The risk of fibroids is usually low if they are asymptomatic. The risk is high if the fibroids increase significantly in size and are associated with menstrual abnormalities, abnormal vaginal discharge, or if the fibroids become malignant. Some patients with fibroids will not show clinical manifestations and can be found during physical examination, and the risk of such fibroids is usually small. The risk is higher if the uterine fibroids increase rapidly and there are menstrual abnormalities such as increased menstrual flow, prolonged menstrual period, irregular bleeding during non-menstrual period, short intervals between menstruation, as well as leukorrhea, purulent leukorrhea, foul-smelling vaginal discharge, lower abdominal distension, and lower back pain, and so on. In addition, uterine fibroids also have a certain chance of malignant transformation, if the patient’s uterine fibroids have malignant transformation, the risk is relatively high. Fibroid patients need to seek timely medical treatment, and the doctor will determine the risk according to the size and nature of fibroids. It is recommended that when fibroid tumors increase in size or become malignant, the patient should follow the doctor’s instructions and take appropriate measures to treat the tumor.
