Large scale study shows cancers from ionising radiation
The association between radiation exposure and risk of second cancers was particularly significant for radiation-sensitive cancers, such as those of the lung, colon, breast, thyroid and bladder, as well as leukemia.
Study of Japanese atomic bomb survivors shows radiation exposure poses similar risk of first and second cancers, Health Canal.com, 17 Sept 10, First large-scale study to assess how radiation influences risk of multiple cancers
SEATTLE — It is well known that exposure to radiation has multiple harmful effects – including causing cancer – but until now, it has been unclear to what extent such exposure increases a person’s risk of developing more than one cancer.
The first large-scale study of the relationship between radiation dose and risk of multiple cancers among atomic bomb survivors in Hiroshima and Nagasaki, Japan reveals a similar risk in the development of first and second subsequent cancers.
Christopher I. Li, M.D., Ph.D., and colleagues at Fred Hutchinson Cancer Research Center led the study in collaboration with investigators at the Radiation Effects Research Foundation in Hiroshima and Nagasaki and the National Cancer Institute. The results appear in the Sept. 15 issue of Cancer Research.
We found that radiation exposure increased the risks of first and second cancers to a similar degree,” said first author Li, a breast cancer epidemiologist and member of the Public Health Sciences Division at the Hutchinson Center. “People exposed to radiation who developed cancer also had a high risk of developing a second cancer, and the risk was similar for both solid tumors and leukemias in both men and women, regardless of age at exposure or duration betweenfirst and second primary cancers,” he said. The association between radiation exposure and risk of second cancers was particularly significant for radiation-sensitive cancers, such as those of the lung, colon, breast, thyroid and bladder, as well as leukemia.
For the study, the researchers analyzed data from participants in the Life Span Study, a group of atomic bomb survivors in Hiroshima and Nagasaki who were followed from 1950, five years after the bombings, to 2002, the most recent year through which Hiroshima and Nagasaki cancer registry data were complete. The study followed 10,031 primary cancersurvivors, among whom 1,088 went on to develop second primary cancers.
Stomach, lung, liver and female breast cancers were the most commonly diagnosed first and second primary cancers….

Zoom webinar – “Nuclear Winter: The Environmental Consequences of a Nuclear Exchange.”
April 7th at 11:30 am PST / 2:30 pm EST
Nuclear Winter: The Environmental Consequences of a Nuclear Exchange”
Join us for an informative webinar with renowned atmospheric scientist, Professor Brian Toon, as he discusses the environmental risks and global impacts of a nuclear war. Despite the potential damage caused by the blast from even small nuclear weapons, many countries continue to invest in and expand nuclear arsenals. Professor Toon will provide a scientific assessment of civilian fatalities, agricultural failures, climate concerns, and complications with food supply that would follow any international nuclear conflict. We need to plan how to prevent nuclear conflict and avoid catastrophe. Politicians and military planners must be made aware of global climate and agricultural complications that would ensue. Don’t miss this opportunity to learn from, and engage in, this vital conversation
The Road to War brings a sharp focus to why it is not in Australia’s best interest to be dragged into a war with China which will almost inevitably go nuclear very quickly. The filmmaker has interviewed some of Australia’s senior foreign policy analysts who have vast experience behind them in analysing what really is going on here as the United States rattles its sabres with China. And sets us up to be its proxy, like the poor Ukranians have been fed into the Meatgrinder. So America can remain the Top Dog. The Road to War reveals how the United States through its spy base at Pine Gap and by stationing six nuclear capable B52 bombers in the Top End (without permission from the traditional owners) is making Australia a prime nuclear target if the current war of words suddenly melts down into full scale war.
The Road to War shows the implicit connection between Carbon emissions (the US military uses a whopping 70% of America’s annual petroleum to move its armies and vast War Machine around the globe to its 800+ military bases..but under a loophole wangled at Kyoto, the US military does not have to report its C02 annual emissions). The Road to War starts screening at selected cities and regional centres in March. See the trailer end for details.
