Los anticonceptivos y el aborto provocan cáncer de mama

11 de junio de 2012 a las 17:50

Acaba de salir un nuevo estudio en el n de 25 de abril 2012 de la revista Cancer Research, que revela un aumento del riesgo de cáncer de mama de 2.2 en las usuarias del anticonceptivo Depo-Provera.

Igualmente, también la píldora anticonceptiva tiene este efecto abortígeno: (min. 11:10, etc.)... para no hablar de la del Día Después (PDD), que es 20 veces más potente que "La Píldora".

El aborto, por su parte, es el mayor factor de riesgo del cáncer de mama, como puede verse (en español) en

Study: Recent Depo Provera Use Increases Invasive Breast Cancer Risk 2.2-fold When Used 12 Months or More

The Coalition on Abortion/Breast Cancer notes a study of 1,028 women ages 20-44 in the April 15, 2012 issue of Cancer Research found that recent users of depo provera (DMPA) for 12 months or more had a statistically significant 2.2-fold increased risk of developing invasive breast cancer. [1] The authors, Christopher Li and his team (including Janet Daling) at the Fred Hutchinson Cancer Research Center called it the first large scale U.S. study examining the link between DMPA and breast cancer. They concluded its the fifth study conducted over a diverse group of countries that have observed that recent DMPA use is associated with a 1.5- to 2.3-fold increased risk of breast cancer. [2]

Lis team said the 2003 Womens Health Initiative study of hormone replacement therapy (HRT) strongly suggest that agents containing progestin, medroxyprogesterone acetate (MPA), in particular, increase a womans risk of breast cancer. MPA combined with estrogen raised risk by 24%, while estrogen only replacement therapy had a nonstatistically significant reduced risk. [3]

Like cancer-causing oral contraceptives (the pill) and combined (estrogen + progestin) HRT, the DMPA-breast cancer link supports an abortion-breast cancer link. Estrogen in the presence of progesterone (i.e. progestin) stimulates the growth of cancer-susceptible Type 1 and 2 breast lobules.

In the case of DMPA or any other progestin-only pill, the estrogen component is provided by the womans own ovarian estrogen, reported Joel Brind, professor of human biology and endocrinology at Baruch College, City University of New York.

Karen Malec, president of the Coalition on Abortion/Breast Cancer, added:

In implementing Obamacare, the federal government will require employers to purchase insurance that provides women free abortifacients, contraceptives and sterilizations, including DMPA. Why offer free drugs that damage womens health, but not free life-saving drugs? Thats the perfect definition of a war on women!

Cancer groups should have implemented a nationwide awareness campaign about the DMPA-breast cancer link, but its no surprise they didnt. Theyve lied to women about the risks of abortion, oral contraceptives and combined hormone replacement therapy for decades. They still havent reported that two studies since 2009 strongly linked oral contraceptive use with the deadly triple-negative breast cancer. [4,5]
The Coalition on Abortion/Breast Cancer is an international womens organization founded to protect the health and save the lives of women by educating and providing information on abortion as a risk factor for breast cancer.
