Benzene Proximity Linked to Increased Lymphoma Risk
Non-Hodgkin's lymphoma risk falls by 0.3 percent with each mile increase in proximity
MONDAY, July 29 (HealthDay News) -- Proximity to benzene release sites in metropolitan areas of Georgia are associated with an increased risk of non-Hodgkin's lymphoma, according to a study published online July 29 in Cancer.
Catherine Bulka, M.P.H., from Emory University in Atlanta, and colleagues analyzed several databases to identify patterns of cases of non-Hodgkin's lymphoma based on proximity to benzene release sites in Georgia from 1988 to 1998.
The researchers found that the risk of non-Hodgkin's lymphoma fell by about 0.3 percent with each average increase of one mile from a benzene release site, with similar results for all subtypes. Benzene release sites associated with increased cancer incidence were either in the metropolitan Atlanta area or near Savannah.
"Non-Hodgkin's lymphoma incidence was significantly higher in census tracts that were closer, on average, to benzene release sites," Bulka and colleagues conclude.
