Ovarian cancer can be detected by ultrasound, but at present, ultrasound can only be used as an early screening and cannot confirm the diagnosis. Therefore, patients need further examination to confirm the diagnosis after checking out, and also need laboratory test to check whether the tumor markers in the body are positive or not, common alpha-fetoprotein, CEA, CA199. If the result is positive, puncture cell biopsy can be done in the lesion area of the ovary to check whether there are cancer cells, and the diagnosis can be confirmed at the initial stage. Patients can also take lesion tissues locally through laparoscopy to do pathological test directly, which can confirm the diagnosis and at the same time understand the nature, type and infiltration degree of the cancerous lesion. The malignant degree of ovarian cancer is generally very high, and the 5-year survival rate is relatively low. Timely diagnosis of early ovarian cancer is very helpful for early treatment of the disease. In addition, ovarian malignant tumors are mainly treated by surgery and supplemented by comprehensive treatment such as radiotherapy chemotherapy and traditional Chinese medicine.
