Hello @inderb, I'm glad that they found your adenocarcinoma early! Yay for no chemo and no radiation. You mentioned radon. Did you have your house tested? I also wonder if there was any biomarker testing completed on the tumor? It's not always completed for early-stage cancers. Many of us that don't seem to have risk factors but still develop lung cancer have developed one of the gene mutations that cause the cancer (EGFR, ALK, ROS1, etc).
