Moles on the face may become raised due to inflammation and infection, cancer or proliferation of nevus cells. 1. Inflammation and infection: a raised mole on the face may be related to local infection, which will lead to localized lesions appearing raised, and even localized redness, swelling, pain and other symptoms. 2. Cancer: if the mole on the face is stimulated for a long time, it may lead to cancer, which will make the mole increase in size in a short period of time, and there will be localized ulceration, pus and other symptoms, which will also lead to the mole becoming raised, and there may be localized enlargement of lymph nodes. 3. Nevus cell proliferation: the proliferation of local nevus cells, such as the growth of nevus cells of junctional nevus to the dermis layer, may appear mixed nevi, resulting in the nevus on the face becoming raised. If the mole on the patient’s face becomes raised, it is recommended to go to the hospital in time for a clear diagnosis and early and regular treatment.
