A sudden growth of a mole under the chin usually has no effect.
Moles are also called pigmented nevi, which are generally related to genetic factors and can grow at any age and in any part of the body. Most of them are benign, which are not harmful to the body and do not need any treatment.
However, if the mole has ulcers for a long time, or has repeated inflammation for a long time, or suddenly grows and protrudes, it is necessary to further check the possibility of melanoma, and it is recommended to do pathological examination clinically, and if melanoma is diagnosed, it is recommended to surgically remove it and have it treated with chemotherapy.
If there is no possibility of melanoma, but it affects the aesthetics, it can be removed by laser, and it is recommended to go to the dermatology and cosmetology departments of regular medical institutions for treatment.
