The ABCDE Rule originally described by Friedman et al. it is now included in The American Cancer Society’s The Seven Warning Signals of Cancer and is a simple method that allows you to identify a nevus at risk.<\/p>\n

This method takes into account the macroscopic characteristics of a nevus. If two or more parameters are identifiable on the nevus, it can be considered at risk. It is therefore believed that it is an easy-to-apply method that allows the general practitioner or often the patient himself to identify nevi at risk to be subjected to dermatological evaluation.<\/p>\n
