ENVIRONMENTAL INFLUENCES ON THE EMERGENCE OF LUNG TUMORS

Introduction Lung cancer is one of the leading causes of cancer death worldwide. Environmental factors have a significant impact on the development of this disease. This summary examines the influence of smoking, passive smoke, and exposure to toxic substances on the incidence of lung cancer. Material and method Our work is based on a retrospective epidemiological study using patient data recorded in cancer registers of several oncology institutions at the city level of Oran. Environmental information was collected from databases and interrogation with patients with lung cancer. The statistical analysis was carried out to identify correlations between the incidence of lung cancer and levels of exposure to these environmental factors, adjusting for confusing variables such as age, sex and smoking. Results and discussion Analysis of the results of various studies shows a significant association between smoking and the onset of lung cancer. Furthermore, workers in different sectors such as transport, industry and construction are more likely to develop lung cancer than those working in sectors that are less exposed to smoke and steam such as welding vapors. This study confirms that, in addition to smoking, environmental factors contribute significantly to the incidence of lung cancer. Air pollution and occupational exposure to toxic agents represent substantial and modifiable risks. The results underline the importance of public health policies aimed at reducing air pollution and protecting workers from exposure to carcinogenic substances. Conclusion Environmental factors play a crucial role in the etiology of lung cancer. This study highlights the need for preventive measures and rigorous policies to minimize exposure to these risks in order to reduce the overall burden of lung cancer.
