The Industrial Injuries Advisory Council recommended that asbestos-related lung cancer should for the first time be recognised as a prescribed industrial disease where there is not also asbestosis. The recommendation was accepted by government.

A 1982 study conducted by the Institute of Occupational Medicine in Edinburgh found a clear link between some jobs in the British steel and coke industries and lung cancer. The authors noted that the elevated rates of lung cancer in blast furnace men “should be investigated”. [A 1990 study by IOM, part financed by British Steel, found for these workers there was “about a twofold risk of lung cancer relative to steel workers in other occupations.” The study design meant many cancers and other chronic diseases would not have yet emerged at the conclusion of the study.] For coke oven workers, they concluded “we consider than occupationally related excess of lung cancer has been shown clearly. We consider that the excess number of lung cancer deaths among younger workers may reflect the real risks more accurately than the results for all men.”  In 1986, the UK Industrial Injuries Advisory Council considered whether lung cancer in coke oven workers should be added to the list of prescribed industrial diseases for which no-fault state compensation was payable. IIAC said no. After another quarter of a century of uncompensated deaths, only in 2011 did IIAC conclude “that lung cancer associated with (i) at least five years in total of work at the top of a coke oven or (ii) at least 15 years in total of coke oven work, should be added to the list of prescribed diseases. For workers who move between these coke oven jobs, and whose employment in top oven work amounts to less than five years in total, we recommend that each year of top oven work be counted as contributing three years towards the greater target of 15 years, as set out in further detail in our report.” That same year IIAC declined to add lung cancer in foundry workers to the prescribed disease list.

The 1981 Doll/Peto paper remained the UK Health and Safety Executive’s preferred source for estimates of occupational cancer causes and incidence until 2008, long after the findings has been disputed and described as “discredited”.  Errors in methodology led to a substantial under-estimate of the true incidence. The pro-industry leanings of the lead author was also criticised. Hazards magazine noted in 2007 that basing official policies on Doll/Peto estimates has resulted in a chronic failure to secure either the resources or the priority required for meaningful preventive action.

The major challengers of the estimates made by Doll and Peto from the late 1970s and 1980s. Epstein and Schwartz give greater weight to toxicological and clinical research and challenge the relatively low estimates given by Doll and Peto to work and wider environmental factors. Self-interest of the chemical industry apart, the lifestyle theory of cancer causation is held to reflect misinformation and ‘inactive conservatism’.

This groundbreaking guide from the US autoworkers’ union UAW, issued in 1980 [editor’s note: reprinted in 1992], gave workers the information to interpret epidemiological studies for themselves, identify their strengths and weaknesses and to identify work-related cancer risks for themselves.

The initiative came as the UAW leadership declared “war on workplace cancer” in response to an alarming series of cancer mortality studies conducted among autoworkers by government, company, and union epidemiologists.

These studies revealed an “increased proportion of cancer deaths” among “workers in machining operations, foundry workers, and workers in vehicle assembly plants”; the epidemiologists believed those deaths were related to occupational carcinogen exposure.

Two major US reports published shortly before the 1981 Doll/Peto report – one from US government organisations  and another backed by employers’ organisations – put the occupational cancer contribution at least 20 per cent of all cancers, with the industry-backed report conceding occupational cancer constituted “a public health catastrophe”.

The study uncovered high rates of leukaemias in a population exposed only to the solvent benzene and where benzene levels were generally below recommended limits. The authors acknowledge that the figures underestimate the scale of the problem. It was  the first cohort study of workers linking benzene exposure directly to leukaemia. Under-reporting remains a problem to the present. The industry was criticised in 2014 after it was revealed it has operated a long-term project to suppress or rebut evidence of this cancer link (see CPI, 2014). A 2004 study confirmed health risks at low level exposure to benzene. Concerns were raised in 2014 about harmful benzene exposure levels in the vicinity of fracking operations (see Macey and others, 2014).
