Results
Assessment of pain level before and after using CCS
The mean compression force was 139.8 N (±2.90) for the first compression and 81.2 N (±4.56) for CCS. The change in CBT resulted in 0% at 1mm, 14% at 2mm, 82% at 3mm, and 4% at 4mm. The median [interquartile range] pain scores were 8 [5, 9] and 5 [4, 7] before and after using CCS, respectively, which showed a significant difference (p <0.01) (Fig.2.3). Pain levels were statistically and significantly lower after use of CCS compared with prior use of CCS.
Correlation between breast volume and CCS effectiveness
Figure.4 details the correlation between pain and breast volume in both before and after using CCS. There were significant differences between mild and severe (P<0.01), moderate and severe (P<0.01) in both before and after using CCS. The pain increased as the breast volume was reduced in both before and after use of CCS.
Figure.5 shows pain levels experienced 140N (before using CCS) and pain reduction using the CCS (ΔNRS). There were significant differences between mild and moderate (P<0.01), mild and severe (P<0.01), moderate and severe(P<0.05). The impact of CCS was greater in the group that experienced more pain before using CCS.
Correlation between breast composition and CCS effectiveness
Figure.6 shows the correlation between breast composition and pain reduction using the CCS (ΔNRS).
There was no correlation between breast composition and CCS effectiveness.
Patient’s evaluation of using CCS mammography experience
According to the patients’ questionnaires, 73% of patients reported that CCS would motivate them to return for future examinations with CCS, whereas 22% reported that they would return either way, and 5% reported that they would not come back regardless of the CCS (Fig.7).
