Types of Childhood Cancer
Leukemia is a form of cancer that affects the bone marrow and tissues which produce circulating blood cells, and is the most common of all childhood cancers. The different types of Leukemia that affect children include the following:
Acute Lymphoblastic Leukemia: Acute Lymphoblastic Leukemia is the most common childhood cancer. Nearly 75% of children with leukemia have Acute Lymphoblastic Leukemia, which is a cancer of the lymphoid cells within the bone marrow and the lymphoid organs of the body; all of which are involved in the body's immune system.
Acute Myelogenous Leukemia: Acute Myelogenous Leukemia is also known as Acute Non-lymphatic Leukemia, and is a cancer of the Myeloid blood cells. Myeloid blood cells are produced in bone marrow and help in fighting off bacterial infections.
Cancers of the Central Nervous System
Brain tumors: Gliomas are the most common forms of Brain Tumors, although there are many forms of them.
Neuroblastoma: Neuroblastomas are a form of cancer of the sympathetic nervous system. This form of cancer usually starts in the adrenal glands which are seated above the kidney.
Sarcomas are tumors which are cancerous and involve bones and soft tissues.
Osteosarcoma: Osteomas are Bone Sarcomas, and are the most common type of bone sarcoma. Tumors are many times found growing at the end of long bones of the extremities near the joints.
Ewings Sarcoma: A Ewings Sarcoma is a form of bone cancer that many times appears in the middle of a bone. This form of cancer is usually found in the middle of bones in the thighs, upper arms, hip bones, and ribs.
Soft Tissue Sarcomas:
Rhabdomyosarcoma: A Rhabdomyosarcoma is a form of soft tissue sarcoma which forms in the muscles. Rhabdomyosarcomas are usually found in the legs, arms, bladder, kidneys, neck or head of a person.
Lymphomas are tumors in the lymph tissues, parts of the human immune system. The different types of Lymphoma include:
Hodgkin Disease or Hodgkin's Lymphoma: Hodgkin's Disease, or, 'Hodgkin's Lymphoma,' is a form of cancer that affects the lymph nodes closer to the body's surface. These lymph nodes are found in the neck, armpits, and in the groin area.
Non-Hodgkin Lymphoma: A Non-Hodgkin's Lymphoma is a form of cancer that affects lymph nodes which are found deep within the body. These Non-Hodgkin's Lymphoma are of varying types and include Burkitt's, non-Burkitt's, and lymphoblastic lymphoma.
A tumor, or abnormal growth in the liver, is known as Liver Cancer. There are some common forms of Liver Cancer in children and they include Hepatoblastomas and Hepatocellular Carcinomas.
Cancers of the Kidney
There are also cancers of the Kidney which affect children, and different forms of them. The forms of Kidney cancer that affect children include Wilms Tumor, or,'Nephroblastoma,' and Clear Cell Sarcoma.
Other Types of Cancers
Retinoblastoma: Retinoblastoma is a form of malignant cancer that affects the retina in the eye of a child. The retina is a thin membrane in the back of the eye.
Germ Cell Tumors: Germ cell tumors usually show up in the testes of boys, the ovaries of girls, and in the bottom of the spine. Germ cell tumors may also appear in the middle of the brain, in the chest, or in the abdomen.
