Lung cancer continues to be the leading cause of cancer deaths.
While we know that cigarette smoking causes lung cancer, many physicians are not aware of the hidden threat posed by naturally occurring radon gas. The World Health Organization and the National Academy of Sciences agree that radon is a known human carcinogen. 3 Radon gas is a byproduct of naturally occurring uranium decay. Odorless, tasteless and invisible, it seeps into homes through cracks in foundations, pores in walls, floor drains or any areas exposed to the ground. Differences in pressure create a vacuum effect between buildings and the ground that draws radon into homes, where it can accumulate undiluted by outdoor air.
