Carcinoma in situ definition

Carcinoma in situ means cancer in which the tumor cells still lie within the tissue of the site of origin without having invaded neighboring tissue.

Carcinoma in situ means a group of abnormal cells found only in the place where they first formed in the body.

Carcinoma in situ means cell changes in which malignant cells are localized and may press against adjoining tissue but have not penetrated or spread beyond their site of origin.
