(Beyond Pesticides, July 1, 2026) A review in the International Journal of Cancer links pesticide exposure, particularly in areas with high agricultural crop density, to increased risks for childhood cancers. The team of researchers from the University of Nebraska-Lincoln and University of Nebraska Medical Center, in analyzing epidemiologic studies published between January 1980 and September 2022, says that “this scoping review affirms that a robust body of epidemiology literature already informs how parental and childhood exposure to environmental chemical exposures can be associated with children’s incidence of pediatric leukemia and brain cancer.” The scientific literature shows that pediatric cancer, which is a significant cause of morbidity and mortality in children, is associated with exposure to residential pesticides, pesticides ingested through drinking water, parental exposure, and in areas with close proximity to agricultural areas where pesticides are used. Background According to the American Childhood Cancer Organization, over 15,000 children in the U.S. are diagnosed with cancer each year, with pediatric cancer as the second leading cause of death in children 5–9 years of age and the third leading cause of death in children ages 10–14. (See here.) In agricultural states, such as Nebraska, Iowa, Minnesota, Kansas, Illinois, Ohio, and Missouri, incidence […]

(Beyond Pesticides, December 10, 2025) On November 21, 2025, the International Agency for Research on Cancer (IARC), a branch of the World Health Organization (WHO), designated the endocrine-disrupting herbicide atrazine (as well as the herbicide alachlor) as “probably carcinogenic to humans.” Manufactured by the multinational, China-based pesticide corporation Syngenta, atrazine has been linked to various adverse health effects and runoff into waterways across the continental United States for years. Tyrone Hayes, PhD, researcher and professor of Integrative Biology at the University of California, Berkeley, who studies the endocrine-disrupting properties of atrazine and other chemicals, has said that atrazine induces cancer by turning on the enzyme aromatase. Dr. Hayes told conferees of Beyond Pesticides’ 31st National Pesticide Forum that: “[W]hat is concerning about aromatase expression and estrogen in mammals is breast cancer and prostate cancer. With regard to prostate cancer, there is an 8.4-fold increase in prostate cancer in men who work in atrazine factories and bag atrazine. There is at least one correlational study, which I didn’t publish, that shows women whose well water is contaminated with atrazine are more likely to develop breast cancer than women who live in the same community, but don’t drink the well water.

(Beyond Pesticides, July 14, 2025) With the rise in early onset cancer rates and mortality for breast, pancreatic, and gastric cancers, a wide and growing body of science linking pesticides to cancer, and associations between childhood cancer and pesticides, Beyond Pesticides is urging nationwide efforts to eliminate the use of cancer causing pesticides. Peter Hopewood, MD, FACS, writing in a bulletin in the American College of Surgeons says, “The coronavirus 2019 (COVID-19) pandemic has been in the healthcare spotlight since 2019, but the reality is that heart disease and cancer killed more people than COVID-19 in 2020 . . . and were our nation’s leading causes of death for decades before that. Among Americans younger than 85 years of age, cancer remains the leading cause of death.” Dr. Hopewood is convinced that “cancer has been an ongoing pandemic since life expectancy increased during the 20th century.”  In 1985, Imperial Chemical Industries and the American Cancer Society declared October “Breast Cancer Awareness Month” as part of a campaign to promote mammograms for the early detection of breast cancer. Unfortunately, most of us are all too aware of breast cancer. Detection and treatment of cancers do not solve the problem. A preventive approach is needed, not just awareness. Barbara Brenner, […]

(Beyond Pesticides, March 4, 2025) A study in GeoHealth of pediatric cancers in Nebraska links exposure to agricultural mixtures with the occurrence of these diseases. The authors find statistically significant positive associations between pesticide usage rates and children with cancer, specifically brain and central nervous system (CNS) cancers and leukemia. “Our study is the first to estimate the effect of an agrichemical mixture on the pediatric cancer rate in Nebraska,” the study authors share. “One significant advantage of our study is that we identified the pesticide consistently applied over 22 years in Nebraska counties and then estimated the overall mixture effect of these pesticides on pediatric cancer.” The elevated effect of pesticide mixtures, a reality that is not evaluated in the U.S. Environmental Protection Agency’s (EPA) pesticide registration program, was reported in Oecologia (2008), documenting harm to amphibian populations even if the concentration of the individual chemicals is within limits considered acceptable. (See additional coverage here.) There is a wide body of science highlighting the disproportionate risk of adverse health effects in children with pesticide exposure. Their small size and developing organ systems, propensity to crawl and play near the ground, tendency for frequent hand-to-mouth motion, and greater intake of […]

(Beyond Pesticides, October 10, 2024) On September 16, 2024, the U.S. Environmental Protection Agency (EPA) announced an order allowing Kaizen Technologies LLC to sell off its chlorpyrifos-based insecticide product—Bifenchlor, a known neurotoxicant. This reverses an existing stocks agreement that Kaizen voluntarily negotiated with EPA in August 2022 when the company withdrew Bifenchlor from use. The agency attributes this new order to a November 2023 Eighth Circuit Court of Appeals decision, which vacated EPA’s prior 2021 chlorpyrifos ban on food crops (see here). EPA’s practice of permitting the sale and use of existing stocks of canceled pesticides has been a longstanding concern for public health and environmental advocates, as it enables the continued use of petrochemical pesticides that the agency has found to be dangerous. Chlorpyrifos, an organophosphate with adverse health effects on children (see here and here), is now the latest example. In reporting on the almost unprecedented decision on August 7, 2024, to use its emergency authority to ban Dacthal/DCPA, Beyond Pesticides argues that the “Dacthal Standard” is a positive precedent, a step forward in modern regulatory history; however, EPA’s continued approval of chlorpyrifos’s existing stock, complicated by the 2023 court decision, may suggest otherwise.  As demonstrated historically with […]

(Beyond Pesticides, April 22, 2024) Today, on Earth Day, the future of the planet and the health of all its inhabitants come into focus from numerous human and ecosystem health perspectives, with particular concern for the health of the next generation—as childhood cancer continues to be a leading cause of death from disease among children. Many studies demonstrate an association between environmental or occupational pesticide exposure and the risk of childhood cancer in offspring. Taking Action in Your Community: On Earth Day, Beyond Pesticides invites communities to join together in its nationwide campaign to convert parks to organic land management practices through the Parks for a Sustainable Future program. Through this program, Beyond Pesticides works with park managers, bringing hands-on horticultural support to eliminate petrochemical pesticides and fertilizers and instead nurture soil organisms to cycle nutrients naturally while creating resilient landscapes that resist weeds, insects, and disease. This program outlines the steps to become a parks advocate and how Beyond Pesticides works with communities committed to safe parks and playing fields for communities, children, and pets. One major impetus for the Parks program are the many studies that find prenatal and early-life exposure to environmental toxicants increases disease susceptibility. For decades, studies have […]

(Beyond Pesticides, November 7, 2023) Two decades after the introduction of genetically engineered, herbicide-resistant crops and the consequential exponential growth in weed killers, Brazil is seeing an increase in childhood cancer. This is the conclusion reached in a comprehensive study spanning 15 years (2004-2019), “Agriculture Intensification and Childhood Cancer in Brazil,” published in Proceedings of the National Academy of Sciences (PNAS) in October. For the past 20 years, soybean herbicides have been killing and sickening children in the Cerrado and Amazon regions–where soybean cultivation is concentrated. The study reveals a link between an increase in soy cultivation and a spike in cases of acute lymphoblastic leukemia (ALL), the most common cancer affecting children, among indirectly exposed populations. Researchers identify pesticide-contaminated drinking water as the driving force behind the increased cancer rates occurring downstream from soybean sites. In 2003, Brazil legalized its first official genetically modified (GM) crop, welcoming the era of GM soybeans and sparking a radical transformation in its agricultural landscape–for better or worse. The introduction of Monsanto’s Roundup Ready soybean seed promised farmers an efficient and herbicide-resistant alternative to traditional crops. A significant shift occurred in the areas dedicated to soy cultivation in the Cerrado region, tripling from […]

(Beyond Pesticides, November 1, 2023) A study published in Environmental Health Perspective finds the risk of acute childhood leukemia (AL), specifically acute lymphoblastic leukemia (ALL), slightly increases with exposure to pesticides (i.e., insecticides and herbicides) from uses on vines, a crop subject to intensive pesticide use. Within 1 kilometer [km] of vineyards, the risk of ALL among children increases in areas with a higher density of vines. Although medical advancements in disease survival are more common nowadays, childhood AL remains the secondary cause of child mortality following physical injury. Furthermore, childhood leukemia survivors can suffer from chronic or long-term health complications that may be life-threatening. The etiology or cause of childhood AL involves the interaction of multiple components, including lifestyle and genetics; emerging evidence indicates that environmental contaminants (e.g., pesticides, air pollution, solvents, diet, etc.) play a role in disease. Pesticide contamination is widespread in all ecosystems, and chemical compounds can accumulate in human tissues, resulting in chronic health effects. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Already, studies find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects, from metabolic disorders to mental and physical disabilities. Moreover, […]

(Beyond Pesticides, September 21, 2023) A literature review published in CiĂŞncia & SaĂşde Coletiva finds environmental exposure to all classes of pesticides (fungicides, herbicides, insecticides) has an association with childhood astrocytoma (brain/central nervous system [CNS] tumor). CNS tumors represent half of all malignant neoplasms (tumors) in children. Although medical advancements in disease survival are progressing, childhood cancer remains the leading cause of death from disease among children. Furthermore, childhood cancer survivors can suffer from chronic or long-term health complications that may be life-threatening. The etiology or cause of childhood cancer involves the interaction of multiple components that include environment, lifestyle and genetics. However, emerging evidence indicates that environmental contaminants like pesticides (e.g., occupational exposures, air pollution, pesticides, solvents, diet, etc.) affect disease etiology. Pesticide contamination is widespread in all ecosystems, and chemical compounds can accumulate in human tissues, resulting in chronic health effects. Children are particularly vulnerable to the impacts of pesticide exposure, as their developing bodies cannot adequately combat exposure effects. Moreover, several studies demonstrate an association between environmental or occupational pesticide exposure and the risk of childhood cancer. Considering that maternal pesticide exposure can have a stronger association with cancer among children than childhood exposure, and newborns can still encounter pesticides, it is […]
