In 2010, cancer deaths accounted for more than 15% of all deaths worldwide, and this fraction is estimated to rise in the coming years. Increased cancer mortality has been observed in immigrant populations, but a comprehensive analysis by country of birth has not been conducted. We followed all individuals living in Sweden between 1961 and 2009 7,109,327 men and 6,958,714 women, and calculated crude cancer mortality rates and age-standardized rates ASRs using the world population for standardization. We observed a downward trend in all-site ASRs over the past two decades in men regardless of country of birth but no such trend was found in women. All-site cancer mortality increased with decreasing levels of education regardless of sex and country of birth p for trend <0.001. We also compared cancer mortality rates among foreign-born 13.9% and Sweden-born 86.1% individuals and determined the effect of education level and sex estimated by mortality rate ratios MRRs using multivariable Poisson regression. All-site cancer mortality was slightly higher among foreign-born than Sweden-born men MRR = 1.05, 95% confidence interval 1.04–1.07, but similar mortality risks was found among foreign-born and Sweden-born women. Men born in Angola, Laos, and Cambodia had the highest cancer mortality risk. Women born in all countries except Iceland, Denmark, and Mexico had a similar or smaller risk than women born in Sweden. Cancer-specific mortality analysis showed an increased risk for cervical and lung cancer in both sexes but a decreased risk for colon, breast, and prostate cancer mortality among foreign-born compared with Sweden-born individuals. Further studies are required to fully understand the causes of the observed inequalities in mortality across levels of education and countries of birth.
