In 1994, a Time/CNN poll asked people whether they would take a genetic test that could tell them what diseases they were likely to suffer later in life. Nearly as many people said they would prefer to remain ignorant (49 percent) as said they would like to know (50 percent). The decision to undergo testing is a very personal one. It should also be voluntary. A person should agree to the test only if he or she desires the information. No one considering a gene test should be pressured into it by relatives, health care providers, or anyone else.
