Risk of non-Hodgkin's lymphoma following tuberculosis.
To study the association between chronic infections and non-Hodgkin's lymphoma (NHL), we assessed the risk of NHL in a Swedish cohort of 5050 individuals with tuberculosis 1939-1960. The overall relative risk was moderately increased, largely accounted for by high risks following severe tuberculosis diagnosed a long time ago.
