Blastoma

Blastoma

Blastoma is a general term for any tumor in a group of cancers that almost uniquely affects children, which is thought to arise in precursor cells or blasts (immature or embryonic tissue). However, they can originate from different parts of the body, like the brain, liver, kidneys, nervous system, bones and the retina. Thus, people name each type of blastoma its own specific term according to its location in the body, such as the most common types (which make up of 25% of all malignant tumors in children younger than 15): hepatoblastoma (a tumor of liver), medulloblastoma (a type of brain tumor), nephroblastoma (a kidney tumor) and neuroblastoma (a tumor of neural origin). People still don’t know very well about the causes of blastomas, although the genetic errors, but not external factors are thought to be possible reasons, e. g. hepatoblastoma is related to certain genetic syndromes and inherited problems. Many blastomas are considered to be curable, and some localized neuroblastomas can even be cured with surgery alone.

People classify blastoma into different groups:

Glioblastoma

Medulloblastoma

Osteoblastoma

Rhabdomyosarcoma

Nephroblastoma

Pleuropulmonary blastoma

Retinoblastoma
