A few words of thanks would be greatly appreciated.

Childhood cancer


Childhood cancer represents about 1% of all cancers in developed countries. Some forms of cancer are specific to children and, conversely, the majority of cancers found in adults do not exist in children. The following are the most typical: leukemia (bone marrow), lymphoma (lymph nodes) (both types representing approximately 40% of tumors in children), brain tumors (brain), Wilms (kidney), retinoblastoma (retinal ), neuroblastoma (adrenal and sympathetic ganglia), sarcomas (bone).


The symptoms of childhood cancer vary and are often misleading because they are accompanied by another general condition:
  • neurological signs;
  • bone or joint pain;
  • an unexplained mass close to a body orifice;
  • mass or abdominal pain;
  • one or more nodes without an obvious cause;
  • unexplained bleeding.


Childhood cancer can be detected with blood tests or different types of imaging tests depending on the suspected location: X-rays, CT, MRI, ultrasound, or other types analyzes of tissues or bone marrow.


Considerable progress has been made in regards to the treatment of childhood cancer. Indeed, the efficacy of chemotherapy and radiotherapy is increasing, surgical techniques are increasingly better controlled and diagnostics are becoming available earlier and earlier. On average, 4 out of 5 children are cured.
