my mom had cancer three times, the first time it was hodgkins stage 2 the second time it was hodgkins stage four in every bone in her body, the third time it was basil cell carsinoma(sorry if spelled wrong) this cancer was caused by the radiation that she had from the first time she had cancer. It is very hard when someone you love gets cancer, you never know when it will hit or how many times in their lifetime, all you can do is try to stay positive for them and be there when they need you. Lots of praying and hoping....
