Lisa,
Welcome from a fellow Lisa and daughter who's mom has lung cancer. I know how scary this all is. It seems that it's easy for us to say take it one day at a time, but honestly that's all we can do. As Ned said, be sure some one goes along to the appt and takes notes - I have found this so helpful. I also keep a calendar of my mom's appointments and some times how she's feeling if it's out of the ordinary. Take a deep breath. Know we are all here for you. Let us know how tomorrow goes.
Hugs and prayers,
Lisa
P.S. Happy Birthday tomorrow.
