Surgery is usually recommended for plasmacytoma, which is a benign tumor and a very common type of gynecologic tumor that is less likely to be fatal but needs to be treated with great attention. The reason is that even if this benign tumor is not treated surgically in time, it may become malignant after a long period of time. In severe cases, the ovaries may become malignant tumors, even secondary to bleeding and necrosis of the ovaries, and then the ovaries need to be removed even after surgery. The importance of the ovaries to women is self-evident, and they have a huge impact on endocrine secretion, so if a plasmacytic cystadenoma is found, it should be surgically removed at the first opportunity to avoid malignancy.
