Ultrasound can be used to detect cervical cancer, which has a high incidence and usually progresses to an intermediate to advanced stage if it can be recognized on ultrasound. When cervical cancer in the middle or late stage leads to lesions in the cervical tissues, such as the appearance of masses and invasion of paratesticular tissues, it can be shown on ultrasound, suggesting that there are cervical lesions. In such cases, the doctor will recommend the patient to undergo other tests to confirm the diagnosis. Currently, the best way to screen for cervical cancer is cervical tissue cytology. Cervical cytology is recommended once a year for women over the age of 35 for early detection of cervical cancer and timely treatment. Experienced ultrasonographers can detect cervical enlargement, stiffness, masses inside the cervix, and abnormal blood flow signals through transvaginal ultrasonography, in which case the doctor highly suspects the presence of cervical cancer.
