Childhood cancer refers to a range of cancers that occur in children. The most common types of childhood cancers include leukemia, brain tumors, lymphomas, and solid tumors, such as neuroblastoma and Wilms tumor. Unlike adult cancers, the causes of childhood cancers are not strongly linked to lifestyle or environmental factors, but rather to genetic mutations and developmental issues during pregnancy or early life.

Types of Childhood Cancer

Leukemia

Leukemia is the most common type of cancer in children, accounting for about 30% of all childhood cancers. It is a cancer of the blood and bone marrow and is classified mainly into Acute lymphoblastic leukemia (ALL) and Acute myeloid leukemia (AML).

Brain and Central Nervous System Tumors

Brain tumors are the second most common cancers in children. These tumors can occur in various parts of the brain and central nervous system, affecting its function. The most common types include medulloblastoma, glioma, and ependymoma.

Lymphomas

Lymphomas affect the lymphatic system, which is part of the immune system. The two main types of lymphoma are Hodgkin lymphoma (HL) and Non-Hodgkin lymphoma (NHL), with NHL being more common in children.

Solid Tumors

Solid tumors can occur in any organ or tissue, excluding the brain and bone marrow. Notable examples include neuroblastoma, which starts in the adrenal glands, and Wilms tumor, a kidney cancer.

Causes and Risk Factors

The exact causes of childhood cancer are largely unknown. However, some genetic conditions, such as Down syndrome, and prenatal exposure to radiation or certain chemicals, can increase the risk. Most childhood cancers are believed to result from random mutations in the genes of growing cells.

Diagnosis and Treatment

Diagnosis of childhood cancer often involves a combination of blood tests, imaging tests (such as MRI or CT scans), and biopsies. Treatment varies by the type and stage of cancer and may include chemotherapy, radiation therapy, surgery, and stem cell transplant.

Prognosis

The prognosis for childhood cancer has improved significantly over the past few decades, with the overall five-year survival rate now exceeding 80%. However, survival rates vary widely depending on the type of cancer and its stage at diagnosis. Long-term side effects of treatment, including secondary cancers, heart and lung problems, and growth and developmental delays, are concerns for survivors.

Research and Support

Ongoing research aims to improve the understanding, diagnosis, and treatment of childhood cancers. Support for affected families is available through various non-profit organizations and support groups, which provide resources, counseling, and assistance with navigating the healthcare system.
