Squamous cell carcinoma is the most common type of cancer in the oral cavity. It starts from squamous cells — the thin, flat cells that form the inner lining of the mouth. The oral cavity includes the lips, the front two-thirds of the tongue, the inner cheeks (buccal mucosa), the floor of the mouth, the …

Atypical endometrial hyperplasia (AEH) is a precancerous condition of the lining of the uterus, called the endometrium. In AEH, the endometrium becomes abnormally thick and the glandular cells that make up the endometrium start to grow in a crowded and irregular pattern. The cells also look abnormal under the microscope, which is why the word …

Endometrial hyperplasia without atypia is a noncancerous condition in which the lining of the uterus (called the endometrium) becomes thicker than normal. This happens because the endometrial glands grow and multiply more than they should. Although this condition is not cancer, it can sometimes develop into cancer over time, especially if it is left untreated …

A hyperplastic polyp is a common benign (non-cancerous) growth that develops on the inner surface of the colon or rectum. Hyperplastic polyps are not precancerous. They do not contain the abnormal cells that lead to cancer, and in most cases, finding one does not change your cancer screening schedule at all. If this finding is …

Usual ductal hyperplasia (UDH) is a non-cancerous (benign) condition commonly found in breast biopsies. It describes an increase in the number of normal-looking cells within the small ducts of the breast, typically in a region of the breast known as the terminal duct lobular unit. These cells multiply in a disorganized manner but do not …

HPV-associated squamous cell carcinoma is the most common type of cervical cancer. It develops from squamous cells — the flat cells that line the outer surface of the cervix — following persistent infection with high-risk human papillomavirus (HPV). Most cases develop slowly over many years from a precancerous condition called high-grade squamous intraepithelial lesion (HSIL). …

High grade squamous intraepithelial lesion (HSIL) is a precancerous disease caused by human papillomavirus (HPV). It is composed of abnormal squamous cells that have been infected and transformed by the virus. Squamous cells are found in a thin layer of tissue called the epithelium which covers the surface of the vulva. There are many types …

Low grade squamous intraepithelial lesion (LSIL) in the vagina is an abnormal growth caused by infection with human papillomavirus (HPV). The abnormal growth seen in LSIL is an example of dysplasia. In addition to the vagina, LSIL can also affect the anal canal, vulva, and cervix. In men, LSIL can affect the penis and scrotum. …

Low grade squamous intraepithelial lesion (LSIL) is a precancerous condition of the cervix caused by infection with human papillomavirus (HPV). It is made up of squamous cells that have been infected and changed by the virus. These abnormal cells are usually found in the transformation zone, which is the part of the cervix where glandular …
