Cancer that involves only the top layer without invading deeper tissues.
A very early stage of cancer that is still confined to the site where it first developed. The disease has not invaded other parts of the organ or spread to distant parts of the body.
An early stage of cancer, in which the tumor is still only in the structures of the organ where it first developed, and the disease has not invaded other parts of the organ or spread (metastasized). Most in situ carcinomas are highly curable.
Pronunciation: (KAR-si-NO-ma in SYE-too) Cancer that involves only cells in the tissue in which it began and that has not spread to nearby tissues. For example, in the breast, ductal carcinoma in situ (DCIS) means cancer cells that are confined to the duct and have not invaded surrounding tissue.
Lung cancer that is found only in the layer of cells lining the air passages.
a cluster of malignant cells that has not yet invaded the deeper epithelial tissue or spread to other parts of the body
A neoplasm in which the tumor cells are confined by the basement membrane to the epithelium of origin.
An early stage of cancer in which tumor cells have not yet invaded surrounding tissues.
An early stage in development, when the cancer is still confined to one layer of tissue. In situ carcinomas are highly curable.
the earliest stage of cancer in which young tumour cells have not yet invaded surrounding tissues.
A cancer that has not spread to other parts of the body or invaded nearby tissue. Carcinoma in situ, an early form of cancer, is highly curable.
A high grade abnormality confined to the squamous cell epithelial layer of the cervix. Without treatment it may develop into invasive cancer. This is synonymous with CIN-3
Breast cancer that is contained and has not spread outside of the duct or lobule.
Cancer "in one place". A CIS has not spread to other parts of the body. Some will go away by themselves. Others can be cured by stripping or cutting away the cell's lining. Some are destroyed by laser beam. If CIS is not treated, it can spread.
Carcinoma that is still limited to an epithelial surface (i.e. has not invaded through the basement membrane or developed potential to spread to distant sites).
A malignant tumour that is confi ned to its original site.
The earliest stage of cancer, in which the tumor is still confined to the local area, before it has grown to a significant size or has spread. In situ carcinomas are highly curable.
(KAR-sih-NOH-muh in SYE-too) Cancer that involves only cells in the tissue in which it began and that has not spread to nearby tissues.
An early cancer that has not invaded (grown into) surrounding tissues.
Cancer that involves only the cells in which it began and that has not spread to other tissues.
A malignant tumour which has not yet become invasive but is confined to the layer of cells from which it arose. A form of pre-invasive cancer.
The most severe stage of epithelial dysplasia, involving the entire thickness of the epithelium, with the epithelial basement membrane remaining intact.
A non-cancerous tumor that remains 'in the site' of origin and shows signs of becoming cancerous.
a malignant [cancerous] tumour that is confined to its original site.
(kar-sin-O-ma in SYE-too): Cancer that involves only the cells in which it began and has not spread to neighboring tissues.
An abnormal growth of cells that stays within the area in which it started and has not spread to other parts of the body.
early stage cancer when it is confined to the place where it started
cancer that involves only the tissue in which it began; it has not spread to other tissues.
tumours that are flat and solid, and appear to grow directly on the lining of the bladder wall
Describes a condition in the earliest stage; also known as precancerous, or stage 0.
Cancer that is confined to the cells where it began, and has not spread into surrounding tissues.
cancer cells which are restricted to a very local area. The abnormal cells are evident throughout each of the layers of the epithelium but they have not extended into other tissue or surrounding areas.
Cancer that involves only the place in which it began and that has not spread. Carcinoma in situ is an early-stage tumor. See the entire definition of Carcinoma in situ
The earliest stage of cancer where the cancer is still confined to the tissue in which it started.
Carcinoma in situ (CIS) is an early form of carcinoma defined by the absence of invasion of surrounding tissues. In other words, the neoplastic cells proliferate in their normal habitat, hence the name 'in situ' (Latin for 'in its place'). For example, carcinoma in situ of the skin, also called Bowen's disease is the accumulation of neoplastic epidermal cells within the epidermis only.
