Bumps on the outside of the uterus may occur in the body of the uterus or in the cervix. If the bumps occur in the body of the uterus, they are usually considered to be subplasmic fibroids, which are a relatively common benign gynecological neoplastic disease, the cause of which is related to high estrogen levels and imbalance of estrogen and progesterone levels, as well as to uncoordinated sexual life and long-term emotional disorders. If the myoma is relatively small, there are usually no obvious clinical symptoms and no obvious adverse effects on normal menstruation, it can be temporarily left untreated. If the bumps appear in the cervix, they are mostly considered to be cervical polyps, which are benign lesions that occur in the cervix and are mostly related to chronic inflammatory stimulation. Cervical polyps can easily cause contact bleeding, secondary infection is prone to abnormal leucorrhea, it is best to promptly undergo surgery, laser, freezing and other treatments.
