That;s a question I suspect not just you and I, but a whole bunch of other women would like an answer to. You can spin your head thinking that you got it because of this or that, but truth is it could be ANYTHING!
Cancer doesn't run in my family and I got it in 2005, and after a sucessful treatment I have been diagnosed 3 years later that recurrent breast cancer. I have surgery next week and then radiation & chemo to follow. I quit asking why me, cause there is no answer - if there where then there would be a cure.
Good luck to you. Be strong!
