Moles, also known as dark pigmented nevi, do not usually go away on their own. Nevus pigmentosus is a relatively common type of skin tumor, the disease is not self-limiting, so it will not go away by itself. Nevus melanosus usually grows slowly and does not cause serious impact on the body except affecting aesthetics. A very small number of nevi may undergo malignant transformation and become melanoma when exposed to adverse stimuli. Nevus will not dissipate on its own, so when it affects aesthetics or changes in size and shape abnormally, it needs to be treated in time, and its main treatments include laser treatment, cryotherapy, and surgical excision treatment. After the appearance of nevus, we must pay attention to the observation, at the same time, try to avoid excessive stimulation, if necessary, under the guidance of the doctor for standardized treatment.
