Nevus in medical terms refers to pigmented nevus, melanocytic nevus. The common treatments for moles are physical therapy, surgery, etc. The specific treatment method should be determined by the doctor after comprehensive analysis based on the size, location and depth of the nevus. Nevus is a common benign skin tumor composed of pigment-containing nevus cells, which is divided into acquired and congenital, and is related to ultraviolet radiation and family genetics. Acquired ones are less likely to be malignant and require regular follow-up, and generally do not require treatment. However, for those with cosmetic needs, they can be removed by cryotherapy and laser treatment. For patients with acquired and suspected malignant lesions, they can be surgically removed and pathologically examined. In addition, chemical peeling is also effective in treating nevi. The vast majority of acquired patients do not require treatment. For those with cosmetic needs or suspected malignant lesions, the prognosis is generally good through active and regular treatment. Patients with a lot of nevi should choose regular medical institutions for examination and treatment. In daily life, you need to pay attention to skin protection to avoid skin irritation or damage.
