I read your comment about coughing and you mentioned that you have smoked for 52 years, my question is did you quit smoking before getting cancer or were you done with smoking long before the cancer diagnosis? I was a cigarette smoker for 43 years and I finally quit, the cancer showed up 8 years later. I had a upper left lobectomy and 2 years later I had a partial lobectomy for another cancer in the lower right lung. I believe that if you recently stopped smoking before the cancer you would probably have a cough because it’s a common symptom for quitting smoking, your lungs are cleaning up the tar and nicotine in cigarettes, it’s actually a good thing and normal for ex smokers. I would mention it to the doctor if you feel it needs further investigation. I wish you good luck with your recovery and enjoy the beautiful things that life has to offer you.
