It is recommended to change the hospital or another doctor to do another vaginal ultrasound examination, mainly to rule out whether the fibroids still exist. 2, due to the decline of hormone levels in the body, such as the occurrence of ovarian function decline, the estrogen in the body declines, the fibroids will shrink or even disappear. In addition, if the ovarian function has declined when entering the perimenopause, the estrogen level also decreases rapidly, the fibroids will shrink or even disappear, which is normal because fibroids are estrogen-dependent tumors.
