Thus, tumors in this region provoke weakness, muscular rigidity and or face problems with sensitivity, HEARING, movements and deglutition, DOUBLE VISION and loss of the coordination when walking. Generally it is IMPOSSIBLE to completely remove the tumors in this region, due to its localization and importance. Already the tumors of the espinal marrow, that in an adult less measures 40 cm of length and of 2,5cm of width, having umpequeno volume, affect the two sides of the body, for example dormncia in the two legs. Some tumors can appear in NERVES CRANIANOS, will be in the auditory nerve can provoke the loss of the hearing, will be in the optic nerve can provoke the loss of the vision, will be in the trigmeo nerve can provoke the face paralysis. The tumors that have origin in the brain are PRIMARY CEREBRAL TUMORES (are great local disseminators, and hardly they migram stops other agencies), and the tumors that have origin in other agencies, as in the breasts or the pulmes, and then reach the brain, are called SECONDARY METASTTICOS OR CEREBRAL TUMORS (most common in adults). TYPES: MENINGEOMA: It has its origin in meninges, about 85% is benign and acomete about 25%de primary the cerebral tumors, with bigger incidence in people in the band of the 70 and 80 years, being 2 times more common in women of what in men.
GLIOMAS: About 42% of all the cerebral tumors including the benign ones they are gliomas and its incidence increases with the age reaching the peak between people in the band of the 75 to the 84 years of age. ASTROCITOMA: about 35%de the cerebral tumors OLIGODENDROGLIOMAS: about 4% of the cerebral tumors. EPENDIMOMAS: about 2% of the cerebral tumors. MEDULOBLASTOMAS: more common tumors in children and that they originate in the neurons of the cerebellum. They have fast growth, but they can be dealt and be cured with surgery and x-ray.
