Hypothesis
Breast cancer patients have an elevated risk of dying from breast cancer even after 20 years of survival.
Conclusion
Breast cancer patients who survive for 20 years still have a higher risk of dying from the disease despite having a normal life expectancy.
Supporting Evidence
- 47% of patients died from breast cancer after surviving at least 10 years.
- The standardized mortality ratio for breast cancer was 15.8 ten to fourteen years after diagnosis.
- The overall mortality was higher than expected ten to fourteen years after diagnosis.
Takeaway
Even if breast cancer patients live a long time, they can still die from breast cancer more than expected.
Methodology
The study traced causes of death in breast cancer patients diagnosed between 1960 and 1979 and compared them to the general female population using standardized mortality ratios.
Participant Demographics
Breast cancer patients diagnosed between 1960 and 1979.
