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. Currently, the standard Breslow's depth has been replaced by the AJCC depth, in the AJCC staging system of melanoma. Originally, Breslow's depth was divided into 5 stages.
