Rethinking the rise of early-onset gastrointestinal cancers: a call to action

A multidisciplinary team of researchers is raising the alarm about a dramatic increase in gastrointestinal cancers in people under 50 since the early 1990s, including colorectal, stomach, and pancreatic cancers. The causes remain poorly understood, but the researchers call for studying environmental exposures including the full range of chemicals people encounter throughout their lives. While the paper does not name microplastics specifically, the rise in early-onset GI cancers coincides with increasing environmental plastic pollution, and the gut is a primary site of microplastic accumulation in the body.

Microplastics and Colorectal Cancer: Presence in Human Colorectal Tissues and Associations with Tumor Biology- A Systematic Review

This review of 13 studies found that tiny plastic particles called microplastics are present in human colon tissues, with higher amounts found in cancerous tumors compared to healthy tissue. The research suggests these plastic particles may contribute to colon cancer development by causing inflammation and creating conditions that help tumors grow. While more research is needed to prove a direct cause-and-effect relationship, this highlights growing concerns about how plastic pollution in our environment and food supply might affect human health.

Microplastics in Early Onset Carcinogenesis

This review examines the emerging hypothesis that chronic microplastic exposure may contribute to cancer risk, noting that these particles provoke oxidative stress, inflammation, DNA damage, and microbiome disruption. Researchers highlight a temporal overlap between rising plastic production since the 1950s and increasing rates of early-onset cancers, though a causal link has not been established. The study suggests that lifelong microplastic exposure beginning in utero warrants further investigation as a potential contributing factor.

Microplastics: An emerging environmental risk factor for gut microbiota dysbiosis and cancer development?

This review examines how microplastics may disrupt the gut microbiome and immune system in ways that could promote cancer development. Evidence from recent studies suggests microplastics can cause chronic inflammation, alter the balance of gut bacteria, and trigger molecular pathways linked to several cancer types including lung, liver, breast, and colon cancer. While more human research is needed, the review highlights a concerning connection between microplastic exposure, gut health, and cancer risk.
