Evaluation of Breast Cancer Screening Services Using Mammograms and Ultrasounds via Mobile Mammography Units

Abstract

Objective: Breast cancer is a major public health concern in Thailand, ranking as the most common cancer among Thai women, with an annual incidence of 17,043 cases and 4,753 deaths. Proactive screening methods, such as breast self-examination (BSE), clinical breast examination (CBE), mammograms, and ultrasounds, are crucial in reducing mortality rates. However, access to these technologies remains limited, particularly in remote areas, due to insufficient mammography machines nationwide. This study aims to evaluate breast cancer screening outcomes among at-risk populations and improve access to medical services in underserved areas.

Materials and Methods: This retrospective study analyzed data from 525 women aged 14-82 who underwent mammograms and ultrasounds via mobile screening units between April and August 2024.

Results: The results showed that 121 participants (23.05%) presented abnormalities requiring follow-up, classified under BIRADS 3–5 risk categories. The estimated number of breast cancer cases from this study is higher than the national average incidence rate.

Conclusion: The findings highlight the effectiveness of mobile screening units in detecting abnormalities and increasing access to services in underserved areas. The incidence of breast cancer in the population studied was approximately 20.02-31.34 per 1,000 individuals. The research underscores the need to expand access to advanced screening technologies and consider extending mammogram and ultrasound benefits to high-risk populations. Further cost-effectiveness and long-term outcomes studies are recommended to support policy development and enhance national breast cancer screening strategies.
