Full body skin screening involves examining the entire body from head to toe. Moles are evaluated, as well as other skin lesions and signs of sun damage. Basal cell and squamous cell skin cancers often present as bleeding sores or persistently scaly spots that do not heal. Melanoma can present as a new or changing pigmented lesion. In the office, a hand-held device called a dermatoscope is used to examine each lesion up close. At home, perform regular self-exams, noting non-healing sores and brown/black spots that have (A) Asymmetry, (B) Irregular borders, (C) Mixes or changing colors, (D) Diameter >0.6cm and (E) Evolution or noticeable changes. These lesions could require a skin biopsy.
