“Results: During 1,246,967 person-years of follow-up, 1,344 cases of invasive breast cancer were diagnosed. Past use of any oral contraceptive was not related to breast cancer risk [multivariate relative risk (RR), 1.12; 95% confidence interval 0.95-1.33]. Current use of any oral contraceptive was related to a marginally significant higher risk (multivariate RR, 1.33; 95% CI, 1.03-1.73). One specific formulation substantially accounted for the excess risk: the RR for current use of triphasic preparations with levonorgestrel as the progestin was 3.05 (95% CI, 2.00-4.66; P < 0.0001).”
About 1 out of 1000 women in this study developed breast cancer and past use of birth control was not related to breast cancer risk. Current use was slightly related but it was one specific birth control that accounted for excess risk.
So if 1 out of every 1000 women in the study got breast cancer, and current use of birth control only accounted for a small increase of risk, how many women out of that 1.25 million could really attribute their breast cancer to birth control? Certainly not very many…and it looks like one specific formula was basically the sole culprit.
And where is your science? Please don’t cite some Catholic website or lifesitenews or something ridiculous.
