In 2018 at my yearly visit to my doctor it was suggested to me that I get a chest X-ray since I had been a smoker for a long time. Normally I would have said no thank you, but for some reason I agreed. To my surprise they found it had non-small cell lung cancer. It Was found early, THANK GOD. I had it removed without having to have any further treatment. I urge everyone that has been a smoker to get a X-ray. It could save your life. It saved mine.
