Professor Joel Brind and his colleagues reported a "30% greater chance of developing breast cancer" in their 1996 review and meta-analysis of worldwide data.  

Brind said recently:  

"If we take the overall risk of breast cancer among women to be about 10% (not counting abortion), and raise it by the 30%, we get a 13% lifetime risk.

"Using the 50 million abortions since Roe v. Wade figure, we get 1.5 million excess cases of breast cancer.

"At an average mortality of 20% since 1973, that would mean that legal abortion has resulted in some 300,000 additional deaths due to breast cancer since Roe v. Wade."

Brind said his estimate excludes deaths from the use of abortion to delay first full term pregnancies - a recognized breast cancer risk.
