Breast Cancer, Artificial Birth Control, and Procured Abortion

Breast Cancer - Artificial Contraception Links

A Case-Control Study of Oral Contraceptive Use and Incident Breast Cancer (2008)
"These results suggest that [oral contraceptive] use is associated with an increased risk of breast cancer diagnosed in recent years."
"After control for breast cancer risk factors, the multivariable odds ratio for 1 year or more of OC use, relative to less than 1 year of use, was 1.5[-fold]"

Risk Factors for Triple-Negative Breast Cancer in Women Under the Age of 45 Years (2009)

Study found that of a pool of women afflicted with breast cancer, artificial birth control use appears to be linked to a much greater incidence of a deadlier form of the cancer:
"Oral contraceptive use ≥1 year was associated with a 2.5-fold increased risk for triple-negative breast cancer...Furthermore, the risk among oral contraceptive users conferred by longer oral contraceptive duration and by more recent use was significantly greater for triple-negative breast cancer than non-triple-negative breast"

Effect of [injected] depo-medroxyprogesterone acetate on breast cancer risk among women 20-44 years of age"We found that recent DMPA use for 12 months or longer was associated with a 2.2-fold (95% CI: 1.2-4.2) increased risk of invasive breast cancer."

Breast Cancer - Procured Abortion Links

Women With a Previous Induced Abortion Had a Significant Increased Risk of Breast Cancer
Researchers led by Ai-Ren Jiang reported a statistically significant 1.52-fold elevation in risk for women with IAs [induced abortion] and a “significant dose-response relationship between (the risk) for breast cancer and number of (IAs),” meaning that risk climbed with number of IAs.

"The results support the inclusion of induced abortion among significant independent risk factors for breast cancer, regardless of parity or timing of abortion relative to the first term pregnancy. Although the increase in risk was relatively low, the high incidence of both breast cancer and induced abortion suggest a substantial impact of thousands of excess cases per year currently, and a potentially much greater impact in the next century, as the first cohort of women exposed to legal induced abortion continues to age."
