According to the photos, it is not excluded that the mole has mutated after long-term stimulation. The possibility of malignant transformation is not ruled out, but the diagnosis depends on pathological examination. The old man is old and has many basic diseases, but he still needs active surgery. Even if it is malignant, it may be low-grade, slow in progress, or not spread in the early stage. It's a pity to give up at this time. If the old man is carefully prepared, he can still endure the operation. Active surgical treatment is recommended. Pathological examination was performed after tumor resection. The operation is not very troublesome, so it is recommended to find a plastic surgeon, so that the appearance of the postoperative repair will be better. The cost should be less than 1000 yuan, which varies from place to place.

(Dr. Zhang Jixun from the Second Hospital of Shanda University solemnly reminds me that because I can't see the patient face to face, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
