Abstract

While lifestyle choices or behavioral patterns remain the most significant factors influencing cancer risk, environmental exposure to certain chemicals, both manufactured and natural, may also contribute to an individual's likelihood of developing cancer. This interplay of factors, coupled with an aging demographic and shifting lifestyle patterns, has led to an increasing prevalence of cancer in recent years. This study examines the environmental and behavioral factors that contribute to anomalies in the immune system and increase the risk of developing cancer. Significant environmental and occupational factors include the contamination of air and water, exposure to radiation, contact with harmful microorganisms and pathogens, and workplace exposure to carcinogens such as asbestos, certain chemicals, and industrial pollutants. Behavioral factors, such as food, physical activity, stress, substance misuse, and sleep patterns, have a substantial impact on immunological function and the likelihood of developing cancer. For example, pollutants like benzene and arsenic can disrupt immune function and raise the risk of developing cancer. Similarly, lifestyle variables such as inactivity and poor nutrition have been linked to an increased risk of cancer. Long-term stress and substance abuse can also decrease immunological responses, increasing the risk of developing cancer. The review underlines the complexities of examining gene-environment interactions, as well as the importance of using several perspectives to fully comprehend these pathways. Future investigations should emphasize improved methodology and larger sample sizes. Public health campaigns should aim to reduce human exposure to cancer-causing compounds known as carcinogens while also encouraging the adoption of healthy behaviors and habits. Tailored preventive approaches that account for individual genetic vulnerabilities have the potential to improve cancer prevention and treatment.

In plain English

This article was a narrative review, not an original study. The authors gathered published research on how environmental and behavioral factors may affect the immune system and cancer risk. Topics included air and water pollution (including benzene and arsenic), radiation, infections, climate change, workplace carcinogens, diet and physical activity, stress, substance use, and sleep. Asbestos appeared only briefly. A table of cancer risk factors listed "asbestos and other substances" among risk factors for lung cancer. A table of workplace carcinogens paired asbestos with construction workers and named lung cancer and mesothelioma as the related cancers. These table entries gave no numbers, fiber types, or study sources. The authors concluded that pollutants, radiation, microbial agents and lifestyle choices significantly affect immune function and cancer development. They called for public health efforts to reduce exposure to carcinogens, promote healthy lifestyles and improve early detection. They also wrote that research in this field is hampered by complex exposures and inconsistent measurement.

We wrote this plain-English summary from the full article with the help of AI, and a second AI model checked each sentence against the article. It is not the authors' wording; the abstract and the article are their own account.

What the study did and found

• Design: narrative review of published literature (no original data collected)
• Exposure: A broad range of environmental, occupational and behavioral factors. Asbestos was listed among workplace carcinogens.
• Main results:
  • A table of workplace carcinogens listed asbestos, with construction workers as the occupation and lung cancer and mesothelioma as the associated cancer types. No numbers, fiber types or source were given.
  • A table of cancer risk factors listed asbestos among the risk factors for lung cancer.
  • The authors identified research challenges in this field, including the complexity of exposures and inconsistent measurement.
• The authors' conclusion: The authors concluded that pollutants, radiation, microbial agents and lifestyle choices significantly affect immune function and cancer development. They stated that public health efforts should focus on reducing carcinogen exposure, promoting healthy lifestyles and improving early detection.
