Normal vaginal ultrasound and risk of cervical cancer

When vaginal ultrasound results are normal, the probability of cervical cancer is low, but vaginal ultrasound cannot completely rule out the risk of cervical cancer. Cervical cancer screening needs to be combined with HPV testing and cervical cytology. Factors such as persistent high-risk HPV infection, multiple sexual partners, low immune system function, long-term oral contraceptives, and smoking affect the risk of the disease.

Vaginal ultrasound mainly uses ultrasound to observe the structure of the uterus and cervix, and has limited sensitivity for early-stage cervical cancer or precancerous lesions. Cervical cancer in the early stage may only manifest as cervical intraepithelial neoplasia, and the characteristics of vaginal ultrasound imaging are not obvious. In clinical practice, vaginal ultrasound occasionally shows normal cervical morphology, but cases of cervical cancer diagnosed by biopsy are mostly related to the hidden location of tumor growth or the small size of the lesion.

The standardized cervical cancer screening strategy recommends that women over the age of 21 undergo cervical cytology examination every three years, and women over the age of 30 can undergo combined HPV testing. If HPV16/18 positivity persists or cytology is abnormal, colposcopy biopsy is required for diagnosis. HPV vaccination can prevent more than 70% of cervical cancer, and the optimal age for vaccination is 9-26 years old. Risks can be further reduced by measures such as maintaining a single sexual partner, quitting smoking, and strengthening immunity.

When symptoms such as contact bleeding and abnormal vaginal discharge occur, you should seek medical treatment in time even if the vaginal ultrasound is normal. It is recommended to participate in two cancer screenings regularly to avoid neglecting follow-up follow-up due to a normal vaginal ultrasound result. Cooperating with the doctor to inspect and palpate the cervix during gynecological examination can improve the detection rate of early lesions.
