The literature indicates that the strongest concerns for women with early-stage breast cancer are those relating directly to cancer as a health and life threat, the most salient being the possibility of recurrence (Spencer et al., 1999). The experience of breast cancer often forces women to confront fear and uncertainty, and most overwhelming, the idea of their own mortality. These issues bring up many existential questions, for example “What is important in my life?” and “What meaning does my life have?”. | International Agency for Research on Cancer World Health Organization PRESS RELEASE N 213 12 June 2012 IARC DIESEL ENGINE EXHAUST CARCINOGENIC Lyon France June 12 2012 After a week-long meeting of international experts the International Agency for Research on Cancer IARC which is part of the World Health Organization WHO today classified diesel engine exhaust as carcinogenic to humans Group 1 based on sufficient evidence that exposure is associated with an increased risk for lung cancer. Background In 1988 IARC classified diesel exhaust as probably carcinogenic to humans Group 2A . An Advisory Group which reviews and recommends future priorities for the IARC Monographs Program had recommended diesel exhaust as a high priority for re-evaluation since 1998. There has been mounting concern about the cancer-causing potential of diesel exhaust particularly based on findings in epidemiological studies of workers exposed in various settings. This was re-emphasized by the publication in March 2012 of the results of a large US National Cancer Institute National Institute for Occupational Safety and Health study of occupational exposure to such emissions in underground miners which showed an increased risk of death from lung cancer in exposed workers 1 . Evaluation The scientific evidence was reviewed thoroughly by the Working Group and overall it was concluded that there was sufficient evidence in humans for the carcinogenicity of diesel exhaust. The Working Group found that diesel exhaust is a cause of lung cancer sufficient evidence and also noted a positive association limited evidence with an increased risk of bladder cancer Group 1 . The Working Group concluded that gasoline exhaust was possibly carcinogenic to humans Group 2B a finding unchanged from the previous evaluation in 1989. Public health Large populations are exposed to diesel exhaust in everyday life whether through their occupation or through the ambient air. People are exposed not only to motor vehicle .
