Hi Cindylb. I remember when my husband was being diagnosed, what a meandering path it was. They thought it was his heart, then acid reflux, then emphysema. The better part of a year later after many many tests and diagnostic surgeries, we found it was indeed lung cancer. Now 18 months after that point he is cancer free and slowly gaining strength. It is a wretched thing to go through and I'm pulling for you! Be strong! I kept telling myself, "I can eat this elephant, one bite at a time!"
