Blastoma
Blastoma Definition
A blastoma is a type of cancer that is brough about by malignancies in precursor cells, often called blasts. It is a tumor thought to result from embryonic tissue. The term "blastoma" is generally used as part of the name for a tumor as, for examples, in glioblastoma and medulloblastoma (types of brain tumors), hepatoblastoma (a liver tumor), nephroblastoma ( Wilms tumor of the kidney), neuroblastoma (a childhood tumor of neural origin), osteoblastoma (a bone tumor) and retinoblastoma (a tumor of the retina). A blastoma is a neoplasm composed of immature and undifferentiated cells derived from the blastema of an organ or tissue.
Blastoma Symptoms and Signs
Blastoma is asymptomatic in its early stages, meaning symptoms do not display themselves at the onset of the disease. People who have blastomas typically experience pain, weight loss and lethargy. They may feel tired all the time due to languor. Patients also complain of impaired vision and impaired hearing, and their liver and spleen might enlarge and grow in size. Other symptoms are neurological.
