I have had 2 robotic lung caner surgeries. I never had an oncologist. Both were stage 1A. One was an upper left lobectomy. One was an upper right wedge resection. I was having trouble getting my breath on Friday night. I went to Urgent Care after work. Had an xray. One thing led to another. CT, PET Scan, pulmonologist. Then Surgeon.
I am a former smoker for many years. I have been very lucky. My advice is to seek help right away. Don't wait! I know people present systems differently, but if you are having a hard time breathing, HELLO!
