Prostate cancer incidence and mortality among immigrants in Finland between 2000 and 2017 – a register-based cohort study

Non-Western men had a relative risk (RR) of 0.663 (95% confidence interval [CI] 0.609-0.722) for cases and 0.803 (0.646-0.997) for deaths. Western men had RRs of 0.876 (0.784-0.978) and 0.78 (0.567-1.072), respectively. A longer duration of residence and a younger age at immigration increased the risk for prostate cancer. Compared to the men born in Finland, both immigrant groups showed a lower risk of prostate cancer. Non-Western men may have also had a lower risk of death from it. Prostate cancer mortality in non-Western immigrants appears to be high compared to its incidence. While uncertain, this implication is concerning enough to warrant further research into the topic.
