These numbers look serious but according to the Canadian Cancer society there were 10,600 cases of lung cancer in Ontario over the previous year. Workplace related lung cancers come in at less than 10%.

Studies like this one unintentionally misrepresent the importance of issues. Eradicating workplace hazards is a good thing but there comes a point where further specific preventive measures do not yield significant benefits. 

One can sympathize with the victims of workplace cancers but 1 in 2 Canadians will sometime in their lives develop cancer. 1 in 4 will die from it. Focus should be elsewhere than the workplace.

If we really wanted to prevent cancers we should ban a variety of chemicals in foods, including sugar. Diet is the key to controlling disease.
