Hormone Contents in Oral Contraceptives are Carcinogens

From pro-choice website Livestrong: Types of Birth Control Pills & Their Hormone Doses

There are two main types of oral contraceptive birth control pills (OCPs): pills containing a combination of ethinyl estradiol (EE, a synthetic form of estrogen) and progestin (a synthetic form of progesterone), and pills containing only progestin. The method of action is different between the two types of OCPs. The contraceptive effect of combination pills is mainly due to estradiol blocking the release (ovulation) of an egg every month. Progesterone only pills work primarily by making the cervical mucous inhospitable to sperm and the uterine lining inhospitable to the embryo. Progestin-only pills are prescribed mainly for women who shouldn’t be exposed to elevated estrogen levels.

Now consider this:

PROGESTERONE is “Reasonably anticipated to be a human carcinogen” according to the United States’ National Institute of Environmental Health Sciences’ Report on Carcinogens.

ESTROGEN is “Known to be human carcinogen” according to the United States’ National Institute of Environmental Health Sciences’ Report on Carcinogens.

PROGESTIN is “Reasonably anticipated to be a human carcinogen” according to the United States’ National Institute of Environmental Health Sciences’ Report on Carcinogens.
