In LGSIL, or low-grade intraepithelial lesions, the patient presents with mild dysplasia and some changes in the cells that point to infection by the human papilloma virus, says Healthcommunities.com. High-grade squamous intraepithelial lesions, or HGSIL, is indicated by dysplasia that is moderate to severe. There may also be precancerous lesions and even evidence of cervical cancer in situ. This means the malignancy is only found in the topmost cells of the cervix and hasn't penetrated into deeper layers.

The CIN, or cervical intraepithelial neoplasia grading system, uses numbers, claims Healthcommunities.com. Atypia is the same as the Bethesda system's ASCUS. CIN I correlates with LGSIL, while CIN II and III are nearly the same as HGSIL. The staging then progresses to carcinoma in situ and then cervical cancer.

It is important for women to be checked for cervical dysplasia, because cervical dysplasia by itself is asymptomatic, says Healthcommunities.com. Any symptoms come from other conditions or diseases. The best way to check for cervical dysplasia is for the patient to have a Pap smear. In this procedure, the doctor collects cells from the cervix and a medical professional examines them to see whether or not they are abnormal.
