Singapore’s Breast Cancer Story: A Tale of Rising Cases, Falling Deaths
Singapore is experiencing a complex trend in breast cancer: while the number of cases is increasing, the number of deaths is declining. New research, published in The Lancet Oncology and analyzed by the Global Burden of Disease (GBD) study, reveals a 50% rise in breast cancer incidence in the Republic between 1990 and 2023 – from 41.58 to 62.33 cases per 100,000 women. However, over the same period, the mortality rate fell by 23.4% to 12.47 deaths per 100,000 women, a figure lower than the global average of 16.14.
The Global Picture: A Looming Crisis
The Singaporean success story stands in stark contrast to the global outlook. The GBD study projects a one-third increase in global breast cancer cases, rising from 2.3 million in 2023 to over 3.5 million by 2050. Annual deaths are expected to nearly double, climbing from 764,000 in 2023 to approximately 1.4 million in 2050. Lower-resource countries are predicted to bear the brunt of this increase, facing challenges in early detection, treatment access, and overall healthcare infrastructure.
Why the Discrepancy? Early Detection and Improved Treatment
According to Associate Professor Marie Ng from the NUS Yong Loo Lin School of Medicine, the key to Singapore’s positive trend lies in earlier diagnoses and improved treatment. Over 57% of breast cancer cases in Singapore are now detected at Stage 1, significantly improving prognosis and survival rates. This is coupled with advancements in treatment protocols and increased access to care.
“Once you’re diagnosed at Stage 1, your prognosis is much better,” explains Prof Ng.
Factors Contributing to Rising Incidence
Despite the success in lowering mortality, the increase in breast cancer cases is linked to several factors. Greater longevity – as cancer risks increase with age – plays a role. Rising rates of diabetes and obesity, and trends towards later pregnancies and fewer births, may also contribute to the increase in incidence.
Modifiable Risk Factors: What Can We Change?
The GBD study identified several modifiable risk factors linked to breast cancer. High red meat consumption was found to be associated with almost 11% of all healthy life lost. Other significant factors include tobacco use, high body mass index, high blood sugar, high alcohol use, and low physical activity. While progress has been made in reducing the impact of tobacco and alcohol, other risk factors haven’t shown the same improvement.
Did you recognize? Almost four in ten cancer cases worldwide in 2022 were linked to preventable causes, according to the World Health Organization.
Singapore’s Proactive Approach
Singapore is actively working to maintain its positive trajectory. Health Minister Ong Ye Kung recently announced expanded subsidies for genetic testing for hereditary breast and ovarian cancer, associated with mutations in genes like BRCA1 or 2. Combined with existing subsidies for breast cancer screening, access to early detection is becoming increasingly available.
Pro Tip: Don’t delay. Seize advantage of available screening services and discuss your individual risk factors with your doctor.
The Path Forward: Prevention, Detection, and Access
Experts emphasize the importance of a multi-pronged approach to combatting breast cancer. Dr. Alicia Ong, an adjunct lecturer at NUS Medicine, stresses that “prevention, early detection and access to care must go hand in hand.” Effective public health policies and promoting healthier lifestyle choices are crucial, alongside ensuring equitable access to screening and treatment.
Frequently Asked Questions
- Is breast cancer becoming more common? Yes, globally, breast cancer cases are projected to rise significantly. However, Singapore is seeing a decline in mortality rates despite increasing cases.
- What are the main risk factors for breast cancer? Factors include age, genetics, lifestyle choices (diet, exercise, alcohol consumption), and reproductive history.
- Can breast cancer be prevented? While not all cases are preventable, adopting a healthy lifestyle and participating in regular screenings can significantly reduce risk and improve outcomes.
- What is the role of genetic testing? Genetic testing can identify individuals with a higher risk due to inherited gene mutations, allowing for more proactive monitoring and preventative measures.
