Meat, cancer and confusion

Does a new WHO report really say that bacon is bad a cigarettes? No, but poor communication of risk has resulted in a circus of confused media coverage.


This Monday the International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization, released their evaluation of the links between the consumption of red and processed meat, and cancer.

The group classified processed meats - such as bacon, sausages and cured meats - as carcinogenic to humans (Group 1), based on sufficient evidence in humans that the consumption of processed meat causes colorectal cancer.  They also classed the the consumption of red meat as probably carcinogenic to humans (Group 2A).
It is important note that the classification is an indication of how sure the experts are that a given thing causes cancer, but not how cancer-causing it is. In this case, processed meat was identified as contributing to cancer risk but it is not as carcinogenic as some other "Group 1" agents like tobacco and plutonium.
That distinction was lost in much of the international reporting with headlines such as 'Bacon as deadly as cigarettes and asbestos' splashed across news stories.

Cancer Research UK has provided a good summary of the classifications, placing the current IARC review in context.

University of Auckland Professor of Biostatistics Thomas Lumley told the SMC that many news reports had tried to link the risk of cancer from processed meat to the risk of cancer from other Group 1 carcinogens.
"There is no justification for this," he said. "IARC classifications are based only on the strength of evidence for an effect at some - not necessarily realistic - dose; they do not consider the size of effect.

“Group 1 carcinogens are those where IARC believes the cancer hazard is well-established, regardless of its strength. Group 1 includes asbestos, tobacco, and plutonium, but it also includes sunlight, oral contraceptives, and alcohol."

In one of the better pieces of reporting on the IARC announcement, science journalist Ed Yong expressed his frustration over the terrible communication of risk by the WHO, suggesting that IARC reports should be catergorised as 'confusogenic' to humans.
Following the whirlwind of reporting and misreporting over the week, the WHO issued a new statement today, offering some clearer and more practical advice:
"The latest IARC review does not ask people to stop eating processed meats but indicates that reducing consumption of these products can reduce the risk of colorectal cancer."

GM virus approved for cancer

In a New Zealand first, the Environmental Protection Authority has approved the use of a genetically modified virus for a liver cancer treatment trial.

The Pexa-Vec virus is the first genetically modified organism for a human therapeutic purpose that is capable of reproducing itself, to be approved by the Authority for release under the HSNO Act.

In a separate media release Environment Minister Dr Nick Smith, welcomed the approval.

“We should embrace new technologies like GM where there are clear benefits and where any risks to the environment can be effectively managed,” he said.

Dr James Ussher from the University of Otago told the SMC it is important that these cutting edge therapies are evaluated and, if demonstrated to be efficacious, made available in New Zealand.
“There are many investigational treatments and vaccines in the developmental pipeline that utilise genetic modification," he said.
"Many of these are showing promising results in pre-clinical and early clinical trials. These will undoubtedly become more common in the future.”

Meet the SMC's new advisors

A six person advisory board made up of senior journalists and scientists will help us identify and meet the changing needs of the media and the science sector.


The SMC Advisory Board has been appointed by the Royal Society of New Zealand to support and advise the Science Media Centre at a time of major change in the media landscape.
Long-time SMC advisor Dr Gavin Ellis, former editor in chief of the New Zealand Herald and a media lecturer at the University of Auckland, chairs the board.
Other board members include: Professor Michael Baker, public health physician and professor at the University of Otago, Wellington. Professor David Bibby, lecturer at Victoria University and former Dean of Science at the university. Alistair Dunn, Principal Scientist – Fisheries at NIWA. Renee Graham, Producer and reporter, TVNZ One News. Virginia Larson,  Editor, North & South, Bauer Media. SMC advisory board members are appointed for terms of two or three years and the board aims to formally meet two to three times year.
Visit the SMC website for more about our new board of advisors and on how the SMC operates.
