Please do yourself a big favor and have your lungs x-rayed every 3 to 5 years. Renal cancer can, and does, shed as it grows and the cysts just sit there, waiting. A friend of mine who had a kidney removed (cancer) about 7 years ago is undergoing immunotherapy for the cysts that have occurred in her lungs (never smoked). A biopsy showed that they were renal cancer, despite being in the lungs. So, keep checking,
And good on you,
