What is hyperplasia?

Hyperplasia refers to a condition in which there is an increase in the number of cells in a tissue or organ, leading to its enlargement. This cellular proliferation can occur in response to various stimuli, such as hormonal changes or increased demand on the tissue. Unlike cancer, which involves uncontrolled cell growth, hyperplasia typically involves a regulated increase in cell numbers.

In choosing excessive cell formation as the answer, one highlights that hyperplasia is a normal physiological process that occurs in certain conditions, such as during the menstrual cycle in the endometrium or in the prostate gland in response to hormonal changes. It is important to note that hyperplasia can be a benign condition, distinguishing it from malignant conditions. This understanding is fundamental in the study of tissue response and pathology in fields such as electrolysis and laser treatments, where changes in skin and tissue types can be influenced by various factors.
