The presence of High grade squamous intraepithelial lesion does not indicate that an individual has malignant uterine cancer in her body. Instead, it is just a level of classification for changes in the size and shape of cells in the cervix and is often found predating cervical malignancies. HGSIL is detected through a pap smear. Following its detection, a colposcopy will be utilized to confirm the results. Many treatments for the condition, such as LEEP procedures, cryotherapy, conization, and laster therapy can be utilized depending upon the situation and preferences of your treating physician.
