A new study in the medical journal Cancer Research has found that Depo-Provera®, an injectable form of birth control, is linked to an increased risk of breast cancer. The birth control, which contains depo-medroxyprogesterone acetate (DMPA)–a form of the synthetic hormone progestin–can more than double a woman’s risk of developing invasive breast cancer if used for a year or more.
Invasive breast cancer spreads outside of the breast tissue into the lymph nodes, where it can then spread throughout the body. There are two main types of invasive breast cancer:
The link between DMPA use and the development of breast cancer also has been shown in several international studies that were conducted in Kenya, New Zealand, Thailand, Mexico, and Costa Rica.
Depo-Provera, which was approved by the U.S. Food and Drug Administration in October 1992, is injected by a patient into her thigh or buttocks four times a year. MSNBC reports that 1.2 million U.S. women are using Depo-Provera.
