Childhood Cancers

What Are Childhood Cancers?

Childhood cancers are cancers that occur in children and adolescents (0–18 years).

Unlike adult cancers (which are often linked to lifestyle or environmental factors), childhood cancers are usually caused by genetic or developmental changes in cells.

The good news:
✅ Many childhood cancers are highly treatable.
✅ Cure rates are much higher compared to the past.

Most Common Types of Childhood Cancers

🔹 1. Leukemia (Most Common)

Cancer of blood and bone marrow.

🔹 2. Brain and Spinal Cord Tumors

🔹 3. Lymphoma

Hodgkin and Non-Hodgkin lymphoma.

🔹 4. Neuroblastoma

Common in infants and young children.

🔹 5. Wilms Tumor

Kidney cancer in children.

🔹 6. Bone Cancers

Osteosarcoma and Ewing sarcoma.

Common Warning Signs in Children

  • Persistent fever

  • Unexplained weight loss

  • Swelling or lump anywhere in the body

  • Frequent infections

  • Easy bruising or bleeding

  • Persistent headache or vomiting

  • Bone pain or limping

  • White reflection in the eye (in some eye cancers)

⚠️ Symptoms lasting more than 2–3 weeks should be evaluated by a pediatrician.

Causes & Risk Factors

In most cases, the exact cause is unknown.

Possible factors:

  • Genetic mutations

  • Certain inherited syndromes

  • Previous radiation exposure

  • Rare immune system disorders

Childhood cancers are not caused by diet, mobile phones, or minor injuries.

Diagnosis

  • Blood tests

  • Imaging (X-ray, CT, MRI)

  • Bone marrow test

  • Biopsy

  • Genetic testing

Early diagnosis improves outcomes.

Treatment Options

Treatment depends on type and stage:

🔹 Chemotherapy

Main treatment for many childhood cancers.

🔹 Surgery

🔹 Radiation Therapy

🔹 Targeted Therapy

🔹 Immunotherapy

🔹 Bone Marrow / Stem Cell Transplant

Treatment is usually provided by a pediatric oncology team.

Cure Rates

Many childhood cancers have high cure rates:

  • Childhood leukemia: High survival rate

  • Hodgkin lymphoma: Very high cure rate

  • Wilms tumor: Excellent outcomes

With proper treatment, many children grow into healthy adults.
