Gene testing - The confusion of knowing what result I wish for

Since 2006 I've had most of my disposable bits removed. A recurrence after n 2016 meant some non disposable things, like my axillary lymph nodes, went too. 
My logic may be completely screwed up, but I don't give a hoot about the gene test from my own perspective as I know my disease is aggressive and rerstant to the treatment ive had,. Why I have it is irrelevant, and even if I am gene susceptible, everyone I'm related to still needs to do their own tests.
