African Republic, France,

India, Iran, Iraq, Italy, Kazakhstan, Mexico, Pakistan, Sri Lanka,

Turkey, USA.








Note: For many of the ABC (Abortion-Breast-Cancer) studies

above, 'abortion' includes both induced abortions (IAs)

and spontaneous abortion (SAs (aka miscarriages)). Since

miscarriages, in general, pose lower breast cancer risk (via

delayed First Full-Term Pregnancy) than induced abortions,

any ABC study where subjects can have prior IAs or SAs

will UNDERESTIMATE the breast cancer risk due to

induced abortions. Despite that handicap, all but one of

those studies listed above achieved “statistical significance” (ie.

being at least 95% confident) for increased breast cancer risk.

(One (1) significant study reported reduced B.C. risk).
