Season of Detection of Breast Cancer
Author Information
Author(s): Barbara Mason, Ian Holdaway
Primary Institution: University of Auckland
Hypothesis
Does the season of detection of breast cancer affect patient survival?
Conclusion
The season of tumor detection is a significant prognostic variable, but its influence on treatment results or prognosis is likely minor compared to other factors.
Supporting Evidence
- An increase in breast tumor detection in spring/summer is documented in seven published papers.
- The study acknowledged the independence of known prognostic variables in breast cancer.
Takeaway
This study suggests that when women find their breast cancer in spring or summer, it might not change their chances of survival much compared to other important factors.
Methodology
Proportional hazards regression analysis was used to assess the significance of the season of tumor detection.
Potential Biases
The data may not include all cases of breast cancer in the studied area.
Limitations
The study may not represent all geographic regions, and there was no mammography screening during the data collection period.
Participant Demographics
The study included all cases over 9 years from one geographic region.
