Keloid hyperplasia (irregular medical term: hyperplasia) caused by a mole on the neck can be treated by topical cream, local injection, laser, surgery and so on. 1. Topical cream: topical ointment such as Mucopolysaccharide polysulfate cream can be used to soften the scar and reduce the scar hyperplasia. 2. Local injection: mild hyperplasia can be injected subcutaneously with hormone drugs, which can relieve it to some extent. 3. Laser: laser treatment can be used to close the small blood vessels under the scar or flatten the hyperplasia. 3. Surgery: larger scar hyperplasia requires surgery, fine suture after excision, and with local superficial X-ray radiation therapy. Moles on the neck caused by keloid hyperplasia suggest timely consultation, under the guidance of the doctor to carry out targeted treatment, to avoid adverse consequences.
