Air pollution plays a key role in lung cancer

Lung cancer is one of the most frequent causes of death on the planet, and among the various causes, air pollution plays an important role. The study Air pollution: A culprit of lung cancer, published in the Journal of hazardous materials, told: "Air pollution is a global health problem, especially in the context of rapid economic development and the expansion of urbanization.

Herein, we discuss the harmful effects of outdoor and indoor pollution on the lungs. Ambient particulate matters (PMs) from industrial and vehicle exhausts is associated with lung cancer.Workers exposed to asbestos, polycyclic aromatic hydrocarbons (PAHs), and toxic metals are also likely to develop lung cancer.

Indoors, cooking fumes, second-hand smoke, and radioactive products from house decoration materials play roles in the development of lung cancer.Bacteria and viruses can also be detrimental to health and are important risk factors in lung inflammation and cancer.Specific effects of lung cancer caused by air pollution are discussed in detail, including inflammation, DNA damage, and epigenetic regulation.

In addition, advanced materials for personal protection, as well as the current government policies to prevent air pollution, are summarized. This review provides a basis for future research on the relationship between lung cancer and air pollution."

Air pollution plays a key role in lung cancer

Lung cancer is a diagnostic category that includes the set of malignant neoplasms originating from the epithelial tissues that make up the bronchi and lung parenchyma.

Therefore, sarcomas and lymphomas originating in the context of pulmonary structures must be distinguished from this category. The majority (over 95%) of lung malignancies is represented by lung carcinoma, while sarcomas and lymphomas constitute less than 0.5% of this series.

Less than 5% of lung cancers are benign or low-grade tumors A further distinction must be made between primary neoplasms and secondary neoplasms. In fact, while the former originate from the lung structures, the latter are represented by metastases of neoplasms originating in other organs such as, for example, the kidney, liver, breast and prostate.
