In medicine , Breslow's depth was used as a prognostic factor in melanoma of the skin. It is a description of how deeply tumor cells have invaded. Originally, Breslow's depth was divided into 5 stages. Depth of invasion was first reported as a prognostic factor in melanoma by the pathologist Alexander Breslow, M.
