The term "pre-cancer" has also been used.These abnormal cells grow in their normal place thus "in situ" (from Latin for "in its place"). For example, carcinoma in situ of the skin, also called Bowen's disease, is the accumulation of dysplastic epidermal cells within the epidermis only, that has failed to penetrate into the deeper dermis. For this reason, CIS will usually not form a tumor. Rather, the lesion is flat (in the skin, cervix, etc.) or follows the existing architecture of the organ (in the breast, lung, etc.). Exceptions include CIS of the colon (polyps), the bladder (pre-invasive papillary cancer), or the breast (ductal carcinoma ''in situ'' or lobular carcinoma in situ).Many forms of CIS have a high probability of progression into cancer, and therefore removal may be recommended; however, it is well-known that progression of CIS is highly variable and not all CIS becomes invasive cancer.In the TNM classification, carcinoma in situ is reported as TisN0M0 (Stage 0)."@en }
