Now take a deep breath! You have just inhaled roughly that many molecules! Quite mind-boggling, but if you want a statistic that may leave you breathless, the single breath you just took contained at least one molecule that had once been exhaled by Napoleon, Einstein, Genghis Khan, or anyone else in history you care, or don’t care to choose. Most of those molecules are either nitrogen or oxygen but there are plenty of others, many of which would be classified as pollutants.</p> Thu, 08 Feb 2024 01:50:58 +0000 Joe Schwarcz PhD 9825 at /oss /oss/article/medical-critical-thinking/what-about-screening-lung-cancer <hr /> <p><em>This article was originally posted in the</em> <a href="https://montrealgazette.com/opinion/columnists/christopher-labos-what-about-screening-for-lung-cancer"><em>Montreal Gazette.</em></a></p> Fri, 10 Nov 2023 14:39:49 +0000 Christopher Labos MD, MSc 9716 at /oss /oss/article/health-and-nutrition/non-smokers-lung-cancer-and-hidden-link <p>The link between cigarette smoking and lung cancer is widely acknowledged. But not everyone who smokes gets lung cancer and not everyone who gets lung cancer is a smoker. How does one contract the so-called non-smoker’s lung cancer? The answer, one might say, is blowing in the wind. And that wind may be blowing a gas called radon.     </p> Fri, 31 Dec 2021 19:08:52 +0000 Nancy Liu-Sullivan, PhD 8970 at /oss /oss/article/health/lung-cancer-screening-can-save-lives <p> </p> <hr /> <p><em>This article was first published in</em><span> </span><a href="https://montrealgazette.com/opinion/columnists/christopher-labos-lung-cancer-screening-can-save-lives">The Montreal Gazette<span>.</span></a></p> Tue, 10 Mar 2020 18:51:26 +0000 Christopher Labos MD, MSc 8169 at /oss
