Hi I'm sorry your wife was diagnosed with lung cancer, but it seems like it was caught somewhat early, so that is encouraging. I had two lung surgeries and still have a couple of concerning nodules in my right lung and a third surgery doesn't look likely so I am also looking into radiation treatments. I'm exploring the three modalities you mentioned. My nodule is near my breathing tube, so I am leaning towards proton therapy if I am a candidate as it is supposed to be gentler onthe surrounding areas. I hope others who had radiation treatments join in on this discussion with their experiences. In the meantime, I'm attaching a couple of links below that I hope helps. Please feel free to follow up with us, we are here for you both, to share and support one another. Warmly, Alisa, Lung Cancer Team Patient Leader
