Cancer is the leading or second leading cause of premature death in 73% of countries, affecting individuals aged 30 to 69.In 2016, 29.8% of deaths from noncommunicable diseases were caused by cancer.In Brazil, 704 thousand new annual cases of cancer are projected between 2023 and 2025.Occupational exposure is a significant factor, with 19% of cancers related to the work environment.Underreporting and lack of adequate records make it difficult to assess the true extent of occupational cancers in Brazil.The objective of the study was to analyze the epidemiological profile of work-related cancer cases in Brazil between 2017 and 2022.An observational, descriptive and quantitative epidemiological research was carried out, using data from the Notifiable Diseases Information System (SINAN), available on the DATASUS.Data collection covered all registered cases of work-related cancer in Brazil between 2017 and 2022.Variables included age group, race, sex, exposure agents, occupation, ICD and evolution.The data was organized and analyzed in Excel, version 2020, and presented in graphs to facilitate understanding of the results.2,774 cases of work-related cancer were confirmed in Brazil between 2017 and 2022, with an annual average of 462.33 cases.2019 had the highest number of cases (791), while 2021 had the lowest ( 260), possibly due to the COVID-19 pandemic.The majority of cases occurred in men (67.23%) and in the age group of 65 to 79 years (37.49%).White individuals represented 66.33% of cases, with the occupation of agricultural worker being the most affected (17.41%).The most common types of cancer were other malignant neoplasms of the skin (ICD C44) and malignant neoplasms of the bronchi and lungs (ICD C34).Exposure to non-ionizing radiation was the most frequent (19.02%), and 39.17% of case evolution records were ignored.The study revealed an annual average of 462.33 cases of work-related cancer in Brazil, with a predominance of white men, aged 65 to 79 years, and agricultural occupations.The main cause was exposure to non-ionizing radiation, highlighting the need for greater attention and protective measures in the workplace.
