Moles generally refer to pigmented nevi also known as melanocytic nevi, which are benign skin tumors of melanocytic origin. Moles on the chest can be removed by laser or surgical excision. 1. Laser removal: mainly according to the theory of selective photothermal effect of laser, using the instantaneous generation of high-intensity radiation energy, focusing on the black quality of pigmented tissue particles, direct crushing and refinement, and then discharged from the body through the lymphatic tissues, so as to achieve the purpose of removing moles. 2. Surgical excision: those with malignant tendency should be surgically excised as early as possible, and at the same time, histopathological examination should be done. It is recommended that patients should go to regular hospitals and take targeted treatment under the guidance of doctors.
