What is Pediatric Cancer?
Pediatric cancer refers to any cancer that develops in a child or adolescent, usually defined as under the age of 18. Unlike adult cancers, which most often arise in organs after years of cumulative damage, most childhood cancers develop in fast-growing tissues — the blood, lymph nodes, brain, kidneys, bones — and have very different biology, behaviour, and treatment from adult cancers. This is why children with cancer should be treated at centres with dedicated paediatric oncology expertise.
Across India, around 50,000 children are diagnosed with cancer every year. The good news is that survival has improved dramatically over the last three decades, with modern multimodal treatment achieving cure rates of 80% or more for many common childhood cancers. The most important factors in outcome are early diagnosis, treatment at a specialist centre, and the family's ability to complete the full course of treatment — which is precisely why a network of accessible, multidisciplinary paediatric cancer care matters so much.
Common Signs & Symptoms of Pediatric Cancer
Many childhood cancer symptoms overlap with common, harmless childhood illnesses — which is precisely why they are so easy to miss. Watch for persistent symptoms that do not respond to standard treatment within 2–3 weeks:
- A persistent unexplained fever lasting more than 2 weeks
- Pale skin, unusual tiredness, or weakness that does not improve
- Easy bruising, unexplained bleeding, or tiny red spots on the skin (petechiae)
- A persistent painless lump or swelling — in the abdomen, neck, armpit, groin or anywhere else
- Persistent bone or joint pain, especially if it wakes the child at night
- Unexplained weight loss, loss of appetite, or poor growth
- Persistent headaches, especially with morning vomiting or unusual drowsiness
- New squint, vision changes, or a white reflection from the pupil in flash photographs
- Recurrent infections that take longer than usual to clear
- A noticeable change in the child's behaviour, energy or play
Did you know? More than 70% of children with cancer in India can be cured today.
With modern multimodal treatment, cure rates of 80% or more are now achievable for the most common childhood cancers — including over 85% for acute lymphoblastic leukaemia and over 95% for early-stage retinoblastoma. The two biggest factors in outcome are early diagnosis and completing the full course of treatment without interruption.

Every Childhood Cancer Journey Begins With a Single Step
Tumor-board led, evidence-based paediatric cancer care — guided by NCCN, COG and SIOP protocols, supported by Aarogyasri and EMI options.
Types of Pediatric Cancer
Cancer in children is not one disease. Several distinct cancers occur, each with its own typical age group, symptoms and treatment. The most common include:
Leukaemia (Blood Cancer)
The most common childhood cancer. Acute lymphoblastic leukaemia (ALL) is most frequent and primarily affects children aged 2–5, while acute myeloid leukaemia (AML) can occur at any age. Treatment is intensive chemotherapy, sometimes combined with targeted therapy or bone marrow transplant. Cure rates for childhood ALL today exceed 85%.
Brain and Central Nervous System Tumours
The second most common group. Includes medulloblastoma, gliomas, ependymomas and craniopharyngiomas. Treatment combines surgery, chemotherapy and radiation, with outcomes varying widely by type and location.
Lymphomas
Cancers of the lymphatic system — Hodgkin lymphoma in older children and adolescents, and non-Hodgkin lymphoma at any age. Both have very high cure rates with modern chemotherapy and, where needed, radiation.
Neuroblastoma
A cancer of immature nerve cells, almost always in children under 5. It typically presents as a lump in the abdomen, neck or chest. Treatment is risk-stratified — low-risk neuroblastoma often needs little more than observation or surgery, while high-risk disease requires intensive multimodal therapy.
Wilms Tumour (Nephroblastoma)
A kidney cancer that primarily affects children under 5. Typically presents as a painless abdominal lump found during bathing or routine examination. With modern combination chemotherapy and surgery, cure rates exceed 90%.
Bone Cancers (Osteosarcoma & Ewing Sarcoma)
Primary bone cancers seen most often in older children, teenagers and young adults. Modern treatment combines chemotherapy with limb-sparing surgery and, in Ewing sarcoma, often radiation. Cure rates for localised disease are 60–75%.
Retinoblastoma
A rare eye cancer of young children, often noticed when a parent sees a white reflection from the pupil in flash photographs. Early diagnosis can save the eye and the child's life — modern treatment cures over 95% when diagnosed early.
Soft Tissue Sarcomas
A group of cancers of muscle, fat and connective tissue, with rhabdomyosarcoma being the most common in children. Treated with a combination of chemotherapy, surgery and radiation.

Pediatric Cancer in Telangana & Andhra Pradesh
Around 50,000 children in India are diagnosed with cancer every year, and Telangana and Andhra Pradesh contribute a meaningful share. Outcomes for childhood cancer in India have improved enormously over the last two decades — with modern protocols, cure rates of 80% or more are now achievable for the most common childhood cancers. The two biggest determinants of outcome remain early diagnosis and the ability to complete the full course of treatment without interruption.
Across the region, common barriers include delayed referral from primary-care settings, financial worries that lead families to discontinue treatment, and limited awareness of childhood cancer warning signs. Aarogyasri coverage, EMI options and dedicated paediatric oncology services have made specialist care more accessible than ever — any child with persistent unexplained symptoms deserves a specialist opinion without delay.
Did you know? Childhood acute lymphoblastic leukaemia cure rates exceed 85%.
ALL is the most common childhood cancer — and one of medicine's biggest success stories. With modern risk-stratified protocols, more than 85% of children with ALL are cured today, compared with under 30% in the 1970s. Completing the full course of treatment, which can take 2–3 years, is the single biggest factor in cure.
Cure Rates for Common Childhood Cancers
Modern multimodal treatment has transformed paediatric cancer outcomes over the last three decades. Cure rates below reflect children diagnosed early and treated to protocol completion at a specialist centre.
| Childhood Cancer | Modern Cure Rate* | Notes |
|---|---|---|
| Acute Lymphoblastic Leukaemia (ALL) | > 85% | Risk-stratified chemotherapy ± targeted therapy |
| Hodgkin Lymphoma | > 90% | Combination chemotherapy ± radiation |
| Wilms Tumour (Nephroblastoma) | > 90% | Surgery + combination chemotherapy |
| Retinoblastoma (early-stage) | > 95% | Eye-sparing modern treatment |
| Bone Cancers (localised) | 60–75% | Chemotherapy + limb-sparing surgery |
*Cure rates are long-term survival figures from published international cooperative-group trials (COG, SIOP). Outcomes for individual children depend on stage, biology, and timely completion of treatment. Source: published paediatric oncology cooperative-group protocols.
Common Causes & Risk Factors
The cause of childhood cancer is usually not identifiable — most cases occur in healthy children with no obvious risk factors. Known associations include:
- Inherited cancer syndromes such as Li-Fraumeni syndrome, hereditary retinoblastoma, neurofibromatosis, Down syndrome and Beckwith-Wiedemann syndrome
- Previous radiation therapy or chemotherapy for an earlier cancer
- Certain congenital immune deficiency disorders
- In-utero exposure to ionising radiation (rare)
- A family history of certain childhood cancers (occasional)
When to See a Pediatric Cancer Specialist
Any of the following should prompt a paediatric specialist or oncology evaluation:
- Unexplained fever lasting more than 2 weeks despite treatment
- Persistent pallor, easy bruising, bleeding, or tiny red spots on the skin
- Any painless lump or swelling in a child that has lasted more than 2 weeks
- Bone or joint pain that wakes the child from sleep
- Persistent morning headaches with vomiting or unusual drowsiness
- A new squint, vision change, or a white pupil reflection in photographs
- Unexplained weight loss, persistent loss of appetite, or failure to grow
- Any abnormality found on a routine examination, ultrasound or blood test
A short specialist consultation and the right diagnostic test — imaging, endoscopy, biopsy, or blood test as appropriate — is usually enough to confirm or rule out cancer. Early action is always easier than catching up later.

What are the first signs of cancer in children?
The most common first signs are a persistent unexplained fever, unusual pallor or tiredness, easy bruising or bleeding, a painless lump or swelling, persistent bone or joint pain (especially at night), persistent morning headaches with vomiting, unexplained weight loss, or a new squint or white reflection from the pupil. The key warning is persistence — any symptom lasting more than 2 weeks without clear improvement deserves a specialist opinion rather than further over-the-counter treatment.
Is childhood cancer curable?
Yes — childhood cancer is more curable than most parents realise. With modern multimodal treatment, cure rates of 80% or more are achievable for the most common childhood cancers, including acute lymphoblastic leukaemia (over 85% cured), Hodgkin lymphoma (over 90% cured), Wilms tumour (over 90% cured), and early-stage retinoblastoma (over 95% cured). The two biggest factors in outcome are early diagnosis and completing the full course of treatment without interruption.
Which is the most common cancer in children?
Leukaemia — particularly acute lymphoblastic leukaemia (ALL) — is the most common childhood cancer, accounting for around 25–30% of all paediatric cancer cases. Brain and central nervous system tumours are second, followed by lymphomas, neuroblastoma, Wilms tumour, bone cancers (osteosarcoma and Ewing sarcoma), retinoblastoma, and soft tissue sarcomas.
What causes cancer in children?
The cause is usually not identifiable. Unlike adult cancers, which are often linked to lifestyle and environmental factors, childhood cancers are generally not caused by anything the child or family did. A small minority of cases are linked to inherited cancer syndromes (Li-Fraumeni, hereditary retinoblastoma, neurofibromatosis) or specific genetic conditions like Down syndrome. Previous radiation or chemotherapy for an earlier cancer is another known risk factor.
Can my child receive treatment at CION even if we can't afford private care?
Yes. CION Cancer Clinics is empanelled with the Aarogyasri Health Care Trust, providing cashless treatment for eligible Telangana residents. EMI options are available for all families, and our team helps with insurance approvals and structured financial planning. Completing the full course of treatment is the single biggest factor in cure — and we work hard to remove cost as a reason for treatment interruption.
