Many skin lesions or growth are common and benign (not cancerous), but may be uncomfortable or unsightly. Moles are skin growths that are usually brown or black, and can appear anywhere on the skin, alone or in groups. They may grow dark with time or have hair growth on them. If you would like to have a mole removed, our doctors use procedures like freezing and excision to safely remove the mole. Cryotherapy is a procedure for super-freezing tissue in order to destroy abnormal or diseased tissues, like warts, skin tags, moles, etc. using a very cold substance like liquid nitrogen.
