Genetic Testing

I was referred to a genetic specialist and had to fill in an extensive history of siblings, parents and their history. It took some time as I am 1 of 10. My Dad was 1 of 9....and many many people gene positive. The idea of the pre counselling is discussing risks beforehand... otherwise getting the result is like being hit with a cancer diagnosis. My family had a known positive gene...but they were in Scotland so the team were able to contact them beforehand so they knew where on the gene it was faulty. By doing the tree also means as further positive people turn up we have a clearer picture if it is a genetic bc.
I believe they often do offer very young tnbc ladies testing. The thing is ...it is more tban just brac1 and 2 that cause bc. It can be from at least another 3 other gene mutations. That's why best handled by the experts. They also connect  you with appropriate people if needed if positive. Like a onco-gynacologist. I had already made the decision for further surgery if I was positive. However as I wasn't, it wasn't necessary. Some faulty genes only cause bc but not ovarian...which is helpful information to know.  My siblings with yhe same father were all tested to see if we carried the faulty Scottish gene. Fortunately none of us did...which was a huge relief.
