C..
I guess I feel about this the same way that I feel about IQ testing.
I know, I know.... it seems like a leap. But really, it's not.
once you have the info.... what are you going to do with it? You can have a high IQ and be "dumb". You can have a low IQ and be a CEO. It's not about the test result.
A positive result for the BRCA test is seen in about 5% of the breast cancers and 10% of the ovarian cancers in all women.
A positive test tells only tells you that you have a significantly higher than average chance of developing breast cancer. But based on your history.... don't you know that already?
Also a negative result doesn't put you in the clear. At all. In fact, if your family members all test negative you can STILL get breast cancer - which you already know. the gene mutation is there in only FIVE percent of all woman who get breast cancer. So, out of the 211,731 people in 2009 (based on CDC statistics) who were diagnosed with breast cancer..... over 200,000 of them did NOT have the mutation (based on the 5% rule).
I also want to reiterate that testing positive for the BRCA gene doesn't really tell you anything other than you have a higher chance than average of getting breast or ovarian cancer.... not that you WILL get cancer. So, I go back to what will you do with that information? How will it help you?
- Will you do better monthly exams? Why not do that anyway....
- Will you for sure get a mammogram screening? Why not do that anyway?
- Will you have anxiety just "waiting for the shoe to drop" if you test positive? Why put yourself through that.
- Will you relax if your test is negative? You shouldn't..... because a negative result doesn't mean you won't get breast cancer. You must be just as diligent with early detection measures.
Having said all that.... I would get the test. I think all the data they can get will enable them to analyze and predict which will be beneficial in the future. But I don't know that *I* would personally USE the information for anything. If you know what I mean.
Good Luck with your decision.
