Cervical fibroids belong to a special type of uterine fibroids, and the main causes are related to genetic factors, sex hormone levels, and triggering factors. 1. Genetic factors: research shows that the occurrence of this disease is related to heredity, for example, if there are patients with cervical fibroids, their daughters have a higher risk of developing the disease than normal people. 2. Sex hormone levels: For women of childbearing age with high sex hormone secretion, the risk of cervical fibroids is higher. Recent use of sex hormone drugs may also increase the size of cervical leiomyoma, so the occurrence of cervical leiomyoma is considered to be related to sex hormone levels. 3. Predisposing factors: People with a family history of cervical fibroids, patients receiving hormone supplementation therapy, and those with polycystic ovary syndrome have a much higher risk of developing cervical fibroids than the general population. There may be other reasons for the occurrence of cervical fibroids, so it is necessary to cooperate with the doctor to carry out examinations, and then make targeted treatment and therapy.
