Can brief but direct exposure to toxic pest-control chemicals cause Acute Myelogenous Leukemia?

Snack bar worker exposed to pest-control chemical by worker in a hazmat suit. Became deathly ill shortly after exposure and within 2-3 weeks was diagnosed with AML.Can brief but direct exposure to toxic pest-control chemicals cause Acute Myelogenous Leukemia?
the term toxic should be enough no one knows what CAN cause what and there is the individual variation something can affect 1 in a million (SORRY AT WORK) and leave the other 999,999 untouched but if this goes to court you have 0% Chance without a documented history of cause and effectCan brief but direct exposure to toxic pest-control chemicals cause Acute Myelogenous Leukemia?
I have not seen this reported. I would be skeptical. So many things have been blamed for causing cancer and leukemia and only a small percentage proved correct.
There have been proven links between certain radiations and leukemia type cancers. There has also been a proven link between the chemical Benzene and cancer. There may be other links between cancer and chemicals that I am not aware of. The best way to determine this is with the MSDS information from the chemical. A MSDS sheet is the Material Safety Data Sheet and it contains a list of all the ingredients and ALL the hazards and treatment due to exposure of that chemical. I would contact the pest control company for a copy of the MSDS sheet or contact OSHA for help.
