Research Report: Do Pesticides Cause Lymphoma?


Non-Hodgkin's lymphoma has been increasing so dramatically in the United States, scientists are calling it an "epidemic."

National Cancer Institute data show that people develop lymphoma most often in states and locations with the highest pesticide use ("hot spots").

Lymphoma Foundation of America's new report carefully examines all scientific studies worldwide on lymphoma and pesticides.

Lymphoma Foundation of America assembled a panel of nationally distinguished scientists and cancer experts to review these findings.

LFA's Report, a first-of-its-kind look at all the research studies, identifies commonly-used pesticides frequently associated with lymphoma incidence and/or deaths. It also describes ways people are exposed to pesticides in everyday life and suggests ways to avoid exposure.

The research studies include: adults and children; urban and rural locations; various occupations; and health effects of weed killers, insect killers, fungicides, fumigants, arsenic and other compounds.


The majority of 117 scientific studies and articles show an increase in lymphoma in populations with higher exposures to pesticides, especially weed killers.

Of Special Interest:

- A California study found increased lymphoma rates among children exposed to pesticides inside the home, including a subset of children exposed in the womb before birth.

- One of the studies has preliminary results re: lawn care company employees.

- Two case reports describe people who developed cancer after skin exposure to pesticides

Lymphoma Foundation of America
calls for a decrease in pesticide use and urges further study of the relationship between lymphoma and pesticides.

Lymphoma Foundation of America particularly wants more studies of farmers, the people who produce our nation's food and who are at the highest risk for lymphoma.

Lymphoma Foundation of America is calling on pesticide makers to develop safer pesticides that do not harm humans.

Lymphoma Foundation of America is calling for labeling on pesticide products to include a cancer warning.

Lymphoma Foundation of America is establishing a National Registry for lymphoma patients (survivors or deceased) who believe, or whose family members believe, that pesticides may have caused the cancer.

Lymphoma Foundation of America urges individuals to consider signing up for their state's consumer "pesticide notification program" so that they can be alerted when pesticides are applied near their homes.


Commonly used pesticides most frequently associated with increased lymphoma incidence and/or deaths in the studies:

2,4-D (2,4-dichlorophenoxyacetic acid)

Atrazine and other triazines (triazine herbicides are widely used on corn crops)

Also associated with increased lymphoma incidence and/or mortality:

1,3-dichloropropene phosphine

2,4,5-T (2,4, 5- trichlorophenoxyacetic acid) toxaphene

glyphosate-containing weed killers 4-chloro-2-methylphenoxyacetic acid

lindane [MCPA]

carbaryl stannates (tin-containing compounds

chlordane arsenates

diazinon dichlorvos



combinations of herbicides, insecticides, fumigants, or fungicides

PCBs (chemically similar to organochlorine pesticides)

various solvents, such as benzene

various occupations (farming, fencing, military, construction, and others) which involve chemical exposures.
