Cancer Genetics Risk Assessment and Counseling (PDQ®): Genetics - Health Professional Information [NCI] - The Option of Genetic Testing

Table 1. Clinical Utility of Genetic/Genomic Testsa continued...

When a test result is negative, the posttest session may be briefer. It is important, however, to discuss genetic, medical, and psychological implications of a negative result in a family with a known mutation. For example, it is essential that the person understand that the general population risks for relevant cancer types still apply and that the person's individual risk of cancer may still be influenced by other risk factors and family history from the other side of the family. Furthermore, people may be surprised to feel distress even when a test is negative. This outcome has been documented in the context of BRCA1/2 mutation testing [90] and may also be anticipated in other cancer susceptibility testing. Posttest results discussion of such distress may lead to referral for additional counseling in some cases.

Many individuals benefit from follow-up counseling and consultation with medical specialists after disclosure of test results. This provides an opportunity for further discussion of feelings about their risk status, options for risk management including screening and detection procedures, and implications of the test results for other family members.
