There is no single standard for how large a fibroid requires surgery, it is influenced by many factors and the standard varies in different cases. If the submucosal fibroids or cervical fibroids are prolapsed, resulting in irregular vaginal bleeding, this kind of fibroids need to be surgically removed regardless of their size. If the fibroid is within the myometrium, generally <5 cm, surgery is not required. If the fibroid is subplasma, surgery is not required if the fibroid is <5 cm, or >5 cm, as long as the fibroid does not grow particularly fast and does not twist, observation can be continued. If the fibroids in the myometrium are <5cm but grow close to the patient's endometrium, resulting in irregular vaginal bleeding, surgery may be an option. The cost of uterine fibroid surgery is mainly related to the surgical method chosen by the patient. If you choose laparoscopic minimally invasive surgery, the cost is about 15,000-20,000 yuan, and if you do open surgery or transvaginal surgery, this cost is about 10,000-15,000 yuan.
