Debbie, we can all agree with that, but it's my understanding that this test worries some health providers. It ONLY tests BRCA1 and BRCA2, and there are quite a few other genes and factors that are just as important. As I understand it, after listening to a talk by a scientist/researcher on this, many women with the worst BRCA test results never get breast cancer, and others with the best results do get breast cancer. All this test reveals is what your BRCA1 and BRCA2 reveals, not what your real cancer risk is.
The fear is that some will wrongly interpret the results, as in "my results are terrible, might as well cut them off", or the opposite "my results are great, never have to do a breast exam again". Both are completely wrong. Everyone with a breast has a breast cancer risk, women have a higher risk. Bad BRCA1 and BRCA2 variants are just one factor, and shouldn't be over-hyped. It's hard not to think 23 and Me found a market opportunity, playing on natural fears.
