The proposed diagnosis of HSIL by colposcopy indicates the presence of a high degree of intraepithelial neoplasia of the cervix and is less likely to be misdiagnosed. Colposcopy is usually performed after human papillomavirus, or HPV, and cervical liquid-based cytology, or TCT, tests. Abnormal results of HPV and TCT indicate that the patient has the possibility of cervical pathology, and therefore needs to be clarified by colposcopy. During colposcopy, vinegar-white and iodine tests are performed, and localized tissues are taken for pathological examination, which is more accurate and less likely to miss the diagnosis. If a woman finds HSIL results after colposcopy, it suggests that there is a high degree of intraepithelial neoplasia in the cervix, which may develop into invasive carcinoma, she needs to consult a doctor in time, complete the relevant examinations, clarify the cause of the disease under the guidance of a professional doctor, and take targeted treatment, such as cervical conization, so as to avoid delaying the condition.
