Melanoma is a type of skin cancer originating from the pigment producing cells in the skin called melanocytes. Though not as common as basal cell carcinoma and squamous cell carcinoma, it is more deadly because of its ability to spread to other parts of the body. Melanomas can have various appearances. The ABCDEs and Ugly Duckling Sign are two commonly used methods to help identify melanomas. As early detection and treatment are crucial for improving survival, any new, unusual, changing, or symptomatic growth should prompt a visit to your dermatologist.
