Had genetic testing, which was negative for BRCA-1 and -2. I did find out a lot of interesting information from the experience. For instance, a negative result is not a 100% assurance that you are, in fact, negative for the genes. The computers that run the tests are set to look for common defects, but there could be abnormalities or anomalies that the computer doesn't recognize, but which would be a positive result.
Also there are some genes, such as P-53, which there is no computerized test for, so they probably aren't going to test you for P-53 abnormalities unless you're in some type of study where a big pot of money is funding the research. And yet P-53 defects are known to be prevalent in families with adenocarcinomas.
Even though I test negative, I firmly believe that there is a genetic component to my cancer, and the genetics counselors all agreed that they didn't know which side of my family was more suspicious-looking on paper. They also agreed that, if there was anyone in the family they would want to test, it would be me.
So the testing really did nothing for me as far as decision-making. At the time of dx, I didn't want the testing done. I had two very young daughters who didn't need a positive genetic test darkening their futures. I chose to go through the testing many years later, when my brother was diagnosed with prostate cancer and both of my daughters, by that time, wanted to know if our family had one of "the genes."
Most of the information I got was beneficial to my girls, so it was worth it, in my estimation.
Hope I didn't just confuse you more!
Love and hugs...
