- copperx 7y agoIt still is. If you live at sea level, your chances of getting lung cancer are much higher that of you live at higher elevations.
- quotemstr 7y agoHuh. I didn't know that. What's the altitude at which cancer risk starts increasing again due to radiation exposure?
- nitrogen 7y agoInteresting; could that be caused by most cities being near sea level and most people living near cities, and thus pollution rather than oxygen might be the root cause?
- copperx 7y agoI don't have a link to the study, but the researchers of the study I read were very meticulous and did discard all other obvious explanations before concluding that altitude was the best explanation.
