Pesticides are widely used in agriculture, parks, and gardens to control insects, fungi, and weeds. According to the organization Beyond Pesticides, these chemicals often come with health concerns, many of which are linked to various forms of cancer and are still poorly understood.
Not all pesticides are considered carcinogens, and some chemicals have insufficient research to determine whether they are safe. According to the World Health Organization (WHO), people are exposed to pesticides through water and food, but exposure levels are generally considered to be low, according to a report by the European Food Safety Authority.
2026 paper American Association for Cancer Research has sounded the alarm about the link between eating “healthy foods” such as fruits and vegetables and early-onset lung cancer due to the presence of pesticides. However, this paper is based on a small sample and uses indirect measures of pesticide exposure. That means it’s a possible connection that requires deeper study.
These health concerns have already led to bans on many pesticides in some regions. In the European Union, pesticides such as dimethomorph, bentiavaricarb, ipconazole, and oxamyl Limited. These chemicals are part of a group known as the “toxic 12.” Glyphosate, a chemical used in common herbicides, has also long been controversial due to suspected cancer risks, according to the Pesticide Action Network.
2026 natural health This study sheds further light on this issue and highlights serious concerns about high radiation exposure and the occurrence of certain cancers at the national level. It also highlights that even when pesticides are considered “safe,” exposure to multiple chemicals can be a problem.
“This highlights a global concern, because pesticides are used everywhere,” said Stéphane Bertani, a molecular biology researcher at France’s National Institute for Sustainable Development and co-author of the paper. natural health paper, said discover. “For us, this type of research should be carried out in other countries as well.”
Examining pesticides and cancer risk
First, the researchers looked at how pesticides spread into the environment in each region of Peru over a six-year period from 2014 to 2019. This allowed the team to create a map showing areas of high exposure. They then used a database of 150,000 patients to identify areas of exposure and associated cancer risks. They found that, on average, exposure to pesticides increased the risk of developing cancer by 150%. As part of their study, they looked at about 30 different pesticides.
Most importantly, Dr. Jorge Honres. in epidemiology from the University of Toulouse, and natural health paper, said discover None of the chemicals analyzed by the research team are considered carcinogens on their own.
“The problem seems to be in the mixture,” he said. “Previous research has focused on testing one pesticide at a time in a laboratory setting. The problem is not how people are actually exposed in the real world; they are surrounded by a mixture of dozens of pesticides at the same time.”
From previous research natural medicine It also suggests that exposure to pesticides such as picloram may be associated with an increase in early-onset colon cancer in people under age 50. This significant increase in recent years is poorly understood, and one hypothesis, along with changes in diet and smoking rates, is exposure to pesticides.
However, it is known that agricultural workers exposed to high levels of pesticides are at a much higher risk of developing various cancers, including breast and lung cancer. Another previous study published in frontier Based on data from the United States, they assessed that living in areas where pesticides are heavily used can increase cancer risk as much as smoking.

Climate change could accelerate the spread of chemicals
The researchers assessed that, on average, people in the study area were exposed to about 12 different pesticides. They highlight that climate change may exacerbate the problem in some cases by increasing exposure rates and changing the way chemicals are spread.
“Extreme weather events also change the way farmers use chemicals,” Honres says. “Additional pesticides may be applied to protect crops from pests that thrive in the heat.”
Researchers also found that these pesticide mixtures can disrupt liver cell function and processes that help maintain cell identity. In that case, the organ may become more vulnerable to infection and inflammation. Exposure leaves behind what Honreth describes as “molecular” scars. According to research, these chemicals can also damage your DNA and disrupt your endocrine system. Nature Reviews Endocrinology.
“We found that genes in healthy-looking liver tissue were already disrupted before cancer formed,” Honreth said. “So the damage begins quietly years before diagnosis.”
