What is genetic testing and how might it be helpful?
Genetic testing looks for mutations within specific genes. Having a gene mutation indicates that a person is at increased risk of developing a particular type of cancer. For individuals who have had cancer, this test result may indicate an increased risk for another cancer. Having a gene mutation does not mean a 100% chance that cancer will develop. Genetic testing can be helpful in guiding the medical management decisions patients and their family members choose to make. For instance, carriers of a particular gene may choose to have more aggressive screening tests done on a regular basis. Or, they may consider other options that may lower the risk of cancer. It may also provide cancer risk information to family members.
