Key Takeaways
- In India, childhood cancer makes up about 4% of all cancer cases, with nearly 52,000 children diagnosed each year.
- Globally, nearly 400,000 children (0–14 years) are diagnosed with cancer each year.
- In high-income countries, survival rates are often above 80–90%, but in many low- and middle-income countries, outcomes are still much poorer.
- Strengthening early detection, referral systems, pediatric oncology infrastructure, and survivorship care is essential.
- Global efforts, such as the WHO’s childhood cancer initiative, aim to improve survival rates to at least 60% worldwide by 2030.
Understanding Childhood Cancer: A Global Perspective
Childhood
cancer is an important global health issue that affects families across the world. According to the World Health Organisation, approximately 400,000 children aged 0–14 years are diagnosed with cancer each year worldwide. While more than 85% of children survive in high-income countries, survival can fall to 20–30% in lower-income regions, often because the disease is diagnosed late or treatment is difficult to access.
Unlike adult cancers, pediatric cancers are rarely linked to lifestyle factors such as smoking or diet. Most childhood cancers result from genetic changes that occur early in life. Common types include:
- Leukaemia (most common globally)
- Brain and central nervous system (CNS) tumours
- Lymphomas
- Neuroblastoma
- Wilms tumor
- Bone cancers such as osteosarcoma and Ewing sarcoma
Over the past few decades, new treatments such as advanced chemotherapy, precision radiotherapy, and immunotherapy (including CAR-T therapy) have significantly improved outcomes for many children.
Childhood Cancer in India: Epidemiology and Trends
In India, childhood cancers account for about 4% of all diagnosed cancers, according to the National Cancer Registry Programme (NCRP). Delhi has reported some of the highest incidence rates, while other regions show lower numbers, which may reflect underdiagnosis or limited reporting systems.
Key Indian Data Highlights:
- An estimated 52,000 cases annually (0–14 years)
- Approximately 13,700 childhood cancer deaths were reported in 2010
- Incidence rates have been rising over the past decade.
- Regional disparities in diagnosis and reporting
Leukaemia remains the leading childhood cancer in India, followed by CNS tumours and lymphomas. Social factors and healthcare-seeking patterns may influence differences between boys and girls.
The rising burden is partly due to:
- Improved diagnostic capacity
- Increased cancer awareness
- Population growth
- Better registry reporting
However, the actual number of cases is likely higher in rural and underserved areas where diagnosis may be delayed or missed.
Why Is Childhood Cancer Survival Lower in India?
Even with advances in medicine, several challenges in the healthcare system continue to affect children's outcomes.
1. Delayed Diagnosis
Many children present at advanced stages due to:
- Limited awareness of early warning signs
- Symptoms mimicking common infections
- Delays in referral to specialist centres
- Diagnostic infrastructure gaps in rural areas
Common early symptoms include persistent fever, unexplained weight loss, swelling, bone pain, white pupil reflex, and prolonged fatigue.
2. Financial Toxicity
The economic burden is significant:
- Average treatment cost: ₹1–7 lakh per case
- Around 70% of expenses are out-of-pocket.
- Non-medical costs (travel, accommodation, food) add to the hardship.
- Treatment abandonment rates in some regions have been reported as high as 40–90%
Financial stress often forces families to delay or stop treatment, which directly affects survival.
3. Rural–Urban Access Gap
Nearly 70% of India’s population resides in rural areas, but most pediatric oncology centres are located in urban tertiary hospitals. As a result, families often face:
- Delayed treatment initiation
- Missed follow-ups
- Travel-related financial strain
4. Workforce and Infrastructure Limitations
Pediatric oncology requires specialised multidisciplinary care, including:
- Pediatric oncologists
- Hematologists
- Oncology nurses
- Radiologists
- Social workers
- Nutrition specialists
Workforce shortages and uneven distribution of facilities remain significant barriers.
Government Initiatives and Global Collaborations
India has taken steps to align with global efforts to improve childhood cancer survival.
The World Health Organisation Global Initiative on Childhood Cancer (GICC) aims to achieve at least 60% global survival by 2030. Under this framework:
- The CURE-ALL approach emphasises early diagnosis and comprehensive care
- Strengthening of cancer registries
- Standardisation of treatment protocols
- Improved medicine procurement
Programs such as
Ayushman Bharat provide financial support for eligible families. NGOs like
CanKids and the Indian Childhood Cancer Initiative (ICCI) offer psychosocial support, housing assistance, and awareness campaigns.
However, India does not yet have a separate, dedicated national policy explicitly focused on childhood cancer.
Advances in Pediatric Cancer Treatment
Treatment options for childhood cancer have improved significantly in recent years.
Key Innovations Include:
- Molecular risk stratification in acute lymphoblastic leukaemia (ALL)
- Targeted therapies based on genetic mutations
- Precision radiotherapy to reduce organ damage
- CAR-T cell therapy
- Reduced-intensity treatment protocols for low-risk cases
In high-income countries, five-year survival now exceeds 85–90%. In India, survival rates are improving but remain variable across regions and hospital types.
To improve survival rates further, India needs:
- Improved early detection
- Affordable access to essential medicines
- Strengthened referral systems
- Expanded pediatric oncology training programs
The Importance of Early Diagnosis
Detecting cancer early can make a life-saving difference. When diagnosed at an early stage:
- Treatment is more effective
- Complications are fewer
- Long-term survival increases
- Treatment costs may be lower.
Parents, caregivers, teachers, and primary care providers must be educated about warning signs.
Raising awareness at the community level and strengthening primary healthcare services can help reduce diagnostic delays.
Long-Term Survivorship and Quality of Life
Children who survive cancer may face long-term health challenges, such as:
- Cardiac complications
- Endocrine disorders
- Secondary cancers
- Cognitive challenges
Survivorship programs must include:
- Lifelong monitoring
- Psychosocial counseling
- Nutritional support
- Rehabilitation services
More research on survivorship in India is needed to understand better and address these long-term effects.
The Way Forward: A Collaborative Approach
Improving childhood
cancer care in India will require coordinated efforts at multiple levels:
- Strengthen cancer registries and data accuracy
- Expand regional pediatric oncology centres.
- Improve financial protection mechanisms.
- Invest in workforce training.
- Integrate mental health and supportive care.
- Enhance community education and early referral.
Policymakers, healthcare providers,
researchers, NGOs, and communities must work together to ensure equitable access to high-quality pediatric cancer care.
No child should miss out on life-saving treatment because of where they live, financial hardship, or lack of information.
