Glial cells are nerve helper cells.
Glial cells are readily capable of mitosis (replication) whereas neurons cells supposedly less so.
There is a pleomorphic theory about pathogenic causes of disease that says that each pathogen could mutate to a form of disease that is best suited to the medium of the disease site. If this is so, then a pathogen that attacks uniquely the glial cells may exist that triggers various diseases including cancer. However, further research for any proof or investigation of this may be reported elsewhere.
When cancer happens, normal cells are turned from a oxygen sugar oxidative (aerobic) metabolism controlled by the mitochondria to a sugar fermentation (anaerobic) metabolism that is not under mitochondrial control. The mitochondria control what is called programmed cell death of which wikipedia states there are two types:
Professor John Beard surmised that cancer was partly caused by a deficiency of the pancreatic enzymes trypsin and chymotrypsin. People on diets rich in animal meat were losing the preventative effects of these enzymes because the latter were being constantly employed to break down these animal proteins. These pancreatic enzymes were shown by Beard to strip down and digest the protein coating of cancer cells. It was this life-saving action that was described by the Edinburgh embryologist in his Unitarian or Trophoblastic Thesis of Cancer.
Even if the brain cancer is stopped, many say that the remaining dead tumor tissue that persists can still kill the patient by just statically obstructing normal biological functions, and that protein digestive enzymes are key to their elimination and subsequent patient recovery.
Jim Sheridan / cancell / cantron, Gerson Therapy, the Budwig diet, Royal Rife frequency machine treatments, the Beck Protocol, Laetrile / amygdalin treatments, cansema black salve capsules, herbal remedies recommended by H. R. Clark, and numerous other naturalistic, holistic dietary approaches can often be combined to help.
The underlying cause or trigger of cancer is likely one or more toxins, or exposure to certain fields of electromagnetic energy of frequencies known to cause damage, or microbial pathogenic causes of disease.
Heavy metals are known toxins. They can be chelated out of the blood and other tissues.
The pancreas could be overtaxed by eating meat so that no more digestive enzymes are available to eat the abnormal protein coating from cancerous cells, exposing them to the body's immune system.
Peroxisomes, and glutathione function may be poor.
Certain serum levels of vitamins could be very poor causing disease. Many doctors have noted recent research by UCSD into vitamin D that indicate that many diseases including cancer can be avoided if the serum levels of vitamin D are within a healthy range.
The theory goes that sometimes the body's own repair system can go out of control, where adult stem cells, fibroblasts, and similar undifferentiated cells meant to go to a damaged area and repair or replace damaged tissues, keep replicating out of control because they no longer respond to the body's natural chemical and electrical signals to stop the replication / repair process.
Other theories of the illness are that cancer can be caused by pathogenic infections of microbes or fungus. Both of these types of infections can feed off of injured tissues that are unable to defend themselves against these foreign infections. As these damaged tissues are being consumed by these infections, the body's other systems kick in to isolate the infection by the growth of tumors to stop their spread. As the bodies immune system weakens, the underlying cause of the disease may spread to other parts of the body.
Apoptosis, programmed cell death, is an important mechanism in cancer treatment.
When cancer is malignant, the cells no longer follow their directed, programmed death, and continue to replicated out of control.
The following is an abstract from a medical study indexed by Medline / Pub Med:
Glial cells.
Astrocytes
There are 100 billion neurons in th human brain and about 1-5 trillion glial cells (that's 10-50 times more!). Most are astrocytes.
Nervous tissue consists mainly of nerve cells and glial cells. Glial cells are the most abundant cell types in the central nervous system.
There are many neurons in the human brain (~ 100 billion) but glial cells outnumber neurons by 10 fold. Therefore, the most abundant cell type in our brain would be glial cells of which astrocytes (a type of glial cell) is the most numerous. http://en.wikipedia.org/wiki/Neuron
That is not the fatty 'material'. They are Glial cells derived from the mesoderm. The nerve cells are derived from ectoderm. The neural cells do not divide and so cancer do not arise from them. The malignancy in brain usually arise from these glial cells.
Microglia.
Astrocytes
its the boobs
They form cancers.
Myeloma.
The most abundant cells and are responsible for protecting and supporting the neurons in transmitting cognitive/ sensory information, however do not actually conduct electrical impulses themselves.
