There are three layers in our skin – the epidermis is the outer layer, the dermis is the next layer and the hypodermis is the deepest layer. Melanomas are ranked by levels, which refers to the cancer’s depth of skin penetration. An in situ or Level 1 melanoma is located in the epidermis, Levels II, III and IV melanoma are found in the dermis and Level V melanoma occurs in the hypodermis.
Melanoma is the most aggressive form of skin cancer and can grow rapidly when left untreated. For this reason, it’s crucial to consult your doctor or dermatologist about any lesions which cause concern.
