Neuroblastoma is a type of childhood cancer that originates in the immature nerve cells of the sympathetic nervous system. These cells are called neuroblasts.
Hodgkin's disease is a form of cancer of the lymphatic system. During this disease, abnormal proliferation of a certain type of white blood cell (lymphocytes) is observed.
The doctor will observe more cases of neuroblastoma than Hodgkin's lymphoma because neuroblastomas start at birth and evolve with age, while Hodgkin's lymphomas start at adolescence but their incidence is lower compared to neuroblastomas.
