Multi-Gene Cancer Panel Genetic Testing: Why More May Not Always Be Better

The advent of multi-gene cancer panel testing has dramatically altered the landscape of germline cancer genetic testing. An increasing number of patients are being tested for genes beyond just high-risk, well-established culprits such as BRCA1/2 and the mismatch repair genes associated with Lynch syndrome.  While broadening the scope of genetic testing allows for the increased detection of mutations overall, it is important to consider the value this information may or may not offer to individual patients as well as the possible limitations and drawbacks of expanded testing.
