Several years ago, one of my dad's brothers told us that he had a genetic marker that increased the likelihood that he'd develop colon cancer (which he already had) as well as several other cancers. His doctor suggested that his siblings get tested for this genetic marker, and if any of them had it, that their kids also be tested. Since my dad had already had colon cancer three times, it was assumed that he had the genetic marker, and my siblings and I had to decide whether or not to get tested.
There are two thoughts on genetic testing. One side believes that knowledge is power and by knowing, you can take steps to prevent illness or catch it early. The other side believes ignorance is bliss and by not knowing, you can enjoy life and let whatever is going to happen, happen. (The two sides are much more complicated than this, of course, but this is the easy simplification.)
I decided to have the test done. I have the genetic marker that significantly increases my risk for colon cancer. So, I've been getting an annual colonoscopy since I was 31. Not exactly my favorite annual event, but I'd rather do that than develop late stage colon cancer, when it is often too late to treat successfully. This genetic marker also increases my risk for developing some other cancers, including ovarian, uterine, endometrial, and stomach. Again, knowing these risks allows me to be proactive with screening.
What do you think about genetic testing? Is it a good idea? Would you want to know if you're predisposed to developing a disease?

Amy, your Mom and Dad are especially proud of you...first, for choosing to be proactive with testing, and second, to challenge others to do the same, or at least to think about the topic! Your "glass, half-full" attitude gives a happy outlook and inspires those with whom you come in contact! Thanks, ABC(F) kid!
