How much fibroid grows in a year is not fixed, some patients grow slowly and some patients grow fast. Uterine fibroids are most common in women in their reproductive years. Stimulated by cyclic fluctuations in the level of estrogen and progesterone, fibroids in a woman’s body will usually grow but slowly, and after menopause when the hormone level in the body decreases, fibroids may shrink or disappear. After menopause, the hormone level drops, and the fibroids may shrink or disappear. Some patients have uterine fibroids combined with pregnancy, and under the stimulation of too high a level of estrogen and progesterone in the body, the growth rate of fibroids will be faster; some patients’ fibroids may undergo malignant changes, which can also lead to the excessive growth of fibroids, and require timely surgical treatments. Therefore, patients with uterine fibroids should have regular medical checkups and seek timely medical treatment when abnormalities are found, so as to avoid delaying the condition and leading to adverse consequences.
