Every person considering cancer predisposition testing should have the opportunity to receive appropriate information and genetic counseling. Testing decisions are not only highly personal - they can also be permanent. Testing decisions may be easier in the future, as the options improve for those found to carry a gene mutation. Better treatment, early detection, and even prevention strategies based on our knowledge of how these genes are linked to cancer are on the way. Knowledge can be empowering when it helps to cope more effectively with a situation.
Genetic testing can provide that for some families.
However, genetic test results are powerful and can have the opposite effect. Anxiety, despair, and fear of the future and the possibility of genetic discrimination may await those who would be better off not knowing. Skilled genetic counseling is not just for individuals and families where a gene mutation has been found. It should be offered before as well as after testing so that thoughtful and personal decisions can be made about whether receiving this powerful insight to future health risks will be of benefit or not.
