Stage 0 melanoma (melanoma in situ or MIS) is confined to the epidermis, which is the top layer of skin. At this stage, the cancer has not spread beyond this layer, which is why it has a 100% five-year survival rate when properly treated.

By definition, stage 0 melanoma has not spread - if melanoma cells are found beyond the epidermis (top layer of skin), it would be classified as a more advanced stage of melanoma. If you're concerned about potential spread, it's important to have regular follow-up appointments with your healthcare provider. The standard treatment for stage 0 melanoma is surgery to remove the affected area, which is typically very effective at preventing any progression of the disease.
