Using the CRIS-NCRAS linkage to investigate the association between multiple primary malignancies and severe mental illness (SMI)
Does pre-existing SMI affect the onset of secondary malignancies? Using the CRIS and cancer registry linkage (NCRAS), the project will compare the prevalence of secondary tumours in those with pre-existing SMI, such as schizophrenia, BPD, major depression, and psychosis, to those with other mental illnesses, such as eating disorders and anxiety, and a control group of no psychiatric comorbidities.
