If a mass is found in the ovary and the results of the five tumor marker tests are normal, further relevant examinations (such as ultrasound, CT, MRI, etc.) are needed to choose the treatment plan according to the diagnostic results. Ovarian masses can be divided into benign and malignant, benign common ovarian tumor-like lesions, tubo-ovarian cysts, uterine fibroids, etc., and malignant common ovarian cancer, specific treatments are as follows. 1. Ovarian tumor-like lesion, usually under observation, can disappear by itself in 2~3 months, if the lump persists or increases in size, malignant transformation may be more likely. 2. Tubo-ovarian cysts, if the cysts are small and asymptomatic, ultrasound can be reviewed regularly, if the cysts are large, surgical resection can be chosen, and commonly used surgical methods include laparoscopic cystectomy. 3. Uterine fibroid: subplasma fibroid can be easily confused with ovarian mass, and the fibroid is often multiple, ultrasonography can help to identify it. Asymptomatic uterine fibroids usually do not need treatment and can be rechecked once every 3~6 months. If the fibroids cause anemia, compression symptoms or malignancy, surgical resection should be considered, and hysteroscopic myomectomy is commonly used. 4. Ovarian cancer: Early signs are not obvious, and the diagnosis can be made by imaging examination, such as ultrasonography, which has a diagnostic compliance rate of over 90%, magnetic resonance, CT and so on, which can also help to determine the scope of lesions. Once discovered, surgical treatment should be performed to remove the tumor and decide whether chemotherapy is needed in the later stage according to the pathological results. If an ovarian mass is found, relevant examinations should be completed as soon as possible to clarify the nature of the mass and provide early treatment to avoid progression of the disease.
