I went through this in 2015!!! It's not fun. I caught it at stage 1 only because I could see it and jumped right on it. 7 1/2 weeks of radiation!!! Then this past February 26th, had major lung surgery on my right lung. Thank God I had a bad fall in January or I wouldn't have known it. They almost lost me twice 2 days later. I didn't know it because it was very early in the morning and I was sleeping. My heart rate went real low. I have an air leak in lung, which is pretty rare and my Doctor can't figure it out. Don't know what will happen next. He was able to get the cancer out with surgery.
