The difference between tumor hyperplasia and inflammatory hyperplasia mainly lies in that inflammatory hyperplasia is controlled by the organism, and its probability of malignant transformation is very low, while tumor hyperplasia is not controlled by the organism, and it has already formed a tumor and is easy to deteriorate. 1. Inflammatory hyperplasia: controlled by the body, with the biological characteristics of normal cells, manifested as thickening and enlarging of local tissues without forming tumors, which belongs to diffuse inflammation, and the probability of malignant transformation is relatively low under normal circumstances. 2. Tumorigenic hyperplasia: it is not controlled by the organism and loses the biological characteristics of normal cells, manifesting itself as chaotic growth of cells and increasing density of tissue cells, which has already formed a tumor and is prone to malignant transformation, and may also metastasize after malignant transformation, seriously impairing the function of the tissues and organs in the area where it grows. If the diagnosis of tumor hyperplasia is confirmed, patients need to be actively treated as soon as possible to avoid malignant changes.
