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 …

What does gastric dysplasia mean? Gastric dysplasia is a precancerous change that can turn into a type of stomach cancer called adenocarcinoma over time. Another name for this condition is glandular intraepithelial neoplasia. Where in the stomach does dysplasia start? Gastric dysplasia in the stomach starts from specialized epithelial cells that cover the inside surface …

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 non-invasive type of cancer. It is called non-invasive because the cancer cells have not spread into surrounding tissues. If left untreated, it can turn into invasive adenocarcinoma. Is adenocarcinoma in situ a benign or malignant disease? AIS is considered a malignant (cancerous) disease. However, it is also non-invasive which …

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 …

It is considered a precancerous condition because over time it can turn into a type of endometrial cancer called endometrioid adenocarcinoma. Another name for this condition is atypical endometrial hyperplasia. Is endometrioid intraepithelial neoplasia cancer? No. …

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 …

In pathology, the term precursor is used to describe any non-cancerous condition that has the potential to turn into cancer over time. Precursor diseases can be caused by viruses, genetic changes, or environmental factors such as smoking or excessive alcohol consumption. The chance that a precursor will eventually turn into cancer depends on many factors …
