The colposcopic finding of vaginal vinegar-white skin is not necessarily vaginal cancer; it is the thickness of the vinegar-white epithelium and the pathologic diagnosis that determines whether it is vaginal cancer. The acetic acid test is a method used during colposcopy to check for suspicious lesions. Normal vaginal squamous epithelium retains its original pink color under the acetic acid test, while cells with an increased nuclear-to-plasmic ratio in abnormal tissues will show a temporary white lesion. The presence of a lesion in the vaginal epithelium is suspected in the case of thicker acetic acid epithelium with very clear borders. The presence of a thin white acetic acid epithelium on the surface of the vagina coated with acetic acid often suggests that it may be due to localized inflammation. However, whether the lesion is cancerous or not should be determined by taking local tissues and sending them for pathologic examination, and the results of the pathology will determine whether it is cancerous or not. If there is white acetic acid epithelium, don’t worry too much, you can determine whether you have vaginal cancer through pathological examination, and then treated under the guidance of professional physicians.
