The two most important distinguishing features of tumorigenic hyperplasia and inflammatory hyperplasia are as follows: 1. Inflammatory hyperplasia: tumor cells lose their normal tissue cell characteristics, and inflammatory hyperplasia. The proliferating cells here still have the biological characteristics of normal cells. 2. Tumorigenic hyperplasia: the cells are growing completely endlessly, the density in the middle of tissue cells keeps increasing, and metastasis occurs, and keeps growing endlessly. Inflammatory hyperplasia, on the other hand, does not grow endlessly. Inflammatory hyperplastic cells are subject to energetic regulation, and although they are accompanied by inflammation and even some edema, the cell increase to a certain level of growth will stop, and these are controlled by the organism. In conclusion, tumorigenic proliferation is not controlled by the organism, i.e., it is endless, and the cells and tissues are all disorganized, which will seriously damage the function of the organs and tissues at the site of growth, and these can be clarified by biopsy of pathology.
