110 Breast cancer remains a leading cause of morbidity and mortality among women in Sri Lanka, with significant disparities in diagnosis, treatment, and outcomes compared to more developed nations. Recent research highlights both the advances and the persistent gaps in managing this prevalent disease on the island nation, underscoring the need for improved healthcare infrastructure, awareness, and targeted interventions. The findings were published in the Special Journal of the Medical Academy and Other Life Sciences. Sri Lanka’s healthcare system, supported primarily by the government, provides free medical services to its citizens. Despite this universal access, the quality and availability of cancer care vary significantly across urban, suburban, and rural regions. The majority of cancer diagnoses and treatments are handled by the public health system, which has experienced considerable strain due to an increasing cancer burden. The lack of a national breast cancer screening programme exacerbates the situation, leading to late-stage diagnoses that complicate treatment and reduce survival rates. In Sri Lanka, breast cancer is the most common malignancy among women, with an annual incidence rate of 24.7 per 100,000 women. The country’s National Cancer Institute of Sri Lanka (NCISL) handles around 40% of all cancer patients, making it a critical hub for cancer care. From 2016 to 2020, the NCISL registered 5,181 new cases of breast cancer, with the majority of patients being postmenopausal women. The average age at diagnosis was 56, with the 50–59 age group showing the highest incidence. The demographic profile of breast cancer patients reveals that a significant portion present with advanced disease. Around 66% of the cases are diagnosed at stages I and II, highlighting a potential gap in early detection efforts. Ductal carcinoma remains the most prevalent histological type, accounting for approximately 90% of cases. Moreover, 20% of the diagnosed cases were triple-negative breast cancers, a subtype known for its aggressive nature and limited treatment options. Treatment modalities in Sri Lanka have evolved, yet challenges persist. Surgical interventions are a cornerstone of breast cancer treatment, with 66% of patients undergoing mastectomies. However, the rates of mastectomy and other surgeries differ markedly between early-stage and advanced-stage patients, reflecting the complexities involved in managing advanced cancer. While most patients receive some form of surgery, a significant number also require chemotherapy, radiotherapy, and endocrine therapy. Notably, the availability and quality of these treatments are inconsistent, particularly in rural areas. Radiation therapy and chemotherapy are critical components of the treatment regimen. External radiation therapy is commonly employed, targeting cancerous tissues while sparing healthy cells as much as possible. Chemotherapy, often used in conjunction with surgery or as a standalone treatment, helps shrink tumours and eliminate residual cancer cells. The use of targeted therapies and immunotherapy is emerging, offering new hope for patients with specific cancer profiles, such as HER-2 positive cancers. The research underscores the importance of palliative care and psychosocial support for patients, especially those with advanced disease. Palliative care services, which are currently underdeveloped in Sri Lanka, play a vital role in managing symptoms and improving the quality of life for patients who cannot be cured. Similarly, psychosocial support services, including counselling and support groups, are essential for addressing the emotional and psychological challenges associated with a cancer diagnosis. Future directions for improving breast cancer management in Sri Lanka include the establishment of a comprehensive national cancer control programme. Such a programme would focus on prevention, early detection, equitable access to treatment, and continuous monitoring of patient outcomes. Emphasis on education and awareness is crucial to encourage early diagnosis and reduce risk factors such as unhealthy lifestyles. Moreover, expanding and upgrading healthcare facilities across the country is vital to ensure that all patients, regardless of their location, receive timely and effective treatment.
