If you don't mind, because I think this is fruitful point about getting genetic testing. The challenge is that genetic testing always works best if someone in your family who has had the cancer is the first one to get genetic testing. Actually, across Canada, which would be a whole other discussion for us, there is a varied landscape of how easy or how hard it is to access that testing, and provincial guidelines do not agree.
When you haven't had cancer and you opt for a genetic test, then there is some nuance to it, because if you come back with a gene, that's helpful. However, if you come back without a gene it doesn't tell us whether your family is carrying a gene and you didn't get it so that you're actually relatively low or population risk, or whether there is something else going on in your family—all the mix of small genes that we can't measure, lifestyle choices, our environment—that goes into your risk and you are still at elevated risk for breast cancer.
Testing people who haven't had cancer comes with difficulty, and that's where our medical genetics colleagues are really important in that, and I do think it probably.... I'll stop now because it's a bit different.
