How are you? Risk factors for skin cancer include: fair skin, history of sunburns, a close relative with skin cancer or presence of atypical and more than 50 moles. It is important to know the ABCDEs of Melanoma: asymmetry, border, color, diameter, and evolving mole. A mole or skin lesion that looks different from the rest or is changing in size, shape, or color needs to be evaluated further by a dermatologist.

Take care and best regards.
