Mortality from Breast Cancer
•
Unlike comparisons of survival, comparisons of
mortality rates are not distorted by variations
screening programmes and earlier diagnosis.
•
Trends and comparisons of breast cancer
mortality rates are therefore easier to interpret
than incidence rates
•
They will reflect:
–
Underlying disease rates
–
Biological impact of early diagnosis, without distortion
–
Efficacy, availability, and uptake of treatment
