Understanding Childhood Cancer

Cancer is a formidable adversary that knows no age boundaries. When it strikes infants, children, and adolescents, it presents a distinct set of challenges that require specialised care, unwavering support, and a deep understanding of the unique needs of young patients.

Infants: The Silent Strugglers

Cancer in infants is rare but presents unique challenges when it occurs. Diagnosing cancer in infants can be intricate due to limited communication and subtle symptoms. Moreover, their delicate physiology necessitates cautious treatment approaches that minimise potential long-term effects on growth and development.

Children: A Balance of Healing and Normalcy

For children, the battle against cancer often intersects with crucial developmental milestones. Balancing aggressive treatments with maintaining a semblance of everyday childhood experiences becomes a critical challenge. Pediatric oncologists work closely with multidisciplinary teams to design treatment plans that address the disease while preserving the child's well-being.

Adolescents: Navigating Identity and Independence

Cancer during adolescence comes at a time of self-discovery and burgeoning independence. Young patients may grapple with unique emotional and social challenges as they strive to maintain their identity while facing a life-altering diagnosis. Providing age-appropriate information, involving them in treatment decisions, and fostering peer connections are crucial aspects of care.

Types of Cancers in Infants, Children, and Adolescents:

Leukaemia

Leukemia is the most common type of pediatric cancer. It affects the bone marrow and blood, producing abnormal white blood cells. Acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) are two common subtypes.

Brain and Central Nervous System Tumors

Brain tumors can occur in various parts of the brain and spinal cord.

Neuroblastoma

This cancer typically begins in the adrenal glands but can also develop in nerve tissue along the spine, chest, abdomen, or pelvis. It most often affects infants and young children.

Wilms Tumor

A kidney cancer that primarily affects children, usually before age five. It often presents as a swelling or lump in the abdomen.

Lymphoma

Cancer of the lymphatic system. Lymphomas can develop in lymph nodes or other lymphatic tissues.

Bone Cancers

Osteosarcoma and Ewing sarcoma are the primary types of bone cancers in children and adolescents. These cancers often develop in the bones of the arms, legs, or pelvis.

Rhabdomyosarcoma

This cancer originates in soft tissues, such as muscles. It can occur in various body parts and is more common in children.

Retinoblastoma

A rare eye cancer that develops in the retina. It primarily affects infants and young children.

Importance of Timely Diagnosis: Diagnostic Methods for Childhood Cancers

Physical Examination

Provides healthcare professionals with valuable insights into a child's health. Any unusual symptoms, family history of cancer, or changes in growth patterns are carefully evaluated.

Laboratory Tests

Blood and urine tests can reveal abnormal cell counts, markers, and substances that may indicate the presence of cancer.

Imaging Techniques

Various imaging tools are employed to visualise internal structures and identify abnormalities. X-rays, ultrasounds, computed tomography (CT) scans, magnetic resonance imaging (MRI), and positron emission tomography (PET) scans help assess tumour size, location, and potential spread.

Biopsy

It involves removing a small tissue sample for examination. It provides crucial information about the type of cancer, its aggressiveness, and potential treatment approaches.

Bone Marrow Aspiration and Biopsy

These tests help identify the presence of cancer cells in the bone marrow and aid in diagnosing diseases like leukemia.

Cytogenetic and Molecular Testing

These tests analyze genetic and molecular changes in cancer cells. They provide insights into the cancer's specific characteristics and guide treatment decisions.

Lumbar Puncture (Spinal Tap)

This procedure involves collecting cerebrospinal fluid from the spinal cord to detect the presence of cancer cells in the central nervous system.

Multidisciplinary Approach: A Collaborative Effort

Diagnosing childhood cancers often requires a multidisciplinary approach. Pediatric oncologists collaborate with radiologists, pathologists, hematologists, and other specialists to interpret diagnostic findings accurately and formulate comprehensive treatment plans.

Promise of Precision Medicine: Tailoring Treatment to the Individual

Advancements in diagnostic tools have paved the way for precision medicine, where treatment is tailored to the specific characteristics of a child's cancer. Molecular profiling and genetic testing enable healthcare professionals to identify targeted therapies that have the potential to be more effective and less harmful than traditional treatments.

Treatment Options for Childhood Cancers

Surgery

Involves the removal of cancerous tissue or tumors. It is often used to diagnose, stage, and remove localised tumors. Minimally invasive techniques aim to reduce the impact on the child's body.

Chemotherapy

Uses powerful drugs to destroy or inhibit the growth of cancer cells. It may be administered orally, intravenously, or directly into the spinal fluid. Chemotherapy is a systemic treatment that can reach cancer cells throughout the body.

Radiation Therapy

Employs high-energy beams to target and destroy cancer cells. It may be used before or after surgery or in combination with chemotherapy.

Stem Cell Transplantation

Involves replacing damaged bone marrow with healthy stem cells. It is commonly used to treat certain blood-related cancers like leukemia and lymphoma.

Immunotherapy

Harnesses the body's immune system to recognize and attack cancer cells. It includes treatments like monoclonal antibodies and checkpoint inhibitors.

Targeted Therapy

Focuses on specific molecules involved in the growth of cancer cells. These treatments are tailored to the genetic and molecular characteristics of the cancer.

Precision Medicine

Uses genetic and molecular profiling to identify personalised treatment options that are more effective and less toxic for each child.

Supportive Care

Measures, including pain management, nutrition support, and psychological counselling, are crucial in improving the quality of life during and after treatment.

Conclusion

Learning about pediatric cancers gives us the power to make a difference. When we know the facts, we can help find these cancers early, support families, and promote research. Knowledge becomes a shield against the unknown. Pediatric cancers don't just affect the child; they impact the whole family. Families come together, showing love and strength and helping each other through tough times. Their support creates a positive environment where young patients can heal.
