Cervical cancer is one of the most common malignant tumors in the female reproductive system and the leading cancer type in female mortality worldwide. However, detection and treatment of cervical cancer at an early stage can greatly improve cure rates, so screening and early diagnosis are very important. Medical ultrasound scanner plays an increasingly important role in cervical cancer screening. This paper will introduce its application.

The medical ultrasound scanner is a safe, painless and efficient examination method that produces high-resolution images to assess the state of the body's internal organs and tissues. In cervical cancer screening, ultrasound scanners can help doctors assess the shape, size and structure of the cervix and determine if there are any abnormalities.

The following is the application of medical ultrasound scanner in cervical cancer screening:

Cervical structural examination: By using an ultrasound scanner, the doctor can examine the size, shape, and structure of the cervix. A normal cervix should be a cone shape with an even thickness and a smooth surface. If there are abnormalities, such as thickening or an irregular shape, this may indicate the presence of an underlying cervical cancer.

Endocervical examination: Ultrasound scanners can also be used to examine the lining of the cervix. The endometrium of the cervix is the inner layer of the cervix composed of endothelial cells, which is also one of the origins of cervical cancer. An ultrasound scanner can detect the shape and position of the inner membrane and determine if there are any abnormalities.

Cervical lymph node examination: The status of lymph nodes is very important in the diagnosis of cervical cancer. If cervical cancer has spread to the lymph nodes, it becomes much more difficult to treat. An ultrasound scanner can detect swollen or abnormal lymph nodes around the cervix, allowing early detection of possible metastases.

Biopsy guided: If the ultrasound scanner detects cervical abnormalities, the doctor may need to perform further tests to determine the nature of the lesion. In this case, ultrasound scanners can be used to guide tissue biopsies. The doctor can use the scanner to determine the best path to the lesion and direct tissue sampling if needed.

In conclusion, medical ultrasound scanner is widely used in cervical cancer screening. By assessing the structure, intima and lymph node status of the cervix, as well as conducting tissue biopsies, doctors can detect potential cervical cancer lesions early and plan treatment accordingly. Ultrasonic scanner is a safe, noninvasive examination method that does not cause any damage to the body, so it is widely used in clinical practice. With the continuous progress of the technology, it is believed that medical ultrasound scanners will be more widely used in cervical cancer screening in the future, providing more women with better health care services
