The principal risk factor for lung cancer is smoking, which is largely responsible for the development of the disease in men and women. It is estimated that 10-15% of all deaths from lung cancer in the USA are caused by risk factors other than smoking. In isolation, these would account for 16,000-24,000 deaths per year, which would still place lung cancer among the ten most deadly forms of cancer.(3) Occupational carcinogens can act alone or in synergy with smoking. A review of lung cancer in Brazil discussed the principal risk factors, notably smoking, and the economic sectors where carcinogens are strongly present. The economic sectors listed included
IntroductionCarcinogens are often found in the workplace. Until the 1970s, most of the known human carcinogens were encountered in the workplace. The work environment remains a significant source of carcinogens.( 1) Carcinogenesis is a multifactorial process in which there is interaction among hereditary, genetic, and environmental factors that lead to uncontrolled cell growth. From this standpoint, occupational cancer is not considered a typical occupational disease, but rather a disease in which work, as an environmental factor, plays a decisive pathogenic role, by Schilling's criteria, which will be discussed below.
AbstractLung cancer is a multifactorial disease. Hereditary, genetic, and environmental factors interact in its genesis. The principal risk factor for lung cancer is smoking. However, the workplace provides an environment in which there is a risk of exposure to carcinogens. The International Agency for Research on Cancer currently lists 19 substances/work situations/occupations that have been proven to be associated with lung cancer (group 1). Thorough occupational history taking is not widely practiced in patients with lung cancer, which has a negative impact on the investigation of causality and, consequently, on the identification of cases of occupational cancer. The objectives of this review were to list the agents that are recognized as causes of lung cancer, to discuss the contribution of occupation to the development of the disease, to cite national studies on the subject, and to propose a list of procedures that are essential to the appropriate investigation of causality between lung cancer and occupation.Keywords: Lung neoplasms; Occupational diseases; Occupations; Carcinogens.
ResumoO câncer de pulmão é multicausal. Fatores hereditários, genéticos e ambientais interagem na sua gênese. O principal fator de risco é o tabagismo. Entretanto, o ambiente de trabalho é um local de possível exposição a agentes cancerígenos. Atualmente, a International Agency for Research on Cancer lista 19 substâncias/situações de trabalho/ocupações comprovadamente associadas ao câncer de pulmão (grupo 1). A abordagem da ocupação em pacientes portadores de câncer de pulmão é fraca, impactando negativamente na busca da causalidade e, consequentemente, no desvelamento de casos de câncer ocupacional. Os objetivos desta revisão foram elencar os agentes reconhecidame...
