Summary
Digital breast tomosynthesis (DBT) shows promise for breast cancer screening, potentially improving cancer detection and reducing callbacks. Annual screening remains crucial for reducing breast cancer mortality, though further research is needed on DBT
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Mammography screening reduces breast cancer mortality but faces controversial recommendations.
- Digital breast tomosynthesis (DBT) is an emerging technology poised to become a standard in breast cancer screening.
Purpose of the Study:
- To present evidence-based recommendations for breast cancer screening.
- To compare the efficacy of digital mammography alone versus digital mammography with DBT.
Main Methods:
- A PubMed literature review was conducted.
- Five large clinical studies comparing digital mammography with and without DBT were examined.
Main Results:
- Digital breast tomosynthesis (DBT) increases cancer detection rates.
- DBT also reduces the number of callbacks for further imaging.
- Annual screening is emphasized for reducing breast cancer mortality.
Conclusions:
- DBT may enhance breast cancer screening effectiveness by improving detection and reducing false positives.
- Further research is necessary to confirm if increased detection rates with DBT translate to reduced mortality.
