Genetic testing can be an important part of cancer care. Most cancer is caused by aging and environment. About 10% (1 in 10) of cancer has an inherited risk factor passed down from a parent. It is important to find out if you have an inherited risk factor, because it could change your medical care.
What does genetic testing tell us?
Genetic testing does not diagnose cancer. Genetic testing can give us information for:
- Improving the treatment plan for some cancers either now or in the future.
- Monitoring or preventing other types of cancer for you.
- Monitoring or preventing cancer for you family members.
How is testing done?
Testing is done on a saliva or blood sample. Results are available in about two to four weeks. You will have an appointment with a Genetic Counselor before and/or after testing to learn more about genetic testing and how it affects you and your family.
Types of Results
Your genetic counselor will look at both the test results and your personal and family history to personalize cancer screening and preventions strategies.
| Positive +
|
You have a genetic risk factor for cancer. This information can help with treating your cancer or preventing future cancers. A positive result is also important for family members. |
| Negative - |
The test did not find a genetic risk factor for cancer. |
| Uncertain ? |
Your test did not find any risk factors for cancer, but more research is need to understand all the results. You do not need to change your medical care based on this result. |
