Can color ultrasound detect cervical cancer?

Color Doppler Ultrasound can assist in screening for cervical cancer, but the diagnosis must be combined with cervical cytology or biopsy. Cervical cancer screening mainly relies on HPV testing and TCT examination, and color ultrasound is more used to evaluate tumor size and metastasis.

Transvaginal color ultrasound can observe cervical morphology and blood flow signal abnormalities. The detection rate of early cervical cancer is limited, but mid-to-late stage lesions can show cervical enlargement, structural disorder and other characteristics. Abdominal color ultrasound has low resolution and can only detect larger lesions or lymph node metastasis. The advantage of color ultrasound is that it is non-invasive and repeatable, and is suitable for postoperative follow-up monitoring of recurrence. Some patients with cervical cancer may have ultrasound manifestations such as widening of the cervical canal and uneven echoes, but inflammation or benign lesions may also have similar images, and comprehensive judgment needs to be combined with tumor markers and other factors.

For high-risk groups with contact bleeding and abnormal vaginal discharge, colposcopy is still recommended even if no abnormalities are found on color ultrasound. Cervical atrophy in postmenopausal women may make color ultrasound imaging difficult, and special probes need to be used to increase the detection rate. Magnetic resonance imaging is preferred for cervical cancer screening during pregnancy to avoid misdiagnosis of physiological cervical changes by color ultrasound.

It is recommended that women over 30 years old undergo TCT combined with HPV screening every 3 years, and high-risk groups can shorten the interval. When symptoms such as irregular vaginal bleeding and sexual intercourse pain occur, you should seek medical treatment promptly to avoid relying solely on color ultrasound results to delay diagnosis. Daily attention to preventive measures such as HPV vaccination and avoiding multiple sexual partners can reduce the probability of cervical cancer.
