I am so sorry to hear about your mom. There are some things to ask when you see the DR.
What type of lung cancer. What stage. What treatments, chemo (what types), radiation, surgery?
Make sure the Dr gives her prescriptions for anti nausea meds, compazine, zofran etc. She may need these if she is on chemo.
Many of us here on these boards have survived cancer MUCH longer than the 'odds'. There is always hope. Please come back and update us on what is up.
Love Cindy
