Hyperplasia
Make it clearer
Hyperplasia occurs when a tissue accumulates extra cells because they are multiplying more than usual. The main change is the number of cells.
Picture a wall with more bricks, but with the bricks still orderly and normal-looking. Similarly, cells and tissue organization may look normal under a microscope in hyperplasia. Hyperplasia is not cancer. Some types can progress and others cannot, so they do not all carry the same risk.
In brief
Hyperplasia is an increase in the number of cells in a tissue because the cells multiply more than usual and additional cells accumulate.
In hyperplasia, the cells and tissue organization may still look normal under a microscope. Hyperplasia is not cancer, and whether it can progress to cancer depends on the type.
Picture a wall with more bricks than usual, but with the bricks still orderly and normal-looking.
