I had a spot on each of my lungs as well. My RO said they were probably just from radiation effects. I had a PET scan done and it confirmed that the spots were just scar tissue brought on from the radiation. I recently had a follow-up CT scan and the spots are now almost completely gone. Hopefully the spots that you have are just from radiation effects too.

Nine years out. New normal with limitations, but surviving and living life to the fullest.
