Nuclear fallout and lung cancer

"On the basis of data available from two representative samples of lung cancer deaths in the United States as well as national mortality statistics and other epidemiologic studies, the lung cancer mortality rate has risen substantially between 1914 and 1968 among persons who never smoked cigarettes. For white males the relative increase for ages 35--84 years has been about 15-fold; the relative increase for ages 65--84 years has been about 30-fold. For white females the relative increase for ages 35--84 years has been about seven fold. Most of the relative increase occurred before 1935 and was probably due to changes in diagnostic criteria. However, increases have continued up to the present for male nonsmokers, who now apparently have an annual age-adjusted lung cancer death rate of about 25 per 100,000 persons between the ages 35--84 years. The rising lung cancer rate among nonsmokers indicates that factors in addition to personal cigarette smoking have had a significant effect on the mortality rate from this disease. In spite of the limited quality of these data, they suggest that a more complete understanding of lung cancer etiology is needed."    Rising lung cancer mortality among nonsmokers. Enstrom JE.
The theory that the post world war rise in lung cancer was caused by rising cigarette consumption can not possibly explain the rise of lung cancer deaths in persons who have never smoked. However the period of nuclear fallout that occurred between 1945 and 1985 (UNSCEAR ANNEX C) can explain this as people would be exposed to inhaled radionuclides produced in atomic weapons testing regardless of their smoking status.

To test whether there is any correlation between the period of nuclear fallout and lung cancer rates , I have taken cancer data made available by the IARC and created charts to show the deaths that occurred during the period in question. Deaths that occurred during the nuclear fallout period are in red and deaths that occurred outside of this period are in black. If the global lung cancer epidemic was caused by nuclear weapons testing then we would expect to see a rise in lung cancers between 1945 and 1985 followed by a fall after 1985.

It is worth noting that in the USSR/Former Soviet Union smoking rates remained stable over the decades in question and yet the lung cancer signatures show a fall after atomic weapons testing fallout ends. If it were true that these epidemics were caused by smoking then this would be impossible.

It is worth noting that in Sweden smoking became popular decades after the USA and yet both lung cancer epidemics start when atomic testing starts and not after any theoretical time lag associated with the rise of cigarette use.

    A few remarks on the use of ASRs (Age-standardised rates):
    Japan is a highly developed country, with presently the highest life spans on record, and the use of ASR (W) pits it against the world population, including many countries with far lower life expectancies such as India and dozens of sub-saharan African countries, which are generally not included in the IARC database, and where most of the increase in world population occurred during the time-scales represented in the graphs. Consequently, the ASR graphs for developed countries like Japan, and the general ASR graph for 89 countries, are bound to reflect the effect of this adjustment more than any other factor.
    From the IARC database, here are the trends in lung cancer mortality in Japan from 1975 - a time when crude and standardised rates were similar - to 2013:

    Men: 19.66 (crude), 19.78 (ASR)
    Women: 7.19 (crude), 5.96 (ASR)
    Both sexes: 13.43 (crude), 12.87 (ASR)

    Men: 84.23 (crude), 27.19 (ASR)
    Women: 31.72 (crude), 7.80 (ASR)
    Both sexes: 57.98 (crude); 17.5 (ASR)

    China may be included, but if you check the relevant population pyramids, those 'selected areas' only total about 118 million people, less than 8.5% of the Chinese population, so the IARC figures for such a huge country are not very helpful. Moreover the criteria used to define 'rural' as opposed to 'urban' areas are not specified, and we can only speculate on how living conditions in rural China have changed over the last four decades.

    A final note on the averaging of the figures for both sexes: in addition to striking differences between national LC rates (evened out by the application of ASRs), and synchronical differences in male vs female rates, lung is the ONLY cancer site which shows not only divergent but sometimes *opposing* secular trends in female vs male rates, especially since the 1980s and the general decline in smoking prevalence, and I find that aspect of the problem mighty hard to reconcile with either the cigarette hypothesis or the fallout theory.

  2. I echo the reservations of Some French Bloke about sex averaging. It is one of my pet hates. Whilst I agree with him that the divergent and opposing trends in female vs male rates of lung cancer makes a nonsense of the cigarette hypothesis, I am less inclined to dismiss fallout just yet.

  3. The point about both sexes is well taken. I shall publish a chart showing male and female trends for the world when I get a chance.

  4. This comment has been removed by the author.

  5. I have added a chart showing male and female rates for the world. It is the second chart down from the top.

    Seems that the new chart illustrates the point in the last paragraph of my above comment rather well...
    Some additional observations on the power of age-standardised rates (ASRs) for propaganda purposes:
    The overall cancer death rate in Japan 2013 was 351.1/100,000, whittled down to a third (117.6/100,000) if ASR is applied. It even cuts their prostate cancer death rate for that year by over 74%: from 18.7/100,000 to 4.8/100,000! Quite handy if one is in the business of "proving" that the use of the prostate specific antigen test from the 1980s onwards has had a positive impact on mortality, even though the prostate cancer death rate for Japan in 1984 was at 3.95/100,000 (3.15 ASR). If the crude figures are too embarrassing to mention, just posit that the moderate increase would have been far greater "due to an ageing population"! The Mainstream Media routinely use those adjusted figures (sometimes not even specified in the small print) to make their point, in the assurance that only a minute fraction of the general public will bother to check and reevaluate the various 'findings' and advice presented in the article.
    These two graphs show how ASRs can serve not only to artificially lower mortality levels, but also to reverse a trend:

  7. Rather annoyingly blogspot won't embed images in posts which would show the difference between crude and ASR rates for Japan (which is very striking).

    I have added the crude rates for male and females for the world (third chart down) which also illustrates the point by comparing it with the ASR chart above it. It is worth noting that not all the data for all countries will be up to date so the trends for the last five years are so will probably not look like that in a few years time.
