Uterine fibroids are the most common type of benign tumor of the female genitalia. It is mostly asymptomatic, with a few manifestations such as vaginal bleeding, palpable abdominal masses and pressure symptoms. It can be painful in case of torsion or other conditions. Uterine fibroids mostly occur in middle-aged women. 41-50 years old account for about 50%; 31-40 years old account for about 28%; 21-30 years old and 50-60 years old rarely occur; 60 years old and above rarely occur. The youngest age of the disease is reported in the literature as 10-15 years. In conclusion, 70%-80% of uterine fibroids occur at the age of 30-50 years, i.e., during the period of vigorous ovarian function, and decrease sharply after the age of 50 years with the decline of ovarian function.
