Can color Doppler ultrasound detect cervical cancer?

The cause of cervical cancer is still unclear. Clinically, the incidence rate is higher in women who marry early and have children early. There are no symptoms in the early stage of cervical cancer, but in the later stage, patients will have abnormal vaginal bleeding. The treatment rate of mid- and late-stage cervical cancer is very low. As a woman, in addition to keeping yourself clean, you must also be vigilant and seek medical attention in time if you find any symptoms.

1. Biopsy of the cervix and endocervical canal

It is one of the most reliable and essential tests for diagnosing cervical cancer and precancerous lesions. Samples are collected at multiple points such as 3, 6, 9, and 12 o'clock at the junction of the squamous-columnar epithelium of the subject's cervix. In order to improve the accuracy of sampling, biopsy can be performed under the guidance of iodine test or colposcopy.

Iodine test: Apply iodine solution on the cervix and vagina. The normal cervical and vaginal squamous epithelium will be stained brown or dark reddish brown. The unstained area is the danger area and biopsy should be taken from this area.

Colposcopy: It can observe whether there are abnormal cells and changes in the direction of blood vessels on the surface of the cervix, and take biopsies from suspicious areas. If the cytology examination is suspicious but the cervical biopsy is negative, a small scraper should be used to scrape the endocervical canal for biopsy.

2. Imaging and endoscopy

B-ultrasound, CT, MRI, lymphangiography, colonoscopy, cystoscopy, intravenous pyelography, etc. can understand the extent of lesion invasion and assist in clinical staging.

3. Cervical smear cytology examination

It is the most effective method for detecting early cervical cancer. It is currently widely used in cancer prevention screening, with a positive rate of more than 90%. The sample is taken from the junction of the squamous-columnar epithelium of the cervix of the subject and then smeared on a glass slide. After fixation and staining, it is examined under a microscope. If suspicious cancer cells or nuclear heterogeneous cells are found, a cervical biopsy should be performed.

4. Cervical conization examination

When multiple cervical cytology tests are positive but cervical biopsy results are negative, or when the biopsy is carcinoma in situ and invasive cancer cannot be ruled out clinically, cervical conization can be considered for the patient. The specimens removed are examined by serial pathological sections.

Warm reminder: The treatment rate of early cervical cancer has been improved. How long patients can live with early cervical cancer is largely attributed to early detection, early diagnosis and early treatment of cervical cancer. Since the carcinoma in situ of early cervical cancer is confined to the skin or mucous membrane, without metastasis or deep infiltration, the 5-year survival rate can reach more than 90% after effective treatment. The treatment rate of early cervical cancer found under a microscope has reached 100%. If the lesion is discovered and treated in the early stage, the success rate of complete recovery is quite high.
