Neuroblastomas refer to cancers, which often start in neuroblasts i.e. early nerve cells present in the sympathetic nervous system. Because of this, you may find them at almost any place along with the respective nervous system.
How Common Is Neuroblastoma Or Is It A Rare Disease?
Neuroblastoma is one of the most common types of cancers that takes place in infants i.e. children less than 1year. It even accounts for approximately 6percent of the total number of cancers caused by kids or children. Every year, the United States observes about 800 new cases related to neuroblastoma and the number remains the same for several years.
The average age of kids diagnosed with neuroblastoma is within 1year and 2years of age. In rare conditions, doctors use ultrasound to detect the problem of neuroblastoma even in unborn babies. Approximately 90percent of the cancer cases underwent diagnose by 5years age. On the other side, neuroblastoma is rare in individuals exceeding 10years of age. Finally, in 2 among a total of 3 cases, the disease spreads already to lymph nodes or any other body part at the time of its diagnose via ultrasound. (2) (3)
A few key aspects of neuroblastomas are:
Often Starts In Nerve Ganglia: Most of the neuroblastomas start within the sympathetic nerve ganglia present in the patient’s abdominal area, while approximately half of them start within the adrenal glands.
Few Start In Ganglia Surrounding The Spine: A few of the neuroblastomas types of cancers start within the sympathetic ganglia surrounding the spine in the neck, chest or in the pelvic region.
Spreads In Rare Case: In rare cases, neuroblastomas spread at such faster rates that even doctors often fail to tell the exact place, from where it has already started. Even in some cases, neuroblastomas grow as well as spread at a faster rate, while in others it grows at a slow rate.
Cancer Cells Dying Vs Maturing: In some of the cases, cancer cells die in young children without any reason and in turn, the tumor goes away without any treatment.
However, in other cases, cancer cells mature on their own in the same way as regular ganglia cells, while stop dividing. This results in benign ganglioneuroma of the tumor. (1)
Common Causes Of Neuroblastoma Cancers
Nerve cells and medulla i.e. center cells of an individual’s adrenal glands develop from neuroblasts present in the fetus. These neuroblasts often grow as well as convert into matured nerve cells. Neuroblastomas often develop whenever regular fetal neuroblasts fail to become matured nerve cells and or medulla cells of the adrenal region.
Instead, they grow as well as divide consistently.
Neuroblasts may not mature completely in infants when they born. However, many of them mature into nerve cells eventually or simply die without forming neuroblastomas. In some of the cases, neuroblasts remain present in young infants, while grow continuously to form tumors. A few of them may even spread to the remaining parts of the patient’s body.
