- The absence of a BRCA1 or BRCA2 mutation means that the person tested is not in the high risk group for breast and/or ovarian cancer related to the BRCA gene.The person's risk of developing either of these cancers is the same as that of the general population.enetic testing for just BRCA1 or BRCA2 will only detect mutations in these two genes; therefore, if a mutation is present in another gene known to cause an increased risk for breast cancer, BRAC1 / BRCA2 testing will not detect it.
