Now that the Human Genome Project has provided the world with the ability to test their genetic code and determine whether or not there is anything they should be concerned about lurking in their future, the obvious question is this; “should I get genetic testing?” On the one hand, genetic testing can be the window into the future and could help save or greatly prolong your life. On the other hand, the tests are not always accurate, and the results are not always good news. There are many factors to consider when contemplating a genetic test.
For certain diseases such as colon cancer, early detection can be the difference between a full recovery and death. This disease also has a very strong genetic link, meaning if your parents or grandparents had it, there is a good chance you could have it, particularly in men. In this instance, genetic testing may be incredibly beneficial, as locating and identifying the gene means doctors can take a closer look and keep a watchful eye for even the slightest symptom. In situation where the genetics are strong and early detection is key, genetic testing is a good idea.
However not all diseases are as treatable with early detection as colon cancer. One such disease that has similarly strong genetic links is Alzheimer’s disease. Alzheimer’s can be identified just as easily on a genetics test, but unfortunately can not be cured. In situations like this, having a genetics test performed could potentially do more harm than good. Discovering that there is a significantly large chance that you could develop a life altering, debilitating and ultimately fatal disease, with nothing to do but wait for it to arrive, can be incredibly damaging. For that reason, genetics tests are not appropriate in every situation.
Although having a genetics test performed can be of great assistance to some, it can be a great hindrance to others. The decision to have a genetics test performed rest solely on whether or not you truly want to know the answers.
