Diagnosed with NSCLC Adenocarcinoma at 50 and having never smoked I wanted to know why and how. So, after researching in earnest, I discovered the unfinished basement I played in for almost 11 years, was toxic. The radon I was breathing was 25X what is considered normal and safe. According to the EPA and NCINIH, RADON is the second leading cause of lung cancer. I want more people to know why their never smoker loved one died of Stage 4 lung cancer in less than a year. I suspect it is very possible, that person was exposed to radon.
