Hello, 3 weeks ago, I had a right upper lobe removed due to a cancer nodule found in a CT and PET scan. Dr says he got it all. Not in lymph nodes or spread anywhere else. He says no other treatment is needed. Should I get a second opinion? I haven't been told yet what kind of cancer it was. Follow up appointment is scheduled. What I do know is.........nodule did not grow in a 4 month time frame. My right lung has a small nodule in it that is not cancerous. Not sure what is next.......
