The good news is that the MRI brain scan came out neg - no tumors.
I actually was all set to go - my head mold was made and the tattoos were put on my chest to make sure we were all lined up. As the Doc was running a test run, he noticed the collapsed lung and all bets were off. All in all, good news since both cancers are seperate and treatable. And for the FIRST time, the Doc mentioned the tumors were curable !!!
