Hypothesis
What factors determine the number of mammography units in countries with significant mammography screening?
Conclusion
There is considerable variation in the density of mammography units across countries, often exceeding local screening recommendations.
Supporting Evidence
- Countries with more radiologists tend to have more mammography units.
- Some countries have a high number of mammography units compared to the number of women needing screening.
- High density of mammography units may lead to unnecessary screenings.
Takeaway
This study looked at how many mammography machines are in different countries and found that some have way more than they actually need.
Methodology
Data on mammography units and radiologists were collected from institutions in 34 countries through direct contact and literature review.
Potential Biases
Potential bias in data collection due to reliance on self-reported information from institutions.
Limitations
Data on the number of mammography units were not available for three countries, and data on radiologists were missing for seven countries.
Participant Demographics
Data were collected from 31 countries across Europe, North America, and Asia.
