Lung cancer in non-smokers on the rise

Researchers report increasing numbers of non-smokers contracting lung cancer : Tobacco Reporter

There has been an increase in the number of non-smokers being diagnosed with non-small cell lung cancer inFrance, according to a story in News-Medical.net quoting a report by researchers at theFrenchCollegeof General Hospital Respiratory Physicians.

Little is known about risk factors that can cause lung cancer in non-smokers, though the World Health Organization (WHO) confirmed earlier this year that exhaust fumes from diesel engines were a cause of the disease.

If diesel engines are indeed a cause of lung cancer in non-smokers, isn't safe to assume that these same fumes harbor the potential to cause lung cancer in at least some smokers as well?

  1. It's a pity that they do not give a link to the actual study, J. In my experience of reading these studies (or in many cases, trying to read the studies!), there is often a big difference between what the study actually shows asd what the abstract/press release says. For example, the article that you link to does not say how big the increase is, which is unusual even in a newspaper/magazine article. In view of the increase in life expectancy, is the increase in LC age related? There are so many questions...

  2. "In view of the increase in life expectancy, is the increase in LC age related?"

    Well, one thing is for certain Junican: It's not related to tobacco in any shape or form.

  3. Here's a little something else that you may find interesting:

    "NEARLY 80% OF NEW LUNG CANCER CASES ARE FORMER AND NEVER SMOKERS"

  4. Interesting...... I wonder if the researchers standardised for the reduction in smoking and the numerous other confounders, like age? If they did not, then they are statisticians out of work. If they did, then it suggests that there is much more to lung cancer incidence than smoking.

  5. I would imagine that all factors were taken into account, but who am I to say for sure:-) A couple of things stand out as being obvious though:

    1) Many former smokers are still contracting the disease, even after quitting decades ago.

    2) Life expectancy rates in much of the Western world have remained mostly stagnant (according to what I've read) for the last few decades.
