In a Pap test the abnormal cells are often grouped together although your pathologist may also see single abnormal cells on the slide. Almost all cases of HSIL are positive or reactive for p16 which means your pathologist saw the p16 protein in the abnormal cells. … The outer surface of the cervix is lined by two types of cells that form a barrier called the epithelium. Larger samples of tissue are usually sent for pathological examination as a single piece of tissue and the tissue is then divided into multiple sections before being examined under the microscope. It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body. This page is intended to provide information about anal cancer and its precursors, high grade and low grade anal squamous intraepithelial lesions(HSIL and LSIL respectively).

We also have a national list of providers who have been trained in HRA (high resolution anoscopy), the technique currently thought to be the best for detecting precancerous lesions and anal cancer. Whether the lesion is high grade or low grade is determined by taking a tiny biopsy of the lesion. It's important to remember that very few areas of HSIL ever turn into anal cancer. In a tissue biopsy, the abnormal cells are usually found throughout the epithelium. The cervix is part of the female genital tract.
