CANCER Of The CENTRAL NERVOUS SYSTEM (BRAIN And SPINAL MARROW)

Cancer of the Central Nervous System (brain and spinal marrow)

It consists of the proliferation disordered and uncontrolled of the cells of support of the Central Nervous System.

Since the brain is protected in a rigid box, any increase of its volume is injurious, reason why all the tumors like malignant are considered.

Causes

In principle, although the last investigations aim towards the opposite, the nervous cells of the adult are not multiplied, reason why the cerebral cancers are not originated in them.

In order to work the nervous cells they need the aid of several auxiliary cells:

Astrocitos,

Oligodendrocitos,

cells of covering (meninges and epéndimo; external cover and commits of the brain) and

provinientes cells of the rest of the organism, like white globules.

From them these cancers come.

The brain also is the preferred place to metastatizar the cancers originated in other places of the body, mainly of lung, sucks and lymphatic.

Signs and symptoms

Simplifying, the cerebral tumors produce attributable symptoms to three main causes:

Irritation of the nervous weave, which produces convulsions.

Loss of function, that according to the affected zone, producira ':

Partial loss of vision,

aphasia (incapacity to speak),

paralysis and

losses of sensitivity...

Increase of the pressure within the skull:

Intense Dolores of head,

vomits in escopetazo,

alterations in the mobility of the pupils...

Attributable to all of them great changes of the personality can be presented/displayed.

Often the nervous weave cancers do not produce symptoms until they present/display a great volume surprising.

In advanced stages a coma takes place (loss of conscience), and even a descerebración (disconnection of the brain).

Factors of risk

Strangers.

Some rare genetic diseases present/display an increase of this type of tumors.

Prevention

Stranger.

Diagnosis and treatment

Before the presence of signs and suggestive symptoms, the clinical examinations will be made pertinent:

Complete neurological exploration,

Bottom of eye,

visual campimetría...

The analytical one does not play a great role.

The tests of imaginería are fundamental, mainly to escáner (T.A.C.) and resonance (R.M.N.) cerebral, that detects in a great proportion of cases tumors of more than 1 cm.

Before the doubt, tests will have to be made to discard the metastásico origin of the tumor, extending themselves the search to all the organism, by means of multiple tests.

The treatment of the cerebral tumors is basically surgical.

In certain cases the x-ray plays an important role, when being based in zones outside the reach of the bistoury.

The anticancerous medication jeuga a very modest paper in this type of tumors.

Nowadays, its genetic treatment is one of the investigated fields more, although, at the moment, with few results.

General Measures

Psychological advice for the patient and his family,

Average for the care and suplencia of déficits caused by the tumor, like railings, caminadores, etc.

Medication

Fundamentally to calm the pain and to control the convulsions, case of taking place.

Also to reduce the pressure within the skull.

Complications

The derived ones from the own growth of the tumor.

Prognosis

Some cerebral tumors, like meningiomas and craniofaringiomas, are curable by means of surgery.

Others, like astrocitomas, can be extirpated completely, depending on their accessibility.

The majority is incurables, limiting the surgery to reduce and to delay the effects of such (palliative treatment).

The quality of life of the patients can conserve until stages very outposts well.
