Why does taking the contraceptive pill reduce the risk of ovarian cancer?

Every time a woman ovulates, her ovaries sustain a bit of damage due to the egg rupturing out of the ovary. OCPs decrease the number of lifetime ovulations which decreases the risk of ovarian cancer, since you decrease the number of lifetime damage.

Cancer can be thought of as a problem with how cells grow where the mechanism that tells cells to stop multiplying gets damaged. These cells that keep multiplying when they are not supposed can become cancer. Before a womans period, cells in the breasts and uterus multiply as the body prepares to have a baby. The more times the body goes through this process, the more likely some cells get damaged and dont get the signals to stop multiplying. Long term birth controls reduce the length or how often these growth cycles happen, so reduce the chances of cell multiplying errors from happening.

Some female related cancers are hormone related. As in estrogen. OCP’s contain levels of progesterone( pregnancy hormone) to make the body believe it is pregnant. Increased progesterone levels decrease the level of estrogen affecting the body, thereby decreasing the optimal conditions for estrogen related tumors from growing. Being pregnant is a natural estrogen break as well.
