The Clark and Breslow thickness scales describe how deeply the melanoma has gone into the skin. Find out more about these staging systems and how doctors use them.
The Breslow Depth is a helpful measure of how far melanoma has invaded the body and the Clark Level is a staging system that describes the depth of melanoma as it grows in the skin.
Note: It is important to note that while AJCC staging is used to help understand how far the melanoma has advanced through the body, other measures known as the Breslow Depth and the Clark Level relate to the specific melanoma biopsied, and the depth or thickness of that melanoma.

Nov 20, 2000 · A recent proposal to eliminate Clark level from the staging system for melanoma of the American Joint Committee on Cancer (AJCC) prompted the authors to investigate whether level adds useful prognostic information to Breslow thickness.
