When we imagine childhood, we think of laughter, innocence, and endless energy. But for some families, unexpected health challenges can cloud those precious years. One such specialised medical area that often goes unnoticed is Paediatric Haematology—the science of diagnosing and treating blood disorders in children.

Let’s explore what it means, why it matters, and how parents can recognise when to seek expert help.

What is Paediatric Haematology?

Paediatric Haematology is a medical subspecialty that focuses on blood-related disorders in children, ranging from infancy to adolescence. It includes both benign (non-cancerous) and malignant (cancerous) blood conditions such as:

• Leukaemia (blood cancers)
• Anaemia (especially iron deficiency)
• Thalassemia
• Sickle Cell Disease
• Haemophilia and clotting disorders

While many associate haematology with cancer, it encompasses a much broader spectrum—covering the entire circulatory and blood-forming system.

Blood Disorders in Children – More Than Just Cancer

Most parents are surprised to learn that blood is considered an organ. And like any organ, it can malfunction. Though cancer is a major concern, several non-cancerous blood disorders are common in Indian children, especially in specific regions.

🔍 Common Paediatric Blood Disorders:

• Leukaemia – Acute Lymphoblastic Leukaemia (ALL), Acute Myeloid Leukaemia (AML), and Chronic Myeloid Leukaemia (CML)
• Thalassemia – A hereditary condition affecting haemoglobin production
• Sickle Cell Anaemia – Prevalent in regions like Wayanad
• Iron Deficiency Anaemia – A widespread issue due to poor nutrition
• Haemophilia – A genetic disorder that impairs the blood’s ability to clot

Who Needs a Paediatric Haematologist?

Children of all age groups—from newborns to teens—can be affected by blood disorders. In some rare cases, even in-utero diagnosis (while still in the womb) is possible for genetic blood conditions. Most paediatric haematologists treat children up to the age of 21, depending on the country’s guidelines.

Age-specific trends in paediatric blood diseases:

• Infants and toddlers: Leukemia, Wilms Tumor (Kidney), Neuroblastoma
• Young children: Thalassemia, Iron deficiency, Immune disorders
• Adolescents: Bone cancers like Osteosarcoma, Germ cell tumours

How Childhood Cancers Differ from Adult Cancers

Unlike adults, children rarely develop cancers of the lungs, breasts, or colon. Instead, blood cancers and brain tumours are more common in kids. Pediatric cancers also tend to grow faster—but respond better to treatment in many cases.

A few notable paediatric cancers include:

• Leukemias – The most common childhood cancer
• Brain tumours
• Wilms Tumour – A kidney tumour common in younger children
• Neuroblastoma – Arising from adrenal glands
• Osteosarcoma – A bone tumour in teenagers
• Germ Cell Tumours – Found in the reproductive organs

The Importance of Awareness and Early Diagnosis

Early symptoms of paediatric haematological disorders often mimic common childhood illnesses—fatigue, paleness, bone pain, or frequent infections. But ignoring persistent symptoms can delay diagnosis.

That’s why awareness among parents, paediatricians, and caregivers is vital. With timely intervention, most of these conditions—both benign and malignant—are treatable and manageable.

Paediatric Haematology is a lifeline for many children fighting invisible battles. As parents, staying informed and trusting your instincts is crucial. If your child exhibits ongoing signs of fatigue, bleeding, or infections, don’t wait—seek a paediatric nematologist.
