Carcinoma in situ (CIS) is a pre-malignant condition, in which some cytological signs of malignancy are present, but there is no histological evidence of invasion through the epithelial basement membrane. Carcinoma in situ (CIS is an early form of Carcinoma defined by the absence of invasion of surrounding tissues The basement membrane is a structure that supports overlying Epithelial or Endothelial cells.

Classification of carcinoma

Carcinoma, like all neoplasia, is classified by its histopathological appearance. Adenocarcinoma and squamous cell carcinoma, two common descriptive terms for tumors, reflect the fact that these cells may have glandular or squamous cell appearances respectively. Adenocarcinoma is a cancer that originates in Glandular tissue In Medicine, squamous cell carcinoma (SCC is a form of Cancer of the Carcinoma type that may occur in many different organs including the Skin See also Cancer A tumor or tumour is the name for a swelling or lesion formed by an abnormal growth of cells (termed neoplastic A gland is an organ in an animal's body that synthesizes a substance for release such as Hormones or Breast milk, often into the Bloodstream Severely anaplastic tumors might be so undifferentiated that they do not have a distinct histological appearance (undifferentiated carcinoma). Hyperplasia Hypertrophy Carcinoma Sarcoma Hyperplasia an increase in the number of cells in an organ or tissue which usually leads to an increase in the size of the tissue or organ Hypertrophy

Sometimes a tumour is referred to by the presumptive organ of the primary (eg carcinoma of the prostate) or the putative cell of origin (hepatocellular carcinoma, renal cell carcinoma). Hepatocellular carcinoma (HCC also called hepatoma) is a primary malignancy (cancer of the Liver. "Kidney Cancer" redirects here For Wilms' Tumor/Nephroblastoma see Wilms' tumor.

Staging and grading

The staging of cancers is the extent of spread of the neoplasm. Grading is the system used to record the tumors degree of differentiation from the parent tissue. High grade shows little differentiation and the prognosis is therefore poor.

Carcinomas, like all cancers, are staged according to the extent of disease. The UICC/AJCC TNM system is often used, however for some common tumors, classic staging methods (such as the Dukes classification for colon cancer) are still used. The TNM Classification of Malignant Tumours ( TNM) is a Cancer staging system that describes the extent of Cancer in a patient’s body Colorectal cancer, also called colon cancer or large bowel cancer, includes Cancerous growths in the colon, Rectum and
