A neoplasm (/ ˈ n iː oʊ p l æ z əm, ˈ n iː ə-/) [1] [2] is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia. The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger is ...
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases.
For example, a lipoma is a common benign tumor of fat cells , and a chondroma is a benign tumor of cartilage-forming cells (chondrocytes). Adenomas are benign tumors of gland-forming cells, and are usually specified further by their cell or organ of origin, as in hepatic adenoma (a benign tumor of hepatocytes, or liver cells).
The former series details the concepts, issues, and trends surrounding the information economy, society and polity. It intends to raise awareness and help policy makers and planners understand the relevance of information and communications technology (ICT) for development, by explaining technical jargon in simple terms.
Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications [1] and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users to access, store, transmit, understand and ...
A "false" mixed tumor contains one type of neoplastic cells, but which have more than one appearance. For example, benign pleomorphic salivary gland tumors may have some tumors cells that form pseudocartilage. Yet, all the tumor cells have similar myoepithelial profile on immunohistochemistry, and are thus classified as one cell type.
Cancers and tumors are caused by a series of mutations. Each mutation alters the behavior of the cell somewhat. Each mutation alters the behavior of the cell somewhat. Carcinogenesis , also called oncogenesis or tumorigenesis , is the formation of a cancer , whereby normal cells are transformed into cancer cells .
Recent changes in ICT use globally have damaged the environment (in terms of waste and energy consumption etc.) but also have the potential to support environmental sustainability activities, [2] such as the targets set within the Millennium Development Goal (MDG) number 7 (MDG7) to "ensure environmental sustainability".
