You may ask me where my tinfoil hat is, but something strange seems to be happening. My neighbour who never smoked suddenly discovered he has terminal lung cancer. Radon tests in his house were negative. The cases of early lung cancer in healthy non-smoking individuals seem to be on rise in Ireland over last 5-6 years according to the official statistics. In the news I'm reading about massive amount of cases of persistent cough which "takes weeks to resolve".
