Cancer seems all too common in your family, but should you have a genetic test to learn more about your risk?

Genetic tests offer a glimpse of what the future may hold for your health. But the look has limitations. Genetic tests can't tell you with certainly whether you'll develop a disease or how severe it might be if you do develop it. They can only tell you if you have a mutation that is shown to be associated with a risk of the disease.

Deciding to have genetic testing is complicated. That's why it's often recommended you consult with a genetic counselor.

The March issue of Mayo Clinic Women's HealthSource offers ways a genetic counselor can help:

*Research your family history and medical records to assess your risk of a genetic disorder or the likelihood that you carry a genetic mutation.

* Provide information on the benefits, risks and limitations of a specific genetic test.

* Explain the implications of a positive, negative or indeterminate test result, for both you and your family.

* Consider possible treatment options or preventive measures if a gene mutation is found.

* Costs for genetic tests can range from less than $100 to several thousand dollars. These tests may not be covered by insurance. Fortunately, many states have enacted laws that prohibit using genetic test information to determine eligibility for health insurance.
