Birth control pills increase the risk of ovarian cancer
A dangerous and completely untrue assertion about birth control pills is that they increase the risk of ovarian cancer. As a matter of fact, regularly taking birth control pills has actually been shown to DECREASE the risk of ovarian cancer. Scientists have been unable to confirm why this is, but they hypothesize that ovulation could increase the chance of ovarian cancer (birth control pills reduce the frequency of ovulation). The protection that birth control pills provide depends on how long women continuously take them, and protection is diminished after a year of being off the pill. Note however that birth control pills come with their own set of risks, and have been known to increase the risk of blood clots, strokes, high blood pressure and even cervical and breast cancer. These risks are increased especially in women over 35 who smoke regularly.
