Understanding Cancer in Children: Types, Symptoms, Diagnosis, and Treatment | Expert Guide by Dr. Dhanesh Agrahari

Hearing the word cancer in relation to a child can be overwhelming for any parent. While childhood cancer is relatively rare compared to adult cancers, it remains one of the leading causes of disease-related deaths among children. The encouraging news is that advances in medical science have significantly improved survival rates, especially when cancer is detected and treated early. Unlike adult cancers, childhood cancers are generally not linked to lifestyle choices or environmental factors. They often develop due to changes in cells that occur during a child's growth and development. Recognizing the early warning signs and seeking prompt medical care can make a remarkable difference in treatment outcomes. In this comprehensive guide, Dr. Dhanesh Agrahari, an experienced Pediatric Surgeon, explains the different types of childhood cancers, their symptoms, diagnostic procedures, treatment options, and the importance of early intervention.

What is Childhood Cancer?

Childhood cancer refers to cancers that develop in children and adolescents, typically under the age of 18 years. These cancers are different from adult cancers in terms of their origin, behavior, and treatment. Instead of developing slowly over many years like adult cancers, childhood cancers often grow rapidly. However, they also tend to respond better to chemotherapy and other specialized treatments. Early diagnosis and multidisciplinary care significantly improve the chances of successful treatment.

Common Types of Cancer in Children

Childhood cancers differ significantly from adult cancers, with the most frequent types being leukemias, brain and central nervous system (CNS) tumors, and lymphomas. Unlike adult cancers, which are heavily linked to lifestyle factors, pediatric cancers are mostly unrelated to environment and are usually caused by DNA changes in cells. Several different types of cancers can affect children. The most common include:

1. Leukemia: Leukemia is the most common childhood cancer and affects the blood and bone marrow.

Common Symptoms

• Frequent infections
• Fever
• Fatigue
• Pale skin
• Easy bruising or bleeding
• Bone and joint pain
• Swollen lymph nodes

2. Brain and Spinal Cord Tumors: These tumors affect the central nervous system and are the second most common childhood cancers.

Symptoms

• Persistent headaches
• Morning vomiting
• Balance problems
• Vision changes
• Seizures
• Difficulty walking
• Behavioral changes

3. Lymphoma: Lymphoma affects the lymphatic system and is classified into:

• Hodgkin Lymphoma
• Non-Hodgkin Lymphoma
• Symptoms
• Swollen lymph nodes
• Persistent fever
• Night sweats
• Weight loss
• Fatigue
• Persistent cough

4. Neuroblastoma: Neuroblastoma usually develops in infants and young children and commonly starts in the adrenal glands.

Symptoms

• Abdominal swelling
• Bone pain
• Difficulty walking
• Fever
• Weight loss
• Lump in the abdomen or neck

5. Wilms Tumor: Wilms tumor is a kidney cancer that primarily affects children under five years of age.

Symptoms

• Abdominal swelling
• Blood in urine
• Fever
• High blood pressure
• Loss of appetite

6. Bone Cancers: The two most common bone cancers in children are:

• Osteosarcoma
• Ewing Sarcoma
• Symptoms
• Persistent bone pain
• Swelling around joints
• Difficulty moving limbs
• Bone fractures without major injury

7. Retinoblastoma: Retinoblastoma is a rare eye cancer that usually affects young children.

Symptoms:-

• White reflection in the pupil
• Crossed eyes
• Vision problems
• Eye redness
• Eye swelling
• Early Warning Signs of Childhood Cancer

Many symptoms of childhood cancer resemble common childhood illnesses, making diagnosis challenging. Parents should seek medical evaluation if symptoms persist or worsen.

Common warning signs include:

• Unexplained fever lasting several weeks
• Frequent infections
• Persistent fatigue
• Easy bruising or unusual bleeding
• Persistent bone or joint pain
• Unexplained weight loss
• Swollen lymph nodes
• Persistent headaches
• Repeated vomiting
• Vision changes
• Lump or swelling anywhere on the body
• Difficulty walking
• Persistent abdominal pain or swelling

While these symptoms do not always indicate cancer, they should never be ignored.

What Causes Childhood Cancer?

In most cases, the exact cause of childhood cancer remains unknown.

Possible contributing factors include:

• Genetic mutations
• Certain inherited genetic conditions
• Rare family history of cancer
• Previous radiation exposure
• Some immune system disorders

Unlike many adult cancers, childhood cancers are generally not caused by diet, smoking, or lifestyle habits.

How is Childhood Cancer Diagnosed?

If childhood cancer is suspected, your pediatric specialist may recommend several diagnostic tests.

These may include:

Physical Examination: A detailed medical history and thorough physical examination help identify any concerning signs.

Blood Tests: Blood investigations help detect abnormalities that may indicate leukemia or other cancers.

Imaging Tests

Depending on symptoms, imaging may include:

• Ultrasound
• X-rays
• CT Scan
• MRI Scan
• PET Scan

These tests help determine the size and location of tumors.

Biopsy

• A biopsy involves removing a small tissue sample for microscopic examination.
• This remains the most accurate way to confirm cancer.

Bone Marrow Examination

• For suspected leukemia, a bone marrow aspiration or biopsy helps establish the diagnosis.
• Treatment Options for Childhood Cancer

Treatment depends on:

• Type of cancer
• Stage of disease
• Child's age
• Overall health

Modern pediatric oncology offers highly effective treatment options.

Chemotherapy

• Chemotherapy uses medicines to destroy cancer cells throughout the body.
• It is one of the most commonly used treatments for childhood cancers.

Surgery

• Surgery is performed to remove tumors whenever possible.
• Pediatric surgeons carefully plan procedures to preserve healthy tissues and improve recovery.

Radiation Therapy

• Radiation uses high-energy rays to destroy cancer cells.
• It may be recommended for certain brain tumors, bone cancers, and lymphomas.

Targeted Therapy

These newer medications specifically attack cancer cells while minimizing damage to healthy tissues.

Immunotherapy

• Immunotherapy helps strengthen the body's immune system to fight cancer more effectively.
• This treatment is becoming increasingly important in pediatric oncology.
• Stem Cell or Bone Marrow Transplant
• Children with certain blood cancers may require stem cell transplantation after intensive chemotherapy.

Importance of Early Diagnosis

Early diagnosis offers numerous advantages.

It can:

• Improve survival rates
• Reduce treatment complications
• Allow less aggressive treatment in some cases
• Improve quality of life
• Increase the chances of complete recovery

Parents should never delay consulting a pediatric specialist if symptoms are persistent or unusual.

Can Childhood Cancer Be Prevented?

Unfortunately, most childhood cancers cannot be prevented because their exact causes are unknown.

However, parents can help by:

• Attending regular pediatric checkups
• Monitoring unusual symptoms
• Seeking early medical attention
• Following recommended vaccinations
• Maintaining overall good health

Early recognition remains the best defense.

Supporting a Child During Cancer Treatment: A cancer diagnosis affects the entire family. Emotional and physical support play a vital role in recovery.

Parents can help by:

• Maintaining open communication
• Providing emotional reassurance
• Encouraging healthy nutrition
• Following treatment schedules carefully
• Seeking counseling when needed
• Joining support groups for families facing childhood cancer

Children often cope better when surrounded by love, encouragement, and a strong support system.
