    Objective: To analyze and systematize the evidence on occupational asbestos exposure and the risk of lung cancer in workers. Materials and Methods: This is a qualitative study with systematic reviews, meta-analysis, and cohort designs, using databases such as PubMed NCBI, Redalyc, and Cochrane, with articles not older than 10 years and in English. Results: A total of 30 articles were analyzed, with a sample of 10 articles. Of these, 30% (3) were systematic reviews, 10% (1) were meta-analyses, and 60% (6) were cohort studies. The systematic reviews were international, with 40% (4) from the United States, 20% (2) from the Netherlands, 20% (2) from China, 10% (1) from Italy, and 10% (1) from Denmark. Conclusions: According to the 10 reviewed articles, 100% concluded that occupational exposure to asbestos increases the risk of lung cancer in workers. The relative risk increases by 1% to 4% per fiber-year (FY) / ml of exposure, and even at low levels of exposure, the relative risk of lung cancer is elevated. Other cancers by gender also increased: men showed a higher risk of lung and laryngeal cancers, while women showed a higher risk of ovarian cancer. Significantly increased lung cancer rates were associated with cumulative fiber exposure.
