Hi there. As my mom used to say "never put the cart before the horse" or in otherwise do not worry until there is something to worry about.
I know you are scared but try and think positive thoughts because in the end it may not be cancer afterall but something much more pleasant and easy to treat.
Hang in there and bless you,
Barbara~
