The following disadvantages exist for genetic testing:
Even if you test positive for an abnormal gene, there is no proven way to eliminate cancer risk.
There is no guarantee that test results will remain private.
You may face discrimination for health insurance, life insurance, or employment.
Emotional distress. You may find it harder to cope with your cancer risk after you know your test results. The results may also have a significant emotional impact on your family and friends.
Negative test results may provide a false sense of security, because you may think you have no chance of getting breast cancer, which is not true.
