Genetic Testing

Genetic testing is a way for medical providers to detect certain mutations inside your genes that could increase your risk of cancer.

Genes are what determine all of your physical traits — hair color, eye color, height, etc. You inherit your genes from your biological parents.

Mutations — or changes — in your genes can lead to the uncontrolled growth of cells that cause cancer.

It may also be advised if you have or previously had cancer to determine your risk for developing other cancers in the future. This also may help other family members decide if they, too, would like predictive genetic testing.

Predictive genetic testing can be arranged through your physician.

Genetic testing if you have cancer

If you have cancer, genetic testing can also be valuable.

Along with helping determine your risk of developing other cancers, genetic testing can help inform your treatment. Researchers are increasingly discovering links between certain genetic mutations and the effectiveness of different treatments. Knowing about certain genetic mutations may guide your cancer care specialist on what types of chemotherapy or immunotherapy they recommend, for instance.
