Brain tumor cells

Brain tumor, cells,

The deprivation, of adequate, oxygen, supply,

to certain, areas, of the brain,

occurs, when a tumor, makes, use of nearby, blood, vessels,

for its supply, of blood,

the neoplasm, enters, into competition, for nutrients,

with the surrounding, brain tissue,

neoplasm, release, of metabolic, end products ,

(e.g., free radicals, altered, electrolytes, neurotransmitters),

release, and recruit, cellular, mediators, (e.g., cytokines),

Brain tumor cells

disrupt, normal, parenchymal, function,

Necrosis, is the (premature), death, of cells,

caused, by external, factors, such as,

infection, toxin, or trauma,

Necrotic, cells, send the wrong, chemical, signals,

which, prevents, phagocytes, from disposing, of the dead, cells,

leading, to a build, up, of dead, tissue, cell, debris,

and toxins, at or near, the site, of the necrotic, cells,

Neoplasia, is the (uncontrolled), division, of cells,

as such, neoplasia, is not, problematic, but its, consequences,

Division of cells

Brain tumor, cells,

the uncontrolled, division, of cells,

means, that the mass, of a neoplasm, increases, in size,

and in a confined, space, the intracranial, cavity,

this quickly, becomes a problem,

because, the mass, invades, the space, of the brain,

pushing, it aside, leading, to compression, of the brain,

tissue, and increased, intracranial, pressure,

and destruction, of brain, parenchyma,

Mass effect of tumor

Increased, Intracranial, pressure,(ICP),

may be, attributable, to the direct, mass effect, of the tumor,

increased, blood volume,

or increased ,cerebrospinal, fluid, (CSF),

volume, may in turn have secondary, symptoms,

Atypia, is an indication, of abnormality, of a cell,

(which may be indicative, for malignancy),

Anaplasia, or dedifferentiation, loss, of differentiation,

of cells, and of their, orientation,

to one another, and blood vessels,

Anaplastic cells

Anaplastic, cells, have lost, total, control,

of their normal, functions, and many have,

deteriorated, cell structures,

Anaplastic ,cells, often, have abnormally,

high, nuclear-to-cytoplasmic, ratios, and many are

multinucleated,

Additionally, the nuclei, of anaplastic, cells,

are usually, unnaturally, shaped, or oversized, nuclei.

Tumor cells

Cells, can become anaplastic, in two ways,

neoplastic, tumor cells, can dedifferentiate,

to become, anaplasias,

(the dedifferentiation, causes, the cells, to lose,

all of their normal, structure,/function),

or cancer, stem cells, can increase,

in their capacity, to multiply,

(i.e., uncontrollable, growth, due, to failure,of

differentiation),
