hyperplasia
This term describes a quantitative increase in cell number rather than an increase in the size of individual cells. It is a clinical observation of growth that can be a normal response to a stimulus, such as the growth of the uterus during pregnancy, or a pathological process. In a medical context, the word carries a neutral to cautious tone. While hyperplasia is not the same as neoplasia (cancer), it often serves as a precursor or a marker for potential dysfunction, making it a critical focal point for diagnostic screening and biopsies.
Countable when referring to specific types of the condition, such as endometrial hyperplasia. Uncountable when referring to the biological process of cellular overgrowth in general.
Meanings
The enlargement of an organ or tissue caused by an increase in the reproduction rate of its cells.
