Study Notes
- Breast cancer is the second leading cause of cancer death in women.
- Screening mammography has decreased breast cancer mortality by 36%.
- Breast density affects mammography sensitivity.
- Screening mammography is recommended for women starting at age 50, with varied frequency and personalized screening for those aged 40-49.
- Digital breast tomosynthesis (DBT) can increase cancer detection rates and decrease false positives.
- DBT is recommended for women under 50, those with dense breasts, and for detecting spiculated masses and asymmetries.
- DBT interpretation time is longer and dose is increased if 2-D images are obtained in addition to DBT images.
- Synthesized reconstructed images may replace the need for a 2-D correlative view.
- Dense breast tissue lowers mammography sensitivity and increases breast cancer risk.
- Screening recommendations should consider life expectancy and comorbid conditions.
