While genetic factors play a crucial role in cancer development, environmental and anthropogenic carcinogens have emerged as significant contributors to the rising cancer burden. Environmental carcinogens are substances present in the natural environment, while anthropogenic carcinogens are those generated by human activities, such as industrial processes, transportation, and agricultural practices. Exposure to these carcinogens can lead to the initiation, promotion, and progression of cancerous cells, thereby increasing the risk of various malignancies. The sources and pathways of exposure to environmental and anthropogenic carcinogens are diverse and widespread. Air pollutants from vehicular emissions, industrial emissions, and combustion processes introduce carcinogenic substances into the atmosphere, which can be inhaled or deposited on surfaces, subsequently exposing human populations. Industrial chemicals, such as benzene and formaldehyde, are prevalent in workplaces and consumer products, presenting occupational and consumer exposure risks. Pesticides, extensively used in agriculture to protect crops, may inadvertently contaminate food and water sources, leading to chronic exposure in humans. Tobacco smoke, a well-known human carcinogen, is a major cause of cancer-related deaths globally. Smoking and second-hand smoke expose individuals to a complex mixture of carcinogens, significantly elevating cancer risk in both smokers and non-smokers. Additionally, ionizing and non-ionizing radiation, originating from natural sources and human activities like medical imaging and telecommunication, have been associated with various types of cancer. Understanding the impact of these environmental and anthropogenic carcinogens on human health is vital for public health policies, prevention strategies, and cancer risk management. This study aims to provide a comprehensive review of the major environmental and anthropogenic carcinogens, their mechanisms of action, and their carcinogenic effects on humans. By synthesizing available epidemiological evidence and mechanistic studies, we aim to shed light on the significance of these carcinogens in cancer development and emphasize the need for effective mitigation measures to protect human health. METHOD Literature Review: A systematic literature review was conducted to identify relevant studies and publications on environmental and anthropogenic carcinogens and their impact on human health.

By employing this methodological approach, the study aims to present a comprehensive and evidence-based review of environmental and anthropogenic carcinogens, providing insights into their carcinogenic effects on humans and guiding future research directions for cancer prevention and risk management strategies. RESULTS The comprehensive review of environmental and anthropogenic carcinogens revealed a wide array of substances that pose significant risks to human health. Air pollutants, including polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), and heavy metals, were found to be pervasive in urban and industrial areas, leading to increased cancer risk, especially in individuals residing or working in proximity to pollution sources. Industrial chemicals, such as benzene, asbestos, and formaldehyde, were associated with occupational cancer hazards and potential consumer exposure through various products. Pesticides, particularly organophosphates and organochlorines, were identified as potential contributors to cancer development, especially in agricultural workers and those with contaminated https://doi.org/10.37547/ajbspi/Volume03Issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= Volume 03 Issue 09-2023 4 American Journal Of Biomedical Science & Pharmaceutical Innovation (ISSN – 2771-2753) VOLUME 03 ISSUE 09 PAGES: 1-5 SJIF IMPACT FACTOR (2021: 5. 705) (2022: 5. 705) (2023: 6.534) OCLC – 1121105677 Publisher: Oscar Publishing Services Servi food and water consumption. Tobacco smoke, containing numerous carcinogens like polycyclic aromatic hydrocarbons (PAHs) and nitrosamines, emerged as a leading cause of lung cancer and other malignancies in smokers and non-smokers exposed to second-hand smoke. Additionally, ionizing radiation, such as X-rays and gamma rays, was linked to an increased risk of leukemia, thyroid cancer, and solid tumors, while non-ionizing radiation from mobile phones and other electronic devices showed limited evidence of carcinogenicity. DISCUSSION The results of this study underscore the significant impact of environmental and anthropogenic carcinogens on human health. The findings emphasize the need for increased awareness of the sources and pathways of exposure to these carcinogens, as well as the importance of implementing effective preventive measures. For instance, regulatory efforts to reduce air pollution, improve workplace safety, and control the use of harmful chemicals and pesticides are essential for minimizing cancer risks in susceptible populations. Anti-smoking campaigns and policies aimed at reducing tobacco consumption and exposure to second-hand smoke play a pivotal role in curbing tobacco-related cancer incidence. Moreover, strict adherence to radiation safety guidelines in medical and occupational settings is critical to mitigating cancer risks associated with ionizing radiation exposure. The review of mechanistic studies provided insights into the underlying biological processes through which these carcinogens exert their carcinogenic effects. Carcinogens may induce DNA damage, activate oncogenes, suppress tumor suppressor genes, promote chronic inflammation, and alter epigenetic regulation, ultimately leading to uncontrolled cell growth and cancer development. Understanding these mechanisms facilitates the development of targeted interventions and therapeutic strategies to prevent or treat cancer. CONCLUSION Environmental and anthropogenic carcinogens pose substantial risks to human health, contributing to the increasing burden of cancer globally. The review highlighted the diverse sources and exposure pathways of these carcinogens, ranging from industrial processes and vehicular emissions to tobacco smoke and radiation exposure. The findings emphasize the importance of implementing evidence-based preventive measures and policies to reduce exposure and minimize cancer risks. Public health initiatives focused on raising awareness, improving environmental standards, and promoting healthy behaviors can play a pivotal role in mitigating the impact of these carcinogens on human health. Moreover, continued research is needed to identify emerging carcinogens, explore interactions between multiple carcinogens, and elucidate the mechanisms of https://doi.org/10.37547/ajbspi/Volume03Issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= Volume 03 Issue 09-2023 5 American Journal Of Biomedical Science & Pharmaceutical Innovation (ISSN – 2771-2753) VOLUME 03 ISSUE 09 PAGES: 1-5 SJIF IMPACT FACTOR (2021: 5. 705) (2022: 5. 705) (2023: 6.534) OCLC – 1121105677 Publisher: Oscar Publishing Services Servi action behind their carcinogenic effects.
