A woman’s risk of developing aggressive triple negative breast cancer seems to increase 4- fold for individuals who are either taking birth control drugs or are taking the breast cancer drug, Tamoxifen.
Both pieces of research out of the Seattle- based Fred Hutchinson Cancer Research Center and published in different scientific journals in 2009, include important facts for women who are currently using either of these drugs, or considering the use of either drug.
Unfortunately neither the American Cancer Society, nor Susan G. Komen for the Cure have yet to mention either of these recent and alarming studies on their websites as of May 7, 2010.
If the American Cancer Society is considered by many to be our unofficial national cancer prevention organization ; if Susan G Komen is considered to be our leading national non profit on breast cancer education, why isn’t either group sounding an alarm about using birth control drugs or using Tamoxifen?
A possible answer: Pharmaceutical companies that make billions from contraceptive drugs and billions from the sale of Tamoxifen, also give hundreds of millions to the American Cancer Society and to Komen each year. Perhaps, these non-profits are unwilling to bite the hands that feed them.
Meanwhile, American women are left vulnerable for developing triple negative breast cancer as this fast growing type of breast disease is now rapidly increasing across the United States.
Triple Negative now represents 15% to 20% of all new invasive breast cancer diagnoses, striking younger women more often than older women and striking a disproportionate number of younger black women compared to white women.
