What is Childhood Cancer?

Cancer is one name for a group of diseases. Each type of cancer has its own name, treatment and chances for control or cure. Cancer happens when cells that are not normal grow and spread very fast in a certain part of the body. Normal cells grow, divide and then die. Cancer cells do not stop growing and dividing. Instead of dying, cancer cells can come together to form a tumor, such as:

  • Neuroblastoma
  • Brain tumors 
  • Wilms’ and other kidney tumors
  • Bone and soft tissue sarcomas
  • Retinoblastoma
  • Other rare tumors

Not all tumors are cancerous and not all cancers form tumors. Some cancers involve the blood and the organs that make blood in the body. These include:

  • Leukemia 
  • Lymphoma 
  • Histiocytic and lymphoproliferative disorders
