Medical Intelligence & Overview
Carcinoma in situ (CIS) of the lip, oral cavity, and pharynx is an early form of cancer that is confined to the surface layer of cells in these regions. The term 'in situ' indicates that the malignant change is localized and has not yet invaded deeper tissues or spread to other parts of the body. Recognizing and diagnosing this condition early is crucial, as it has the potential to be treated effectively and prevent progression to more advanced, invasive cancers.
