My husband went to the doctor for his knee pain, I stayed at home because it was not a big deal. 3 hours went by and I am beginning to worry. It wasn't long I heard him pull up. He has the oddest look on his face he looks at me and says I have stage 3 lung cancer. I didn't believe him at first, then I realized he was serious, my world ended right then and there, I've been in a state of shock ever since.
