Flexible parametric hazard models were used to estimate net survival and the excess hazard of dying from breast cancer up to 3 years after diagnosis.<h4>Results</h4>Age-standardised 3-year net survival was 87-89% in the UK and Denmark, and 91-94% in the other four countries. Stage at diagnosis was relatively advanced in Denmark: only 30% of women had Tumour, Nodes,British journal of cancerBreast cancer survival and stage at diagnosis in Australia, Canada, Denmark, Norway, Sweden and the UK, 2000-2007: a population-based study.PMC361908016148C1336/A1170011700Steward JAndersen OBrostrom STracey EICBP Module 1 Working GroupColdman AShin JHosbond CHatcher JWalters SQuin NMacDonald ABergh JWarnberg FButler JJohannesen TBMiddleton RLambe MRussell CMarrett LMilnes KHanson JKaasa SColeman MPRachet BMcLaughlin JEngholm GLagord CGunnarsson GMaringe CNishri DAdolfsson JMcGahan CEThomas BLee MMoneypenny IGjerstorff MLHarper TWist EFornander TTurner DBoyages JGavin AKirk SBarrett-Lee PChristiansen PAllemani CSherar MRabenek LLawrence GDhaliwal DForman DRichards MACurrow DPorter GMeechan DBryant HfalseBreast cancer survival and stage at diagnosis in Australia, Canada, Denmark, Norway, Sweden and the UK, 2000-2007: a population-based study.<h4>Background</h4>We investigate whether differences in breast cancer survival in six high-income countries can be explained by differences in stage at diagnosis using routine data from population-based cancer registries.<h4>Methods</h4>We analysed the data on 257,362 women diagnosed with breast cancer during 2000-7 and registered in 13 population-based cancer registries in Australia, Canada, Denmark, Norway, Sweden and the UK.
