Women pay attention to these statistics. A Mayo Clinic study demonstrates that any female who is on hormonal birth control for four years or more prior to her first full-term pregnancy has an increased risk of breast cancer of 52%. Since 1975, there has been a 400% increase in breast cancer among pre-menopausal women over these same years which mirrors the increased use of hormonal birth control. Women who use hormonal birth control for more than five years are four times as likely to develop cervical cancer. The World Health Organization now classifies all hormonal contraceptives as Group 1 carcinogens. The safest contraceptive methods are barrier methods. |
