Breast compression in mammography is important in reducing the absorbed dose to the breast and improving the image quality [1][2]. However, many patients experience some degree of discomfort or pain during mammography; some patients even postpone or avoid mammography because of the pain associated with the exam. Previous studies have shown that the perception of discomfort or pain associated with mammography may dissuade women from taking the exam [3][4]. The Mammography Quality Standards Act indicates that “compression shall be between 111 and 200 N” [5]....

Patients After receiving approval from the local institutional review board and obtaining informed written consent, 104 patients aged 28-87(60.4±14.8) coming for bilateral mammography testing between April 2019 and September 2019, who received an explanation about and understood the process of the CCS and agreed to the testing, were included prospectively in the study. The study population was patients referred for diagnostic and screening purposes. Patients with breast implants or who were pregnant, breastfeeding or had had a mastectomy were excluded from the study. The study...

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 

The results of our study show the effectiveness of the CCS in reducing patient’s discomfort and pain regardless of breast composition. The pain increased as the breast volume was reduced in both before and after use of CCS. However, the effect of CCS was greater in the group that experienced more pain before using CCS. The most significant finding was that patients who experienced severe pain levels before using CCS were able to reduce their pain levels by using CCS. In fact, the group which...
