Research Identifies 485 Pesticide Chemicals Linked to Breast Cancer
Key points
- 485 chemicals in US pesticide products linked to breast cancer.
- Study published in Environmental Health Perspectives.
- Includes active and 'inert' pesticide ingredients.
- US EPA regulation focuses on individual ingredients, not full formulas.
Pesticide Chemicals Linked to Breast Cancer
New research has identified at least 485 chemicals present in US pesticide products that are associated with breast cancer. This finding comes from a peer-reviewed paper published in Environmental Health Perspectives, a journal from the American Chemical Society.
Regulatory Deficiencies Highlighted
The study points to deficiencies in how pesticides are regulated in the US. The Environmental Protection Agency (EPA) primarily assesses the health risks of individual pesticide ingredients and does not evaluate entire pesticide formulas or the effects of exposure to multiple pesticides. This includes hundreds of 'inert' ingredients that typically do not undergo thorough safety reviews.
Only about 145 of the identified pesticide chemicals were registered with the EPA as active ingredients, suggesting that the 'inert' status may be used to bypass health scrutiny.
Widespread Exposure and Rising Cancer Rates
These chemicals are found in various products beyond agricultural use, including lice treatments, home lawn fertilizers, and flea and tick treatments. Jenny Kay, a co-author from the Silent Spring Institute, noted the cumulative impact of these exposures.
Breast cancer incidence rates in the US have increased by 1% annually, with a slightly faster rise (1.4%) in women under 50. Federal health data indicates that 84 of these breast cancer-linked chemicals are present in the general population, though scientists believe this is an undercount.
Broader Research Context
This pesticide review is part of a larger effort by the Silent Spring Institute to identify sources of breast cancer-linked chemical exposure in everyday life. Previous work by the institute identified approximately 500 such chemicals in common consumer goods and 462 in drinking water.

Reporting from
A new peer-reviewed study published in Environmental Health Perspectives identified 485 chemicals in US pesticide products, including active and 'inert' ingredients, linked to breast cancer. This research raises concerns about pesticide regulation and potential links to increasing breast cancer rates, particularly in younger women.
