I had my appointment today. The genetics oncologist was really helpful and went through my family tree (which was rather challenging as my cousins' grandchildren are older than me and there are so many knowledge gaps). In her opinion, it is more likely than not, that there is a hereditary factor with my only sibling having bc at 32. I qualify for the free genetic Braova test and will go ahead with that, although it is quite possible that it may come out negative. From there, depending on the results, we will have further discussions regarding further direction which may include decisions about taking the other breast and possibly ovaries. It also has implications for my kids and nephews as to when they start getting screened.
Thanks for you help, everyone.
