Abstract

The relative risks of malignant lymphomas among road transport workers were investigated using the National Cancer Registry in England and Wales. Drivers of buses and coaches (OCC unit 120) had increased risks for both Hodgkin's and non-Hodgkin's lymphomas and the drivers of other road passenger vehicles (OCC unit 121) for Hodgkin's lymphomas only. Although the increased risks did not show statistical significance, they corresponded to and reinforced previously described findings based on occupational mortality.
