"You have inherited your eye and hair color, nose, facial features, and other physical characteristics from your parents and their ancestors. You may have also inherited an increased risk of developing certain cancers and other diseases. Genetic testing can be used by some people to better understand their risk of developing certain cancers.
Based on your personal history and your family's history of cancer, genetic testing may be recommended by your oncologist or a family member"s doctor. Before genetic testing is done, you may meet with a genetic counselor. Genetic counselors are healthcare professionals who help identify patterns that exist within a family as well as assess other factors that are known to be related to hereditary cancers.
During an appointment with the genetic counselor, you will be asked a lot of questions about your history and your family's medical history. Based on what you share, genetic testing may be recommended. The tests will look for inherited genetic mutations that put you or your family members who also have the mutation at a higher risk of developing certain cancers."
