Clark LevelNone

Clark Level is a staging system used to describe how deeply melanoma skin cancer has invaded the layers of the skin. "None" in Clark Level indicates that the melanoma has not penetrated beyond the outermost layer, called the epidermis. Essentially, this means the cancer is confined to the very surface of the skin and has not invaded deeper tissues. This early stage usually suggests a more favorable prognosis and often requires less aggressive treatment. In summary, Clark Level None indicates the melanoma is just on the surface, with no invasion into underlying skin layers.
