Cervical cancer cannot be detected by doing ultrasound. Ultrasound refers to gynecological transvaginal ultrasound, which is mainly used for checking vaginitis, pelvic inflammatory disease and cervicitis, and cannot check whether there is cancer in the cervix. Cervical cancer, also known as uterine cervix cancer, is mainly caused by human papilloma virus infection, and may have symptoms such as contact bleeding, increased vaginal discharge, etc. It is necessary to go to the hospital for examination in time, and can be diagnosed through cervical cytology examination and HPV examination. If cervical cancer is diagnosed, further systemic examination is needed to determine the stage of cervical cancer, and according to age and reproductive needs, appropriate treatment should be chosen under doctor’s guidance to control the progression of the disease and avoid metastasis of cancer cells, which will jeopardize health.
