Changes in period and cohort effects on haematological cancer mortality in Spain 1952-2006

摘要

BackgroundIn contrast to other haematological cancers, mortality from non-Hodgkin’s lymphoma and multiple myeloma increased dramatically during the second half of the 20th century in most developed countries. This widespread upward trend remains controversial, as it may be attributable either to progressive improvements in diagnosis and certification or to increasing exposures to little-known but relevant risk factors.
