AI in Breast Cancer Screening at Tan Tock Seng Hospital
Tan Tock Seng Hospital in Singapore is piloting the use of artificial intelligence (AI) in breast cancer screening to improve detection rates and provide faster, more accurate results. This involves integrating AI with existing technologies like mammography, ultrasound, and tomosynthesis. The goal is to assist radiologists in detecting subtle abnormalities and prioritizing urgent cases.
Breast Cancer Screening Rates in Singapore
Breast cancer is the most common cancer among women in Singapore, affecting one in 13 women. However, screening rates are lower compared to other developed nations. Only about 3 in 10 Singaporean women aged 50-69 have undergone breast cancer screening in the past few years, compared to rates as high as 8 in 10 in countries like Denmark.
Barriers to Screening and the Singapore Cancer Society's Approach
The Singapore Cancer Society views low screening rates as a reflection of human experiences and concerns, not simply medical noncompliance. Barriers include:
- Cost of treatment
- Discomfort associated with the procedure
- Time constraints
- Life circumstances
- Stigma
- Misconceptions about screening (e.g., only for those with symptoms)
The Singapore Cancer Society aims to create supportive spaces where people feel heard and empowered to make informed screening decisions. They focus on addressing the lived realities of women in Singapore and transforming screening from a clinical obligation into personalized healthcare.
Importance of Early Detection
Early detection of breast cancer significantly improves survival rates. Singapore data shows that nearly three-quarters of cases detected are at the earliest, most treatable stages. The 5-year survival rate can exceed 90% for early-stage breast cancer detected through screening. Early detection enables more effective, less aggressive treatment and improves long-term quality of life.
Initiatives to Improve Screening Access
The Singapore Cancer Society complements the Healthier SG initiative by making mammograms accessible at no cost to eligible individuals. They also partner with the National Healthcare Group Diagnostics and Breast Cancer Foundation to run the Community Mammogram Programme (BRISK), bringing breast screenings to women in the community.
Technological Advances in Screening
Technological advances like digital mammography have made screening more accurate and faster, reducing recall rates and improving the detection of smaller cancers, especially in women with dense breast tissue. AI is increasingly being integrated to assist radiologists in detecting subtle abnormalities, flagging suspicious lesions, and prioritizing cases.
Acceptability of New Technologies
The success of sophisticated screening technology depends on its acceptability within the framework of knowledge that addresses fundamental human behaviors and concerns. It's crucial to assess how women adopt these screening advances amidst their busy lifestyles and address concerns like procedural discomfort.
Advice for Breast Health and Early Detection
Dr. Priyankara Jendrarom advises women to maintain a healthy lifestyle and go for regular screenings. She also emphasizes the importance of self-breast examination for both men and women to be aware of changes like lumps, skin changes, nipple changes, or unusual discharge. Prompt medical attention should be sought if any of these are noticed. Family support plays a crucial role in encouraging loved ones to go for screening.
Conclusion
The integration of AI into breast cancer screening holds promise for faster and more accurate detection, potentially encouraging more women to get screened. However, addressing the underlying human factors and concerns that influence healthcare decisions is crucial for improving screening rates and ultimately saving lives. The Singapore Cancer Society's efforts to provide accessible screenings, address misconceptions, and foster supportive environments are vital in this endeavor.
