The majority of uterine smooth muscle tumors are benign when immunohistochemistry is done, and very few have malignant proliferation. Uterine smooth muscle tumors are generally benign and are benign tumors formed by the proliferation of uterine smooth muscle tissue. The exact cause of the disease is unknown, but the prevailing theory is that it may be related to genetics, hormone levels, and stem cells. The disease is most common in women between the ages of 30 and 50, with occasional, but rare, cases in women under the age of 20. Since the tumor is benign and proliferates very slowly, it may even be left untreated if the fibroid is small and the patient is asymptomatic, and if the patient undergoes surgery, immunohistochemistry and tissue biopsy are options, but in general most of the tumors are benign. When uterine smooth fibroids appear, you need to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
