India accounts for 70% of South Asia’s childhood leukaemia cases, study highlights urgent need for early diagnosis

A new study published in The Lancet has found that India accounts for nearly 70% of all childhood leukaemia cases in South Asia, underlining the need for stronger healthcare systems, earlier diagnosis and improved access to treatment for children across the country.

The findings show that between 25,000 and 50,000 children below the age of 15 are diagnosed with leukaemia in India every year. Researchers say the country’s large population, combined with gaps in diagnosis and treatment services, has contributed to the high number of reported cases.

Leukaemia is a type of blood cancer that affects the bone marrow and white blood cells. It is one of the most common cancers in children. Doctors say early detection greatly improves the chances of successful treatment, making awareness among parents and caregivers especially important.

The report also points to regional differences in disease burden. In West Bengal alone, an estimated 1,000 to 1,800 new childhood leukaemia cases are recorded annually. Experts believe many cases across the country may still go undiagnosed or receive delayed treatment because of limited access to specialist healthcare, particularly in rural and underserved areas.

Health experts say common warning signs of childhood leukaemia include frequent fever, unusual tiredness, pale skin, unexplained bruising or bleeding, bone or joint pain, swollen lymph nodes and repeated infections. While these symptoms can be linked to several illnesses, persistent signs should be evaluated by a medical professional without delay.

According to researchers, improving access to diagnostic facilities, strengthening paediatric cancer centres and increasing awareness among families and frontline healthcare workers could significantly improve outcomes. Timely referrals and early intervention remain among the most effective ways to reduce complications and increase survival rates.

India has made notable progress in cancer care over the past decade, with several government programmes supporting treatment and expanding healthcare infrastructure. However, specialists believe more investment is needed to ensure children receive equitable access to quality cancer care regardless of where they live.

The study also highlights the importance of reliable cancer registries and better disease surveillance. Accurate data helps policymakers understand the true scale of childhood cancers and plan healthcare resources more effectively.

Medical experts continue to encourage parents not to ignore persistent or unusual symptoms in children. Routine health check-ups, prompt medical consultation and timely investigations can make a critical difference in detecting childhood cancers at an early stage.

Researchers hope the findings will encourage greater collaboration between healthcare providers, policymakers and public health organisations to improve childhood cancer care across India. As awareness grows and access to specialised treatment expands, experts believe more children can receive life-saving care at the right time.

The study serves as an important reminder that while childhood leukaemia remains a major public health challenge, early diagnosis, improved healthcare access and continued investment in paediatric oncology can significantly improve survival and quality of life for thousands of children every year.
