    Hyperplasia

    Hypergenesis

    Hyperplasia is increased cell production in a normal tissue or organ. Hyperplasia may be a sign of abnormal or precancerous changes. This is called pathologic hyperplasia.

    It can also be due to the increased growth of normal cells. This is called physiologic hyperplasia. An example of physiologic hyperplasia is an increase in the number of prostate cells most often seen in older men (benign prostatic hyperplasia).
