RESUMO

Occupational factors can lead to breast cancer, though the relationship between these variables is not well established. The objective of this study was to search the relevant literature for information on the association between breast cancer and exposure to occupational risk factors. For that purpose, electronic databases were searched using the following keywords: breast cancer and occupational exposures. A total of 40 articles published in the 10-year period from 2009 to 2019 were included in this review. Workers exposed to metals such as cadmium, chemical products, radiation and night work were more susceptible to breast cancer. The findings showed significant evidence to support an association between breast cancer and some chemical products, ionizing radiation and night work. However, most studies have difficulty establishing a causal relationship between these variables, pointing to the need for further investigation of these issues.

RESUMO

BACKGROUND: Occupational risk factors are associated with many types of neoplasms including cervical cancer. OBJECTIVE: To review the specialized literature for evidence on the relationship between cervical cancer and exposure to occupational hazards. METHODS: Literature search in electronic databases using keywords cervical cancer and occupational risk. RESULTS: Workers occupationally exposed to tobacco, fungi or bacteria, metalworking fluids and tetrachloroethylene used in dry cleaning and for metal degreasing exhibited higher susceptibility to cervical cancer. CONCLUSION: Few studies sought to investigate relationships between cervical cancer and occupational hazards, which hinders the attempts at establishing a causal link.

INTRODUÇÃO: Fatores de risco associados ao trabalho podem causar, entre outros, câncer de colo uterino. OBJETIVO: Identificar na literatura especializada a associação entre câncer de colo de útero e a exposição aos fatores ocupacionais de risco. MÉTODOS: Realizou-se um levantamento bibliográfico em bases de dados eletrônicos com os seguintes descritores: câncer de colo uterino e riscos ocupacionais. RESULTADOS: Trabalhadores expostos ao tabaco nas fábricas de cigarro, fluidos de motores, exposição ocupacional a fungos e bactérias e ao tetracloroetileno, presente em produtos de limpeza usados em lavanderias e para desengraxar metais, estariam mais susceptíveis ao desenvolvimento de câncer de colo uterino. CONCLUSÃO: Há poucos estudos que identificam a relação entre o câncer de colo de útero e os fatores de risco ocupacional, dificultando a associação entre o carcinogênese e o fator de risco.
