Aims and objectives: Mammography is used in screening for breast cancer world-wide [1], as it offers several advantages as a screening tool, including non-invasiveness, reproducible results, the possibility of early diagnosis and others [2]. However, the detection of abnormalities in the breast and, therefore, the perfo[...]

Methods and materials: In the Norwegian Breast Cancer Screening Program, two radiologists independently read screening mammograms, assessing each breast with a score pertaining to the likelihood of malignancies [9]. About 75% women attend screening after a personal invitation, and 3% of these women are recalled for furthe[...]

Results: The average age of the screened women at time of examination was 60.5 (standard deviation 5.0) years. The mean and median compression force were 119.9 N (standard deviation 16.9) and 120 N, respectively, with range 20.0-237.5 N. Of the 233,673 screening examinations, 5,475 resulted in recall due to [...]

Conclusion: High compression force was associated with higher PPVs compared with low compression force. This might be due to the inverse relationships between compression force and compressed breast thickness [10]. Decreased compressed breast thickness is associated with good fixation of the breast and reductio[...]
