The difference between ovarian cysts and ovarian tumors is manifested in the scope of the disease, clinical manifestations, treatment methods and other aspects. 1. In terms of disease scope, ovarian cyst belongs to a kind of benign ovarian tumor, while ovarian tumor includes benign and malignant tumors, so the scope is larger than cyst. 2. There is a difference between the two in terms of clinical manifestations. Ovarian cysts are mostly asymptomatic, and only larger cysts may present symptoms such as pain, fever, and abdominal masses. Benign ovarian tumors have no obvious symptoms, and malignant ovarian tumors also have clinical manifestations such as fatigue, fever, severe abdominal pain and weight loss. 3. In terms of treatment, ovarian cysts that meet surgical indications can be removed by surgery; malignant ovarian tumors need to be supplemented with chemotherapy, radiotherapy, immunotherapy, targeted therapy and other treatments in addition to surgery.
