In June of 2012 my Pop-pop was diagnosed with lung cancer. He was 62 years old. He had been very very tired, having to sit and catch his breath after just walking a block, sometimes even less. He also fell asleep at any given time, one time during dinner while still sitting at the table. My Mom urged him to go to the hospital after that. He was diagnosed with stage 4 (not sure which type) lung cancer and started chemo maybe 2 weeks later and after a few months was done treatment. He was then entered into rehab. The last time I saw him, though he was sleepy, he was able to hug and kiss everyone and I'm happy about that. Two days later my Mother was called because he didn't wake up, he was still alive but basically in a coma and died later that night. That was March, he barely made it a year. That was the most pain I have ever felt in my life. He stopped smoking 5 years before he was diagnosed.
