The incidence of Non-Hodgkin’s Lymphoma has nearly doubled in the last 30 years.  Much of this increase is thought to be due to environmental exposure to carcinogens.

We occasionally get contacted by people who have been exposed directly to pesticides.  Their question…did that exposure cause their blood disease (aplastic anemia, NHL, AML, etc.)?  Usually we cannot connect the pesticide to the blood disease.  BUT  If they were exposed to the process of making the pesticide, then they might have a case.

The reason is that benzene in some form is used in making pesticides.

See this article in the Billings Gazette talking about a few people who are suing over just that.
