Uterine fibroids are the most common benign tumors of the female genitalia. How fibroids are caused is not yet clear and may be related to estrogen and progesterone levels and chromosomal abnormalities in the body. 1, related to estrogen and progesterone: uterine fibroids are common in women of childbearing age, rare in adolescence, and often shrink or subside after menopause, which indicates that the occurrence of uterine fibroids is likely to be related to female sex hormones. In addition, fibroids grow significantly under the stimulation of pregnancy or other high sex hormones, such as consumption of health products containing hormones or long-term heavy use of birth control pills. The fibroid tissue is highly sensitive to estrogen and can promote fibroid growth when the patient has high estrogen levels. In addition, progesterone has also been confirmed to have the role of promoting the growth of fibroids. 2, related to family inheritance: some patients with uterine fibroids have a family history of fibroids, suggesting that the presence of some fibroids may be related to chromosomal abnormalities, which can lead to the proliferation of cells in the uterine wall and thus the formation of fibroids. 3, life risk factors: (1) age, uterine fibroids are common in women of childbearing age 30-50 years old, age is one of the most important risk factors for uterine fibroids, women with reproductive capacity, the older they are, the higher the risk of developing uterine fibroids; (2) mental stress, mental stress can affect women’s estrogen and progesterone levels to a certain extent, high estrogen and progesterone levels are the main risk factors for the occurrence of uterine fibroids. High estrogen and progesterone levels are the main risk factors for the development of uterine fibroids. High estrogen and progesterone levels are the main risk factors for the development of uterine fibroids. Women with higher education levels are at higher risk of developing fibroids due to their higher mental stress. The development of fibroids is likely to be the result of a combination of factors.
