Doctors and researchers have monitored rising colon cancer rates among young people. In the United States, colorectal cancer rates increased by 3 percent annually among adults aged 20 to 49 between 2013 and 2022.

A study by researchers at Central South University in China found that long-term exposure to polystyrene nanoplastics promoted tumor growth in mice predisposed to colon cancer. The particles accumulated in the colon, disrupted gut cells and affected the balance of gut bacteria.

Other studies have also found higher concentrations of microplastics in colorectal cancer tumors compared with nearby healthy tissue.

Researchers say further investigation is needed to establish a clear link between microplastics and colorectal cancer.

Meanwhile, they recommend early screenings to detect and remove precancerous growths. People can also reduce exposure by avoiding heating food and drinks in plastic containers, as heat can increase the release of chemicals.
