Information of a single cell into a multicellular, malignant tumor. In most cases, this is believed to involve a permanent , irreversible change, probably consisting of a genetic mutation. Once initiation has begun , the cell has the potential to develop into a tumor , provided that the other essential steps of Carcinogenesis take place. If these other steps do not take place, the initiated cell may remain dormant indefinitely with no apparent effect on the organism. 2. Promotion(the second stage of carcinogenisis) During this carcinogenisis stage , the initiated cell clones itself and expands within a given tissue, As the number of these target cells increases, there are many sites where changes can produce fully malignant cells. ...
