WebBreslow's depth. 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 Currently, the standard Breslow's depth has been replaced by the AJCC depth, in the AJCC staging system of melanoma.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. Web1 Answer. Yes, it probably shouldn't be used as an estimate of hazard, and as Elvis points out the rest of the paper notes that Breslow didn't really intend it for that purpose.
