They conclude that a combination of socioeconomic and lifestyle factors, and possibly tumor characteristics, are likely to contribute to the differences in stage at breast cancer presentation and survival rates by race and ethnicity, but these results are able to be checked in continents, nations, and regions. Differences in survival have been reported among American and European breast cancer patients. Europeans had a significantly lower 5-year relative survival rates compared with Americans (73% vs 82%).2 Moreover, differences in stage and therapy were reported across Europe, where Estonia, England, and Spain had the most advanced stage at diagnosis (39.3%, 21.1%, and 16.2%, respectively).3 . . .
