- Mammography:
- Bilateral, comparative examination
- Low-dose film/screen technique that delivers as little as
0,1 cGy per study
- Rarely efficient before 30 y
- Because of screening programs 10-15% of mammography
detected breast cancers can not be detected clinically.
- Sensibility and specificity:
- Sensibility and specificity that exceeds 90%
- Low specificity (25%) in patients whose breast cancer can
not be detected clinically
- Accuracy significantly greater than clinical
examination for detection of occult or early tumors.
- Image suggestive of malignancy:
- Spiculated or irregular margins
- Fine, stippled calcium or calcification of the lesion
- Architectural distortions, duct dilatation, asymmetry and
fibronodular densities
- Accuracy significantly greater than clinical
examination for detection of occult or early tumors.
