A red nevus usually refers to a cherry angioma, a common benign acquired hemangioma. A red nevus on the chest usually needs no treatment, but those with large skin lesions can be removed by high-frequency electrocautery excision, liquid nitrogen freezing, laser and so on. Cherry angiomas generally have no obvious symptoms to health, and patients mostly have no self-conscious symptoms, so they can be treated without special treatment. However, for those with large skin lesions, if necessary, the skin lesions can be excised by high-frequency electric knife, and liquid nitrogen freezing can be used to make the localized skin lesions form blisters, and the purpose of treatment can be achieved after the blisters have scabbed and fallen off. In addition, the skin at the treatment site can also be sterilized and local anesthesia, and the skin lesions can be removed through laser treatment, which can achieve clinical cure. It is recommended that those who have red moles on the chest and have the need for treatment should go to a regular medical institution for consultation and treatment. Avoid picking and scratching with hands, so as not to cause local bleeding or even induce infection.
