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 ...
A localized disease is an infectious or neoplastic process that originates in and is confined to one organ system or general area in the body, [1] such as a sprained ankle, a boil on the hand, an abscess of finger.
Dysplasia is often indicative of an early neoplastic process. The term dysplasia is typically used when the cellular abnormality is restricted to the originating tissue, as in the case of an early, in-situ neoplasm .
Invasion is the process by which cancer cells directly extend and penetrate into neighboring tissues in cancer. [1] It is generally distinguished from metastasis, which is the spread of cancer cells through the circulatory system or the lymphatic system to more distant locations. Yet, lymphovascular invasion is generally the first step of ...
Malignant transformation is the process by which cells acquire the properties of cancer. This may occur as a primary process in normal tissue, or secondarily as malignant degeneration of a previously existing benign tumor .
If the general process by which sporadic colon cancers arise is the formation of a pre-neoplastic clone that spreads by natural selection, followed by formation of internal sub-clones within the initial clone, and sub-sub-clones inside those, then colon cancers generally should be associated with, and be preceded by, fields of increasing ...
According to neoplastic principles, [27] [28] every work of art (painting, sculpture, building, piece of music, book, etc.,) is created intentionally. It is the product of a series of aesthetic choices and, to a lesser extent, of what the work of art represents.
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells.Cell division is a normal process used by the body for growth and repair.
