However, a melanocytic nevus is benign, and melanoma is malignant. Most melanocytic nevi never evolve into a cancer, with the lifetime risk for an individual nevus being 1 in 3000 for men and 1 in 11 000 for women. [5] Moreover, dermatologists have a standardized system for determining whether a skin lesion is suspicious for malignant melanoma.
The earliest stage of melanoma starts when melanocytes begin out-of-control growth. Melanocytes are found between the outer layer of the skin (the epidermis) and the next layer (the dermis). This early stage of the disease is called the radial growth phase, when the tumor is less than 1 mm thick, and spreads at the level of the basal epidermis ...
