Anal intraepithelial neoplasia (AIN) is a precancerous condition that affects the cells lining the anus and anal canal. In this condition, the surface cells show abnormal changes, but they have not spread into deeper tissues, which means it is not cancer. However, some cases can progress over time to squamous cell carcinoma of the anus. …

In a pathology report, the term non-invasive means that a tumour or abnormal growth has not spread into the surrounding tissues. The abnormal cells are confined to the original layer of tissue where they started. This term is most often used to describe early-stage cancers or pre-cancerous conditions, but it also applies to all benign …

Gastric dysplasia (also called glandular intraepithelial neoplasia) is a precancerous change that affects the inner lining of the stomach. In gastric dysplasia, the cells that normally cover the stomach wall begin to look and behave abnormally, but they have not yet spread into deeper layers of the stomach. Gastric dysplasia can remain stable for years, …

What is squamous dysplasia? Squamous dysplasia is a precancerous change involving an area of the body covered by squamous cells. If left untreated, squamous dysplasia can turn into a type of cancer called squamous cell carcinoma over time. What causes squamous dysplasia? The cause of squamous dysplasia depends on where in the body the disease …

Adenocarcinoma in situ (AIS) is a medical term used to describe an early form of gland-forming cancer. The word “adenocarcinoma” refers to a type of cancer that develops from glandular cells. The phrase “in situ” means “in its original place.” Together, adenocarcinoma in situ means that the cancer cells are present but have not yet …

Adenocarcinoma in situ (AIS) of the cervix is a precancerous condition in which abnormal glandular cells grow on the surface of the cervix. These abnormal cells look like those seen in adenocarcinoma, a type of cervical cancer, but in AIS, the abnormal cells are confined to the surface layer and have not invaded deeper tissues. …

High grade dysplasia of the larynx, also known as severe keratinizing squamous dysplasia, is a precancerous condition involving the abnormal growth of squamous cells lining the larynx (voice box). Dysplasia means the cells look abnormal when viewed under a microscope and are not developing normally. If left untreated, high grade dysplasia can progress to a …

Endometrioid intraepithelial neoplasia (EIN) is a precancerous condition that affects the lining of the uterus, called the endometrium. In this condition, the glands that make up the endometrium become abnormal in both number and appearance, causing the tissue to become thicker than normal. It is called a precancerous condition because over time, EIN can develop …

Background: Oral epithelial dysplasia (OED) is a precancerous condition characterized by abnormal changes in the epithelial cells lining the oral cavity. These changes indicate that the cells are growing and maturing abnormally, which can potentially progress to oral squamous cell carcinoma if not properly managed. Oral epithelial dysplasia can appear as white patches (leukoplakia), red …

Low grade squamous intraepithelial lesion (LSIL) is an abnormal growth caused by infection with human papillomavirus (HPV). The abnormal growth seen in LSIL is an example of dysplasia. It commonly involves the cervix, vagina, vulva, penis, or anal canal. This condition may affect both women and men. The virus infects squamous cells found on the …
