Genetic testing has come a long way; you can ask your doctor for a genetic test, or order a direct-to-consumer test. Maybe someone in your family has Alzheimer' s, breast cancer, cystic fibrosis or another genetic disorder. You're thinking about getting tested for the genetic factors that scientists have identified as raising a person's chances of developing the disease later in life. Does it matter if there is a cure or no cure or real treatment for the disease at the present time? Is it covered by medical insurance? What are the costs? Do you have to worry about your health insurance getting access to your results? Would knowing the answer be a huge relief or a giant headache? Would you do it? Research genetic testing and give us your opinion.
