Introduction
The main screening methods for cervical precancerous lesions include cervical cytology (Pap smear), human papillomavirus (HPV) testing, colposcopy, cervical tissue biopsy, and biomarker testing. These examinations help assess the condition of cervical lesions, further analyze whether cervical cells show a tendency toward malignancy, and aid in further diagnosis. However, the above methods should be performed under a doctor's guidance to ensure accuracy.
Generally, the main screening methods for cervical precancerous lesions include cervical cytology, human papillomavirus (HPV) testing, colposcopy, cervical tissue biopsy, and biomarker testing. If any adverse reactions occur, prompt medical consultation is recommended. Detailed explanations are as follows:
1. Cervical Cytology
Cervical cytology primarily involves collecting a sample from the cervical surface using a brush. The specimen is then sent to a laboratory for analysis. The presence of cervical precancerous lesions is determined based on the morphology and structure of the cells.
2. Human Papillomavirus (HPV) Testing
HPV infection is a primary cause of cervical precancerous lesions. Therefore, timely testing for the presence of HPV in the body is necessary. This testing is typically performed by collecting cervical epithelial cell samples or urine samples.
3. Colposcopy
Colposcopy involves using a magnifying lens to examine the vagina for abnormal changes. If vaginal mucosal abnormalities are detected, samples should be promptly collected for further analysis of cervical changes, allowing for a preliminary diagnosis of possible cervical precancerous lesions.
4. Cervical Tissue Biopsy
Cervical tissue biopsy is a commonly used method for diagnosing cervical precancerous lesions. It involves removing a small piece of tissue from the cervical lesion area and sending it to a laboratory for pathological analysis to promptly rule out malignant changes.
5. Biomarker Testing
Biomarker testing can be used to diagnose early-stage cervical precancerous lesions, as the cervix may release specific biomarkers during the precancerous stage. These biomarkers can be further analyzed through blood testing.
The above diagnostic methods should be selected based on individual conditions and the severity of the lesion. It is also recommended to undergo these tests under the guidance of a qualified physician to ensure accuracy.
