Hi @Spillsy, I had genetic testing done really to help me decide if I was going to have mastectomies or not. I had them done anyway even tho no BRCA.
I was triple negative like @onemargie, and because TNBC has higher chance of BRCA mutation it's usually recommended. I had a 'color test' I saw a geneticist and then sent my saliva to the USA and it tested for about 30 gene mutations. This was a good option for me as I had melanoma a couple of years ago. It's expensive - $550 for the doctor and $450 for the test. But the Foundation at my place of treatment helped me out with some of the payment.
I think testing is smart to help you choose treatment path. ie mastectomies or not. Every little bit of info helps.
Once you you have the test tho, if positive may have implications for your children's ability to apply for life insurance down the track if you are positive. My poor teenage son was quite anxious about the results bless him. Xx
