What are the potential problems with genetic testing?

ANSWER

Genetic testing is not 100% accurate. If a test is negative, a person still has a chance of developing breast cancer. If the test is positive, there is still a 15% to 20% chance of not developing breast cancer.

Genetic testing is costly, ranging from about $400 to more than $3,000, depending on the type of test. Insurance policies vary in providing coverage for genetic testing.

The results of genetic tests won't be available for several weeks. The length of time it takes to get results depends on the tests performed and under what circumstances they are done.

Genetic testing is highly controversial in society today. Legislation has been enacted to protect individuals who may have a documented genetic risk of developing cancer from employment and/or insurance problems. The best course of action a person can take is to become involved with an established genetic registry that can counsel individuals with a genetic risk for cancer.
