What is the definition of carcinoma in situ?
Carcinoma in situ (CIS) is a group of abnormal cells that are found only in the place where they first formed in the body (see left panel). These abnormal cells may become cancer and spread to nearby normal tissue (see right panel).
How serious is carcinoma in situ?
These in situ cells are not cancer, but they could become malignant. If they do this, they can start to invade other tissues. For this reason, a doctor will recommend treatment to remove the cells. This will reduce the risk of cancer developing later.
Is carcinoma in situ reversible?
Precancer progresses through dysplastic phases to carcinoma in situ and these changes can be documented by aneuploidy in the abnormal cells. Some of all these degrees of dysplasia, including carcinoma in situ, have been shown to be reversible.
