I am sad to say that American Cancer Society gives money to Planned Parenthood. I don't know why many cancer fighting organizations give to a an organization that offers high-dose hormonal contraception containing dangerous carcinogenic chemicals. In fact, the American Cancer Society itself lists oral contraceptives as increasing a woman’s risk of breast cancer by 24%, while a 2006 report in the journal of the Mayo Clinic found a risk factor increase of 44% for pre-menopausal breast cancer in woman. In 2005, The World Health Organization (WHO) listed hormonal contraceptives as carcinogenic and confirmed they increased the risk of breast, cervical, and liver cancer in women.
