In this research, we investigated whether compressed breast thickness (CBT) can be helped by diagnostic stratification factor and we verified the correlation between CBT and other factors. Method: Using 3D imaging MLO mammography we verified 8 items. We categorized 4 groups from 460 cases. The groups range from 20mms to over 50mms, in 10mm increments. Results Discussion: The patient's mean age was 53.8 years, mean compression was 103.5N and mean CBT was 39.7mm. Dense breast rate has a tendency to decline when CBT is large. There is only a low positive correlation between AGD and CBT, likewise BMI and CBT results are positively correlated. As CBT got larger, tumor rates became higher. Rate of both benign and malignant tumors increased. Furthermore, sensitivity of malignant lesions increased after adding a 3D mammography. After a 3D mammography the larger the CBT is, the higher the rate of category change. Compared to CBT 20mm level, CBT 50mm or higher levels showed higher rates of tumors and malignancy. For breasts with smaller CBT it's possible to manually check for tumors at an early stage, however for breasts with larger CBT it becomes difficult to manually check for tumor, which seems likely to delay their finding. Previous research concluded that the risk of developing breast cancer has a tendency to increase in proportion with BMI. In this research CBT increased proportionally with BMI, and the malignancy rates were higher when CBT was large. Among breasts with larger CBT there tends to be a low proportion of dense breast. In addition, the detection sensitivity of malignant tumors was high. Conclusion: According to these results, we believe the risk of breast cancer increases with larger CBT. In summary, there is a higher possibility of early detection of breast cancer by 3D mammography for breasts with larger CBT. It is important to increase breast awareness, and awareness of all available examination, particularly among patients with larger CBT breasts.
