Plasmacytoma is a benign tumor that is not serious. However, once this tumor is diagnosed, surgery must be done as soon as possible. This is because this kind of tumor may develop malignant changes over time, and it is also possible to develop ovarian tumor tip torsion. If there is a torsion of the ovarian tumor, it must be treated with surgery as soon as possible. If the torsion is prolonged, necrosis of the ovary may occur, so if the surgery is done late, the ovary cannot be preserved, and it will have an impact on the endocrine system of women. If the plasma cystadenoma develops malignant changes, it is ovarian cancer, which has a very great impact on women’s health. Therefore, as long as the tumor is determined to be plasmacytoma, it must be treated as early as possible to avoid adverse consequences.
