Incidence of Non-Hodgkin's Lymphoma in Sweden, Denmark, and Finland from 1960 through 2003: an Epidemic That Was

Abstract
Background: Reports during the early 1990s indicated non-Hodgkin's lymphoma (NHL) as one of the most rapidly increasing malignancies. More recent trends remain poorly characterized, as do the underlying reasons for NHL time trends, in particular, the effect of changes in classification and registration of lymphoproliferative malignancies. Insights into the descriptive epidemiology of NHL may shed light upon its elusive etiology.
