In cases in which a family has a history of breast and/or ovarian cancer and no known mutation in BRCA1 or BRCA2 has been previously identified, a negative test result is not informative. It is not possible to tell whether an individual has a harmful BRCA1 or BRCA2 mutation that was not detected by testing (a “false negative”) or whether the result is a true negative. In addition, it is possible for people to have a mutation in a gene other than BRCA1 or BRCA2 that increases their cancer risk but is not detectable by the test(s) used. - from www.cancer.govThe whole point of this test is to determine your risk level as accurately as possible so that you can take the correct preventive measures. I don't want to get to cancer! I am 18 months away from the beginning of my family history with breast cancer. I want to stop it by any means necessary and if I have the opportunity to do so, I will. Maybe that sounds severe or exaggerated but I wouldn't play Russian Roulette with a gun 1/3 filled either!
I know I could skip the test and continue routine surveillance, but that doesn't sound right for me (although I foresee a lifetime of it anyways). A new doctor appointment every 3 months for the rest of my life spent waiting to hear: You have breast cancer. No thanks! I don't want to detect it early, I don't want to get it and survive, I don't want treatment, chemo, radiation, I don't want cancer period. I want to go back to the day that I only needed an annual mammogram.
And as much as I don't want to wish BRCA on anyone, let alone myself, knowing I'll never be a true negative makes me want to be a positive. I have an actual answer then, I have real numbers to work with, real risks, real outcomes, not hypotecticals based on a high risk.
