NOTE FROM THE COALITION: The latest tactic for the abortion-breast cancer scientists who are trying to politicize their findings is to write misleading abstracts and to publish studies that are too small to implicate induced abortion as a risk factor for breast cancer. While it does not say so, the Marcus study is the twelfth American study to implicate induced abortion as a risk factor for breast cancer, showing a risk increase of 20%. It is the thirteenth U.S. study to publish data on the abortion-breast cancer link. See Dr. Joel Brind's Fall, 1999 issue of the Abortion-Breast Cancer Quarterly Update for his commentary. ("New NCI Study Finds -- But Covers Up -- ABC Link in North Carolina Women," p. 3).

ABSTRACT:

OBJECTIVES:
This study investigated the relationship between reproductive events during adolescence and subsequent breast cancer risk. METHODS: Logistic regression models used self-reported data from 862 case patients and 790 controls in the Carolina Breast Cancer Study. RESULTS: Miscarriage, induced abortion, and full-term pregnancy before 20 years of age were not associated with breast cancer. Among premenopausal women, breast-feeding before 20 years of age was inversely associated with disease. Oral contraceptive use before 18 years of age was positively associated with disease risk among African American women only. CONCLUSIONS: Pregnancy during adolescence does not appear to influence breast cancer risk, but breast-feeding may. A possible increased breast cancer risk among African American women who used oral contraceptives as adolescents warrants further study.
