Ovarian nodules are cysts on the ovary, but they are not necessarily ovarian cancer. Ovarian masses are usually abnormal echoes on the ovary found during ultrasound examinations and are classified into physiological and pathological. If the ultrasound after menstruation shows that the cyst does not disappear or even grows, and the body is accompanied by abdominal pain and other discomfort, it is considered pathological and requires further examination, diagnosis and treatment. Tumors on the ovary also include junctional tumors and malignant tumors. If ultrasound examination reveals tumors on the ovary with papillae or moderate echogenic nodules, you need to go to the hospital as soon as possible for further examination and treatment.
