Plastic has become part of everyday life. It is used in food containers, water bottles, clothing, packaging, electronics, and countless household products.
Over time, these materials break down into extremely small pieces called microplastics, which are so tiny that they can only be seen with special equipment. Scientists have recently discovered that these particles are not just in the environment but also inside the human body.
A new study now suggests that microplastics may even be linked to prostate cancer, one of the most common cancers affecting men.
The research was conducted by a team at NYU Langone Health. They examined tissue samples from men who had surgery to remove the prostate because of cancer. The prostate is a small gland located below the bladder that plays a role in reproduction.
Prostate cancer often develops slowly, but in some cases it can grow aggressively and spread to other parts of the body. According to health experts, about one in eight men will be diagnosed with this cancer during their lifetime.
When the scientists analyzed the tissue samples, they found microplastic particles in nine out of ten tumor samples. Even more surprising, the amount of plastic in cancerous tissue was much higher than in nearby healthy tissue.
On average, tumors contained more than twice as much plastic as noncancerous areas. This difference raised questions about whether long-term exposure to microplastics could play a role in the development of the disease.
Microplastics can enter the body in several ways. People may swallow them in food or water, breathe them in from polluted air, or absorb them through the skin. These particles come from many sources, including degraded packaging, synthetic clothing fibers, cosmetics, and industrial waste.
Previous studies have already found microplastics in the lungs, blood, liver, and even in unborn babies. However, scientists still do not fully understand what these particles do once they are inside the body.
To make sure their results were accurate, the research team took special precautions to avoid contamination during testing. They avoided using plastic tools and worked in carefully controlled clean rooms.
They also used advanced instruments to identify the chemical makeup and structure of the particles. This careful approach strengthens confidence that the plastics truly came from the tissue samples and not from the laboratory environment.
One possible explanation for the link between microplastics and cancer involves inflammation. When foreign particles enter the body, the immune system may react to them. If this reaction continues for a long time, it can damage nearby cells and increase the risk of abnormal growth.
Chronic inflammation has been linked to several types of cancer, so scientists believe it could also play a role here. However, the researchers stress that this was a small study and does not prove that microplastics cause prostate cancer. Larger studies will be needed to confirm the connection and understand the mechanisms involved.
In reviewing the findings, it is important to recognize both their significance and their limitations. The discovery of high levels of microplastics in tumors is concerning because it suggests a possible environmental factor that has not been widely considered before.
At the same time, the study included only a small number of patients, so the results cannot yet be applied to the general population. Future research will need to examine larger groups of men and track exposure levels over time to determine whether microplastics truly increase cancer risk.
Even without final answers, the study highlights how widespread plastic pollution has become and how it may affect human health in ways we are only beginning to understand.
Reducing plastic use, improving recycling systems, and limiting exposure to contaminated air and food may become increasingly important as scientists learn more. This research opens the door to new questions about environmental health and the hidden impact of modern materials on the human body.
