Micro(nano)plastics pollution and human health: How plastics can induce carcinogenesis to humans?
AI summary Read the abstract
This review examines how microplastics and nanoplastics enter the human body through food, water, and air, and how they may contribute to cancer development. Common plastic types like polystyrene and PVC, along with toxic chemicals they carry such as PAHs and PCBs, have been linked to DNA damage, oxidative stress, and inflammation, all of which can promote cancer. The paper highlights that while the evidence is growing, more research is needed to understand the full cancer risk from chronic microplastic exposure.
Microplastics (MPs) and nanoplastics (NPs) are key indicators of the plasticine era, widely spread across different ecosystems. MPs and NPs become global stressors due to their inherent physicochemical characteristics and potential impact on ecosystems and humans. MPs and NPs have been exposed to humans via various pathways, such as tap water, bottled water, seafood, beverages, milk, fish, salts, fruits, and vegetables. This paper highlights MPs and NPs pathways to the food chains and how these plastic particles can cause risks to human health. MPs have been evident in vivo and vitro and have been at health risks, such as respiratory, immune, reproductive, and digestive systems. The present work emphasizes how various MPs and NPs, and associated toxic chemicals, such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), impact human health. Polystyrene (PS) and polyvinyl chloride (PVC) are common MPs and NPs, reported in human implants via ingestion, inhalation, and dermal exposure, which can cause carcinogenesis, according to Agency for Toxic Substances and Disease Registry (ATSDR) reports. Inhalation, ingestion, and dermal exposure-response cause genotoxicity, cell division and viability, cytotoxicity, oxidative stress induction, metabolism disruption, DNA damage, inflammation, and immunological responses in humans. Lastly, this review work concluded with current knowledge on potential risks to human health and knowledge gaps with recommendations for further investigation in this field.

Microscopic menace: exploring the link between microplastics and cancer pathogenesis
AI summary Read the abstract
This review examines the growing evidence linking microplastic exposure to cancer development in humans. Microplastics can accumulate in the body and trigger inflammation, oxidative stress, and other biological changes associated with tumor growth. While more clinical research is needed, the review highlights that microplastics should be taken seriously as a potential factor in cancer risk.
Do microplastics (MPs) and nanoplastics (NPs) directly contribute to human carcinogenesis?
AI summary Read the abstract
This review examines whether microplastics and nanoplastics could directly contribute to cancer development in humans. Evidence from lab and animal studies shows these particles can cause DNA damage, chronic inflammation, oxidative stress, and disrupt important cancer-related signaling pathways. While a direct causal link to human cancer has not been proven yet, the review argues that microplastics should be considered potential cancer-promoting agents that warrant urgent further research.
Microplastic-induced carcinogenesis: Molecular mechanisms, cellular interactions, and toxicological implications
AI summary Read the abstract
Tiny plastic particles that we breathe, eat, and touch every day are now showing up in our blood, lungs, and other organs, and this review of existing research explains how they might contribute to cancer. Microplastics can trigger cell damage, inflammation, and disrupted signaling in ways linked to tumor growth, and they can also act like tiny rafts that ferry other harmful chemicals and toxins deeper into our bodies. While scientists haven't proven microplastics directly cause cancer in humans yet, the mounting evidence is a strong signal that reducing plastic exposure and pushing for more research should be a public health pri
The impact of environmental microplastics as emerging carcinogens: A public health concern
AI summary Read the abstract
This review investigated the mechanisms by which microplastics may contribute to cancer development, examining studies from 2010 to 2024. Researchers found that microplastics can induce oxidative stress, inflammation, and DNA damage through multiple pathways, and that human exposure occurs primarily through ingestion, inhalation, and dermal contact. The study suggests that microplastics represent an emerging class of environmental concern warranting further investigation into their long-term health effects.
