How large must uterine fibroids be before surgery is considered necessary?

Surgery is generally recommended when uterine fibroids exceed 5 centimeters in diameter or cause severe symptoms. Whether surgery is required for uterine fibroids mainly depends on the size of the fibroids, their rate of growth, and whether they are accompanied by symptoms. Common symptoms include excessive menstrual bleeding, abdominal pain, frequent urination, or a feeling of pressure.

In most cases, asymptomatic uterine fibroids with a diameter of less than 5 centimeters do not require surgical intervention and can be monitored for any changes through regular follow-up examinations. If fibroids cause excessive bleeding during menstruation, leading to anemia, or result in pelvic compression symptoms such as difficulty urinating or constipation, surgical treatment may be necessary even if the fibroids are less than 5 centimeters in size. If a fibroid grows rapidly in a short period of time or increases in size after menopause, it may indicate a risk of malignancy, and doctors will generally recommend its removal as a priority. If the location of the fibroids may affect pregnancy before attempts to conceive, such as submucosal fibroids or large intramural fibroids, surgical removal should also be considered to reduce the risk of miscarriage.

In rare cases, even if individual fibroids are small in size, their collective effect can cause the uterus to exceed the size of a uterus at 12 weeks of pregnancy, potentially requiring surgical intervention to address the structural issues. For fibroids located in special areas, such as those in the cervix or broad ligament, the indications for surgery are appropriately expanded due to the anatomical complexity or the potential compression of the ureters and other factors. Furthermore, in cases where sarcomatous changes are suspected or the possibility of a malignant tumor cannot be ruled out, surgical exploration should be performed as soon as possible, regardless of the size of the lesion. For some patients, repeated blood transfusions are necessary due to severe anemia, or surgical intervention becomes an essential option to improve their quality of life when pain symptoms cannot be controlled with medication.

Patients with uterine fibroids should avoid foods high in estrogen in their daily diet, such as royal jelly and animal ovaries. However, they can moderately consume high-quality protein and iron supplements to prevent anemia. Have gynecological ultrasound examinations every 3 to 6 months; seek medical attention immediately if there is abnormal vaginal bleeding or acute lower abdominal pain. The type of surgery required must be determined by a doctor based on a comprehensive assessment of the patient’s age, fertility needs, and the characteristics of the fibroids. Common procedures include myomectomy, uterine artery embolization, or total hysterectomy.
