If the vaginal discharge is watery and has no odor, this condition is clinically likely to be due to cancer of the fallopian tubes. A gynecological examination is recommended to find out if there are abnormal masses in the pelvis and an ultrasound is needed to find out if there are cystic or solid masses in the adnexal area. If this is present, tubal cancer is highly suspected. Such patients often have a history of chronic tubal inflammation. About 90% of tubal cancers are caused by previous chronic tubal inflammation, so analyze it together with clinical history. In addition, it is recommended to do three gynecological tumor tests, if the carcinoembryonic antigen and carcinoma antigen have been increased, the initial diagnosis can be made, and timely surgery is recommended.
