@junerose42 Update: I had biopsy of my lung nodule in August. The results were inconclusive - the technician couldn't get any tissue from the nodule, as its small and located in the mid lobe which makes it difficult to get. My pulmonologist recommended proceeding with treatment, either lung surgery to remove it along with part of my lung or CyberKnife radiation. I chose the latter as at age 83 I didn't want to undergo lung surgery. I had 3 CyberKnife treatments in September, on a Tuesday, Wednesday, and Thursday. I didn't feel anything during the treatments, but during the week after I felt fatigued. Since then, I feel fine. Radiation oncologist said I should schedule a CAT scan in January 2026 to see if the nodule is gone. I have that scheduled and will let you know the results. I'm grateful for the CyberKnife option, and just hope it worked!
