Women taking birth control pills will not cause uterine fibroids. Birth control pills are a combination of estrogen and progestin, which will act as a contraceptive after oral administration. The cause of uterine fibroids is not clear so far, but after clinical observation, it is found that women in their reproductive age will grow under the effect of estrogen because the secretion of estrogen and progesterone in their bodies is relatively strong. When women enter menopause, the ovarian function declines and the level of estrogen decreases, so fibroids tend to shrink or disappear after menopause, so it proves that there is a relationship with estrogen. If a patient with fibroids takes birth control pills, it may cause fibroids to grow faster, but if there are no fibroids originally, it is not possible to grow fibroids by taking birth control pills, so this should be differentiated.
