If a pelvic mass is found during physical examination, it is necessary to roughly judge the source of the pelvic mass, ovary or fallopian tube according to the ultrasonic examination. If it is ovary, it can be divided into physiological cyst and pathological cyst. If it is the first time, you can observe it conservatively for three months to see if the mass has changed in these three months. If necessary, it may be treated by surgery, because only by taking pathological tissue through surgery for pathological examination, can we know exactly what causes pelvic mass, but before surgery, there should also be a tendency, whether it is benign or malignant.
