What does genetic testing for breast cancer risk involve?

Genetic testing should always include genetic counseling -- a face-to-face discussion with a genetics professional, both before and after the actual test. The important thing is the information you gain from the test, how you use the information, and having proper interpretation by a professional. Genetic testing is usually done via a blood test. No special fasting is needed. Insurance companies usually cover the cost when testing is indicated, and usually you would know what charges you'd face beforehand. Often it is better to first test someone in the family who has been affected by cancer -- rather than starting with someone unaffected -- for better information from the test result.

Technically, genetic testing for breast cancer just involves giving either a blood or saliva sample. The sample is then sent to a genetic testing laboratory where they read the genetic code of which ever gene you are being evaluated for. Genetic testing generally takes 2-3 weeks to get the results back and most insurance companies cover the cost depending on the gene being tested for. Most genetic testing is coordinate through a genetics professional and you can find a genetic counselor at the following website: http://www.nsgc.org/FindaGeneticCounselor/tabid/64/Default.aspx
