Birth control pills increase risk of breast cancer
Birth control pills as Group 1 carcinogen
The World Health Organization officially labels combined oral contraceptives as a Group 1 Carcinogen, on the same list as other more publicised causes of cancer such as asbestos, tobacco, and tanning booths. Yet, the medical community continues to prescribe the birth control pill for everything from acne to mood swings, with the thought that the benefits outweigh the risks. At Lady-Comp, we urge you to ask questions and be informed of all of your options before starting a regimen of hormonal contraceptives.
World Health Organization (WHO) research summary
According to the World Health Organization, years of scientific research data has shown the following:
- The incidents of breast cancer increase proportionately with the length of use of combined oral contraceptives prior to the birth of the first child.
- Users of combined oral contraceptives have a higher rate of breast cancer prior to age 35 as well as prior to age 45.
- Women who have used combined oral contraceptives within the previous 5 to 10 years have a higher risk of breast cancer.
Risk of breast cancer quadrupled before age of 18
urther supporting the World Health Organization’s classification, a 2006 study by the Mayo Clinic revealed that breast cancer risk increases 50% for women taking oral contraceptives four or more years before a full-term pregnancy. Additionally, a 2009 study by the Fred Hutchinson Cancer Research Center found women starting the pill before age 18 nearly quadruple their risk of breast cancer.
Likelihood of breast cell mutations
Why is this the case? As it turns out, the combination of estrogen and progesterone in the birth control pill functions as a genotoxin in the body. It encourages the multiplication of breast tissue, and can actually irreparably damage the DNA contained within that tissue. An increased number of cells in the breasts lead to a greater likelihood of mutations in cell division, which can ultimately result in cancer. Even more frightening, estrogen will cause any cells in the breast tissue that are already cancerous to develop and multiply more rapidly.

The right to be informed: anty-implantation mechanism of the pills and coils
Additioanlly many doctors are concerned about the fact that women often are not informed that the birth control pill can also cause an chemical abortion as well as prevent pregnancy. One medical journal declared, “If any mechanism of any OC [Oral Contraceptive] violates the morals of any particular woman, the failure of the physician or care provider to disclose this information would effectively eliminate the likelihood that the woman’s consent was truly informed and would seriously jeopardise her autonomy.
Hormonal pills and some other “birth control’ methods like intrauterine device (coils) very often act in anty-nidation way – while using them, a woman can still have “breakthrough ovulation”, which occurs in millions of women each year. A woman can still conceive a baby (embryo), who because of synthetic hormones cannot attach to the uterine lining and dies!
The pill’s third mechanism is to change the lining of the endometrium (the lining of the womb), which creates a hostile environment for a newly created human life. The tiny baby cannot implant and is spontaneously aborted by the body.
