If a cyst on the ovary can disappear, it is a physiologic cyst, not a pathologic cyst, and if a pathologic cyst can disappear, it can only disappear through surgical removal. Clinically, it is important to distinguish whether the cysts on the ovaries are physiologic or pathologic. If it is a pathologic cyst, it is recommended to give timely surgical treatment. Physiologic cysts often occur in the second half of menstruation, and after menstruation is cleared, the cysts will shrink or disappear, and there is no need to intervene clinically in this case. For pathological cysts, surgery should be given as soon as possible and the cysts removed should be sent for pathological tests. Although most of the ovarian cysts are clinically benign tumors, malignant changes may also occur, and pathological diagnosis should prevail.
