Brief Summary

Gas station workers are exposed to carcinogenic substances.This increases risk of their exposure to hematological diseases such as lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), myelodysplastic syndromes (MDS), and myelogenous leukemia (AML), as well as different forms of non-Hodgkin's lymphoma (NHL) and multiple myeloma. Thus, the early identification of this condition between the gas station workers may prevent the hematological disease progression.
