Highly squamous intraepithelial lesions are associated with leukorrhea. High-grade squamous intraepithelial lesions are changes in the epithelial cells of the cervix. Abnormalities in the epithelial cells of the cervix are associated with increased leukorrhea or blood in the leukorrhea. Highly squamous intraepithelial lesions can cause leukorrhea, but it does not necessarily mean that the presence of leukorrhea or increased leukorrhea is a sign of highly squamous intraepithelial lesions. For example, having vaginal inflammation, chronic cervicitis, and ovulation are also likely to cause increased leukorrhea. If you suspect high squamous epitheliopathy on the cervix, you need to perform cervical liquid-based cytology and a colposcopic cervical multisite biopsy to determine the condition. If uncomfortable symptoms occur, it is necessary to consult the doctor in time for relevant examinations to determine the cause of the disease and then carry out treatment to avoid delaying the disease.
