Key Takeaways

  • Childhood cancer refers to abnormal cell growth in children and teens, forming tumors that can spread to other parts of the body
  • Common childhood cancers include leukemia, brain and spinal tumors, lymphoma and kidney tumors. Symptoms may include swelling, persistent pain and unexplained weight loss.
  • Aflac's cancer insurance for individuals and families can help you manage treatment-related expenses by providing added financial support for out-of-pocket expenses.

What is childhood cancer?

Childhood cancer, or pediatric cancer, is abnormal cell growth that affects children and teens. This involves the uncontrollable or atypical growth of cells in the body to form tumors. Some tumors are benign and generally do not spread to other parts of the body, while others are malignant and can spread to nearby tissue and other parts of the body.

Why do children get cancer?

While most cancers in adults have known causes and risk factors, many pediatric cancers do not. However, over the years, researchers have identified some risk factors for cancer in children, including:

  • Inherited genetic factors: Some health conditions may be passed on through their parent's genes. For example, retinoblastoma, a type of eye cancer, may occur in children who inherit a mutated RB1 gene from a parent.2
  • Acquired genetic mutations: Most childhood cancers may be caused by DNA changes that happen before birth (while the fetus is developing) or during the early years of a child's life.3
  • Infections: In some cases, childhood cancers may be linked to chronic infections like HIV, Epstein‐Barr virus and malaria. These infections are particularly relevant in low- and middle-income countries.4
  • Environmental factors: Researchers continue to study the role that environmental exposures may play in childhood cancer. Some studies have identified possible associations between pediatric cancers and exposure to air pollution, pesticides, tobacco exposure and solvents. 5

Types of childhood cancer

Common childhood cancers differ from common adult cancers. Lung and colorectal cancers are more common in adults, along with prostate cancer in men and breast cancer in women.6 Here are some common types of childhood cancers:2

Leukemia

Leukemias, especially acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML), are the most common childhood cancers.

Brain and Spinal tumor

Brain and spinal cord tumors exist in many forms. The treatments and outlook for each can vary. Brain tumors in children may cause headaches, nausea and vision problems, along with other symptoms. In children, most brain tumors start in the lower parts of the brain, such as the cerebellum or brain stem.

Lymphoma

Lymphomas often start in immune system cells and is usually found first in the lymph nodes, tonsils or thymus. They may also affect the bone marrow and other organs over time.

Neuroblastoma

Neuroblastoma is usually observed in infants and young children as it starts in the nerve cells and can sometimes develop before birth.

Kidney tumor

Kidney tumors, sometimes known as Wilms tumors or nephroblastoma, can start in one or both kidneys. It is most often found in children about 3 to 4 years old.

What are some signs of childhood cancer?

Signs and symptoms of childhood cancer depend on the type of cancer and where it starts. Here are some general symptoms that parents and caregivers may want to look out for:7

  • A lump or swelling
  • Easy bruising and bleeding
  • Persistent pain
  • Changes in vision or eyes
  • Sudden weight loss
  • Persistent fevers or illnesses
  • Paleness, fatigue and loss of energy
  • Frequent headaches, changings in vision or speech, and vomiting
  • Balance problems or trouble walking

Can childhood cancer be treated?

Advances in medical science and healthcare have improved treatment outcomes for many forms of childhood cancer. Additionally, long-term survival rates have improved over the past few decades. A multidisciplinary team of medical professionals often tailors the treatment plan to the individual needs of the child, considering factors like:

  • The child's age
  • The child's overall health
  • Anticipated side effects of the treatment

It's also notable that research is ongoing to develop more effective treatments for each type of pediatric cancer.
