Hypothesis
What is the impact of breast cancer deaths on overall mortality in Catalonia by age and birth cohort?
Conclusion
The study quantified the effect of removing breast cancer mortality and found that its impact on overall mortality decreased for cohorts born after 1955.
Supporting Evidence
- Breast cancer accounts for a fifth of all female cancer deaths in Catalonia.
- Mortality from all causes in women has been decreasing by an average of 1.6% per year since 1978.
- Breast cancer mortality started to decrease in the early 1990s, concurrent with the dissemination of mammography.
Takeaway
This study looked at how many women die from breast cancer compared to other causes in Catalonia, and found that breast cancer has a big impact on deaths for women in their 40s and 50s.
Methodology
The study used multi-decrement life table methodology to assess mortality probabilities by age and cohort.
Potential Biases
The method used may not account for the interdependence of different causes of death.
Limitations
The study assumes independence of causes of death, which may not be true, and there may be errors in data from earlier years.
Participant Demographics
The study focused on women in Catalonia, specifically those born between 1900 and 2004.
