@363 Good news! I had the follow up scan in January after having the CyberKnife radiation on my lung nodule. The scan showed that the nodule had been reduced to scar tissue. I have another follow up scan to be done in July. I'll report the results here. The fact that mine was "spiculated" and had also grown some since first discovered in 2017 resulted in my decision to have the CyberKnife radiation treatment. Since deciding on radiation over surgery at age 83, I've attended a seminar with a lung surgeon at my local hospital whom I found very kind and impressive. He said that he did lung nodule surgeries on many patients in their 80s, and that they were up off the operating table and walking down the hall soon after their surgeries. He did the surgery with the Da Vinci Robot. Thus, I wouldn't rule out a surgical procedure if you choose that over radiation. But I hope you won't need either.
