Hormonal birth control a carcinogenic to humans


Breast cancer and endometrial cancer are increased
Epidemiological studies consistently demonstrate an increased risk of breast cancer in women who used combined menopausal therapy. Largely confined to current or recent users, the risk increases with duration of use and exceeds that in women taking estrogen-only therapy. Endometrial cancer risks depend on the number of days that progestogens are included in the
combined therapy. When progestogens are taken fewer than 10 days per month, the risk of endometrial cancer is increased, but when progestogens are taken daily, the risk is similar to that in women who never used hormonal therapy. There was not sufficient evidence to conclude that hormonal therapy has a protective effect at any cancer site.
