Is a mass found in the maxillofacial region always a tumor? The answer is no. Because many non-neoplastic diseases can also appear in the form of lumps. For example, the most common is the inflammation of the maxillofacial region, which can cause acute or chronic lymphadenitis, so that the local lymph nodes become enlarged, as well as parasitic diseases (such as schistosomiasis), maxillofacial deformities or hard and soft tissue hyperplasia and other diseases can be in the form of maxillofacial masses, but not tumors. Therefore, although we emphasize that early detection and correct diagnosis is the key to cure malignant tumors, and we are required to be alert to the new organisms or masses in the maxillofacial region, but there is no need to be afraid of seeing the “bag”, after all, the “bag” is not equal to the “tumor”. After all, “lump” is not equal to “tumor”.
