Cervical precancerous lesions are the initial cervical epithelial changes in the development of cervical cancer caused by HPV infection. Most cervical precancerous lesions and early cervical cancer have no specific symptoms and can be detected during physical examination. Some women may have increased vaginal discharge with odor due to combined vaginitis, and some may have contact bleeding after sex or gynecological examination due to combined cervicitis. Therefore, annual gynecological examination is the secret weapon to detect cervical precancer and early cervical cancer, and it is important to insist on the examination regardless of whether you are unwell or not. Cervical cancer screening during gynecological examination includes TCT and HPV test. TCT can detect early cellular changes and HPV can detect high-risk viral infection. If abnormalities are found, the doctor will perform colposcopy and remove a small piece of tissue from the cervix to send for pathological examination to clarify the presence of precancerous lesions; once precancerous lesions are found, the doctor will take measures to stop the disease from progressing, most of which require surgical removal. Surgical treatment is very effective and does not affect life and work. It can be seen that regular gynecological examination can detect cervical precancerous lesions and early cervical cancer. And through standardized diagnosis and treatment, satisfactory results can be achieved.
