What does Level 3 melanoma mean?

What does anatomic Clark level mean?
Clark level of invasion: A method for determining the prognosis (outlook) with melanoma. The method was devised by the pathologist Wallace Clark and measures the depth of penetration of a melanoma into the skin according to anatomic layer.
What is Clark’s Level 2 melanoma?
Clark’s Level II: Penetration by melanomas into the second layer of the skin, the dermis. Clark’s Levels III-IV: Melanomas invade deeper through the dermis, but are still contained completely within the skin.
What is the life expectancy of someone with melanoma?
The overall average 5-year survival rate for all patients with melanoma is 92%. This means 92 of every 100 people diagnosed with melanoma will be alive in 5 years. In the very early stages the 5-year survival rate is 99%. Once melanoma has spread to the lymph nodes the 5-year survival rate is 63%.

What is Clark Level 2?
Clark’s Level II means it has moved from the epidermis into the top layer of the dermis, nothing more. Usually this lesion would be very thin, but the path report is needed to confirm that. A sentinel node biopsy may or may not be done, again depending on the factors I listed above.
