Pill Causes Triple Negative Breast Cancer

The use of oral contraceptives has been found to have a significant association with the development of an often fatal form of breast cancer. This is according to a report published in the April 2009 issue of Cancer, Epidemiology, Biomarkers and Prevention, a leading cancer journal. These results present a new challenge to scientists in the field of breast cancer research.

I did find this in the comments of an article:

 Birth Control Pill Linked with Triple Negative Breast Cancer
posted by Karen Malec on 9 Nov 2011 at 7:46 am

Two studies have linked use of the birth control pill (oral contraceptives) with triple-negative breast cancer. The studies are Jessica Dolle et al. 2009 (Cancer Epidemiology Biomarkers and Prevention) and Huiyan Ma et al. 2010 (Cancer Research).

Dolle's team found that recent users of the pill within the last 1-5 years multiplied their risk of TNBC by 4.2 times. National Cancer Institute branch chief Louise Brinton was a co-author in this study.

Ma's team found a "2.9-fold increased risk of TNBC tumors among older women (age 45-64) who started OC use (use of the pill) before age 18."

The hormones in the pill can be delivered through different means, i.e. orally and by injection, skin patch, vaginal ring, IUD.

Some prescription drugs can increase ER-/PR-/HER2- risk

Use of selective serotonin reuptake inhibitors (SSRIs) such as Paxil and Prozac are suspected of increasing risk of (ER-/PR-) breast cancer in older women. Use of birth control pills has been found to be associated with risk of triple negative breast cancer in younger women.
