Risk of Melanoma in BRCA1/2 Carriers

Over the last few years, there has been mixed information about the risk of melanoma in BRCA1/2 carriers – while earlier studies had suggested an association,1,2 other studies showed no association.3,4 Thus, based on current evidence, it is unclear if BRCA1 and/or BRCA2 pathogenic variants increase melanoma risk based on the current evidence.5,6 However, more recently, a study, which included ICARE participants, reported that compared to 1.5% in the general population, the risk of melanoma may be slightly higher in BRCA1 carriers (2.5%) and BRCA2 carriers (2.3%).7 Ultimately, given it is reasonable to do a regular skin exam in the general population, this suggestion certainly holds in individuals with a BRCA1 or BRCA2 mutation as well.
