hyperplasia
Too many cells
Hyperplasia is the abnormal increase in the number of cells in a tissue or organ, causing it to enlarge.
Unlike hypertrophy, where existing cells grow larger, hyperplasia involves actual cell multiplication.
The condition can be benign or precancerous: The biopsy revealed endometrial hyperplasia.
Hyperplasia may result from hormonal stimulation, chronic irritation, or other factors that trigger cell division.
