Hyperplasia? - Answers

Hyperplasia refers to an increase in the number of cells in a tissue or organ, resulting in its enlargement. This growth is primarily due to an increase in cell division rather than cell size. Hyperplasia can be physiologic, as seen during organ development or pregnancy, or pathologic, occurring in response to various stimuli or disease conditions. It often leads to organ swelling or thickening and can have functional implications depending on the specific tissue affected. Some notable examples of hyperplasia include endometrial hyperplasia in the uterus, prostatic hyperplasia in the prostate, and lymphoid hyperplasia in lymph nodes. Understanding the underlying causes and mechanisms of hyperplasia is important in managing related health conditions.
