There are many different types of cancer that can affect children, but some of the most common types include:

Leukemia: Leukemia is a cancer of the blood and bone marrow. It is the most common cancer in children and adolescents, accounting for about one-third of all pediatric cancers. There are several subtypes of leukemia, including acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML).

Brain and spinal cord tumors: Brain and spinal cord tumors are the second most common type of cancer in children, accounting for about 20% of pediatric cancer cases. These tumors can be benign (non-cancerous) or malignant (cancerous) and can occur anywhere in the brain or spinal cord.

Lymphoma: Lymphoma is a cancer that develops in the lymphatic system, which is part of the immune system. Lymphomas can be Hodgkin lymphoma or non-Hodgkin lymphoma.

Neuroblastoma: Neuroblastoma is a type of cancer that develops in the nerve cells and usually develops in the adrenal glands, but it can also be found in other parts of the body. This type of cancer is most commonly found in young children.

Rhabdomyosarcoma: Rhabdomyosarcoma is a type of cancer that develops in the muscles, usually in the head and neck, genitourinary tract, and in the extremities. This type of cancer is most commonly found in young children.

Retinoblastoma: Retinoblastoma is a type of cancer that develops in the eye, most commonly in children before the age of five.

Wilms tumor: Wilms tumor is a type of kidney cancer that occurs in children, typically before the age of 5.

There are other cancers as well that happen to children and adolescents, but these are the most common ones. Each type of cancer is unique and has its own set of signs and symptoms, as well as treatment options. It’s important to consult with a pediatric oncologist, if your child is diagnosed with cancer, to determine the best course of treatment.

Here is a bit more information on some of the most common types of cancer in children:

Leukemia: Leukemia is a cancer of the blood and bone marrow. It starts in the cells that develop into white blood cells, which are an important part of the body’s immune system. There are two main types of leukemia: acute and chronic. Acute leukemia progresses quickly and requires immediate treatment, while chronic leukemia progresses slowly and may not require immediate treatment. The two main types of acute leukemia are acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). ALL is more common in children, while AML is more common in adults. Symptoms of leukemia may include fatigue, fever, weight loss, easy bruising or bleeding, and an increased risk of infections.

Brain and spinal cord tumors: Brain and spinal cord tumors are caused by the abnormal growth of cells in the brain or spinal cord. They can be benign (non-cancerous) or malignant (cancerous) and can occur anywhere in the brain or spinal cord. The most common types of brain tumors in children are astrocytomas, medulloblastomas, and ependymomas. Symptoms of brain and spinal cord tumors may include headaches, nausea, vomiting, changes in vision, changes in behavior or mood, and weakness or numbness in the limbs.

Lymphoma: Lymphoma is a cancer that develops in the lymphatic system, which is part of the immune system. The lymphatic system is made up of lymph nodes and vessels, which help to filter and transport fluids throughout the body. There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. Hodgkin lymphoma is more common in older children and teenagers, while non-Hodgkin lymphoma is more common in younger children. Symptoms of lymphoma may include swollen lymph nodes, fever, weight loss, night sweats, and fatigue.

Neuroblastoma: Neuroblastoma is a type of cancer that develops in the nerve cells. It most commonly develops in the adrenal glands, but can also be found in other parts of the body, such as the neck, chest, and pelvis. This type of cancer is most commonly found in children under the age of 5. Symptoms of neuroblastoma may include a swollen or hard tummy, pain in the bones, and signs of an eye tumor, such as a squint or drooping of the eyelid.

Rhabdomyosarcoma: Rhabdomyosarcoma is a type of cancer that develops in the muscles. It is typically found in the head and neck, genitourinary tract, and in the extremities. This type of cancer is most commonly found in children under the age of 10. Symptoms may include a lump or mass that is painless, but can be felt or seen under the skin, muscle weakness or pain.

Keep in mind that the symptoms and treatment of cancer will vary depending on the specific type and the stage of the cancer at the time of diagnosis, It’s important to consult with a pediatric oncologist who will be able to provide more information and personalized advice.
