It’s absolutely normal to feel the way you do, cancer is scary and the fear of it is real, I had a lobectomy on my upper left lobe, stage 1A2, surgery was successful and no further treatment was needed. I worried endlessly about it coming back and almost 2 years later it did so they removed a wedge from the lower right lobe with no further treatment. The best thing we have is early detection and this makes a huge difference for better results, I see that you had early diagnosis too. I know it’s difficult to go through the scans always worrying if they will find something, the best we have is that it was caught early, I find that it helps me to keep this in mind, not knowing is far more scarier, best wishes for good results.
