Rate differences between first and second primary cancers may outline immune dysfunction as a key risk factor
Background: Many cancers are increased in immunosuppressed patients and evidence is accumulating that immune dysfunction may be a contributing risk factor for second primary cancers (SPCs). The aim of this study was to explore the potential influence of immune mechanisms in SPC. Methods: We used the Swedish Cancer Registry (1990-2015) to select 13 male and 14 female first primary cancers (FPCs) th
