After menopause, the fibroid is still growing, which may be related to the supplementation of estrogen and progesterone or the high estrogen in diet and the malignant change of fibroid. 1. Diet: because fibroid is estrogen-dependent mass, so when there is a certain amount of estrogen in the body, it may lead to the increase of fibroid, and if postmenopausal women supplement estrogen or food with high estrogen content, it may stimulate the growth of fibroid. 2. Malignant change of fibroid: due to the degeneration of fibroid, when sarcomatoid change occurs, it is malignant change, due to the rich local blood flow, so the fibroid will grow gradually, and the general growth speed is relatively fast. For women with uterine fibroids, even if they have been menopausal, it is still necessary to regularly review gynecological ultrasound to check the size of the uterus, so as to facilitate early detection of lesions and early treatment.
