One other thing, I'm sorry to hear about your dad, I'll keep you both in my prayers. I know what your going thru as my mom was diagnosed with FAP (colon cancer) 2 years ago. Since then my grandma, aunt, and brother have all been diagnosed with the same. And I've just recently lost 2 grandparents to cancer. I myself have been tested but so far so good, there IS hope!! If you ever need anything don't hesitate to write!
