<unk>  (or "hypergenesis") is a general term referring to the proliferation of cells within an organ or tissue.<unk>  may result in the gross enlargement of an organ, the formation of a benign tumor.<unk>  is considered to be a physiological response to a specific stimulus, and the cells of a hyperplastic growth remain subject to normal regulatory control mechanisms. This stands in contrast to neoplasia (the process underlying cancer and some benign tumors), in which genetically abnormal cells proliferate in a non-physiological manner which is unresponsive to normal stimuli.
