There is only one way for patients to self-examine cervical cancer, which is based on clinical symptoms. The most typical clinical symptom of cervical cancer is contact bleeding. Contact bleeding refers to vaginal bleeding after intercourse or after gynecological examination. The amount of vaginal bleeding is related to the size of the lesion and the size of the invading blood vessels. In addition, some patients also have increased menstrual flow, prolonged menstrual periods or spotting, but clinical symptoms are only a preliminary screening. When patients have these symptoms, they must go to the hospital for cervical cancer screening, starting with TCT and HPV, which are required for cervical cancer screening, and further colposcopy if there are problems with the test. If colposcopy is problematic, a cervical biopsy will be performed under colposcopic monitoring and sent for pathology for final confirmation of the diagnosis.
