Let s take a closer look at the arguments from both sides. The proponents are up first. These individuals believe that persons from high risk families can gain many benefits from knowing whether or not they carry a genetic mutation. For instance, a negative test that is strongly predictive can reassure a person and provide relief. A negative test can also eliminate the need for continued checkups and tests, like a colonoscopy, which is routine for individuals from high risk families.
Proponents also point to a number of benefits from positive test result.
If the test indicates that a person will definitely develop a disease, the person can begin to prepare for that time. Under the best circumstances, a positive test result can lead to counseling and intervention to help reduce the risk of developing that disease. For example, the earlier that colon cancer is detected, the greater the chance of survival. Opponents to predictive genetic testing point out many problems that have already resulted or may result from these tests. For one, they argue that uncertainty is not really relieved by these tests because they do no indicate whether or not the person will develop the disease, and the time frame that the disease could occur.
