Brain Cancer Introduction

Grown in intracranial tumors known as brain tumors, including primary brain tumor from the brain parenchyma and transferred from other parts of the body to the brain secondary brain tumor. Primary brain tumor was divided according to their biological characteristics of benign and malignant. Benign brain tumor is slow-growing, the envelope is complete, no infiltration of the surrounding tissue and well-differentiated; malignant brain tumor growth, non-enveloped obvious boundaries showed infiltrative growth, poorly differentiated. Whether benign or malignant, can squeeze, the passage of normal brain tissue caused by increased intracranial pressure, threatening the lives of the people.
In recent years, the incidence of intracranial tumors upward trend According to statistics, the intracranial tumor accounts for about 5% of the whole-body tumor, accounting for 70% of childhood tumors and other malignancies, ultimately there will be 20-30% into the intracranial due invasive growth of its expansion in intracranial once, according to a certain space, regardless of its nature is benign or malignant, are bound to make the increased intracranial pressure, brain pressure, leading to central nervous system damage, endangering the lives of patients.
Intracranial tumors can occur at any age, the most common in 20-50 years. Children posterior fossa and midline tumors were more common, mainly for medulloblastoma, craniopharyngioma and ependymoma. Most common adult cerebral hemisphere gliomas, astrocytoma, glioblastoma cell tumors, ependymal tumors, etc., followed by meningiomas, pituitary tumors, craniopharyngioma, neurofibroma, cavernous hemangioma, cholesteatoma. The incidence of primary intracranial tumors no significant gender differences, men slightly more than women.
How brain cancer is caused by acidic and brain cancer
Cause acidic diet, lifestyle factors such as long-term decline in the functioning of the whole body, causing kidney, liver and kidney origin, kidney liver is also true, and thus caused on coke metabolic cycle slows down, blocking the cerebral arterial blood gas stagnate. Then some brain parasites, viruses, blooms, causing a severe brain injury.
Acidification of brain tissue fluid, brain cells in the acidic fluid, thus the formation of brain cells decline in dissolved oxygen, resulting in the decreased activity of the cell metabolism circulation slows down to 65% of normal, normal cells can not survive, but also willing to change chromosome take initiative mutated cells, to phenotype changes, tumor traits to be expressed, these cells rapidly amplified so as to form a true tumor entities.
In addition, there are other organizations of cancerous occurred due to acidic body, because of the decline in brain function, brain tissue fluid acidification cancer swoop, caused by a brain tumor.
What are the early signs and clinical manifestations of brain cancer
Depending on the pathological type, location, the main difference in speed, and then with three characteristics: 1, increased intracranial pressure; 2, localized disease symptoms; 3, the progressive course of the disease.
(A) increased intracranial pressure symptoms accounting for more than 90% of patients with brain tumors, and its performance:
1, headache, nausea, vomiting, headache located in the forehead and temporal paroxysmal intensification of persistent headache, constant headache in the morning, the intermittent period can be normal.
2, papilledema and vision loss.
Spirit and disturbance of consciousness and other symptoms: dizziness, diplopia, transient amaurosis, cataplexy, confusion, mental anxiety or apathy, seizures can occur, and even coma.
Changes in vital signs: moderate and severe acute increased intracranial pressure, often caused by respiration, pulse, slow down blood pressure.
(B) local symptoms and signs: depending on the site of tumor growth, according to the patient's specific symptoms and signs to make a diagnosis of tumor localization.
(1) clinical symptoms of cerebral hemisphere tumors:
Psychiatric symptoms: more performance as unresponsive and lazy life, recent memory loss, and even loss, severe loss of insight and judgment, also showed bad temper, irritability or euphoria.
2 seizures: including systemic grand mal and limitations of seizures, the frontal lobe is the most common, followed by the temporal lobe, parietal lobe, occipital lobe is the most rare, in some cases, before the seizure aura, such as the temporal lobe tumors, seizures often the aura of fantasy, dizziness, numbness before the onset of the parietal lobe tumor and other abnormal sensations.
3 pyramidal tract damage symptoms: showed positive pathologic tumor contralateral bust or a single limb is weak or paralyzed.
4, sensory disturbances: performance tumor contralateral limb position sense point discrimination, graphic feel, material sense, entities sleep disorder.
5 aphasia: divided into movement and sensory aphasia.
6, the vision changed: the performance of visual field defects, hemianopia.
(2) the clinical manifestations of sellar tumors:
A visually impaired: tumor development to the saddle on the oppression of the optic chiasm cause vision loss and visual field defects, often is the main reason for treatment of the sella tumor patients come fundus examination can be found in the primary optic atrophy.
2, endocrine disorders: such as hypogonadism, male performance for impotence, loss of libido. Served in mature female performance to extend the period of menstruation or amenorrhea, the secretion of growth hormone cause gigantism, acromegaly mature fat blind performance.
(3) The pineal region tumor clinical symptoms:
Quadrigeminal oppressed symptoms: focus on performance in two aspects, namely: visual disorders, pupillary reaction and adjustment reaction disorder, tinnitus, deafness; unstable hold things, staggering gait, eye level tremor, limb incomplete paralysis on both sides pyramidal signs; diabetes insipidus, lethargy, obesity, body growth pause, male visibility precocious.
(4) the posterior fossa tumor clinical symptoms:
1, cerebellar hemispheres symptoms: mainly affected limb ataxia, ipsilateral muscle tone or tension, knee tendon reflexes slow, eye level tremor, sometimes there may be vertical or rotational tremor may also occur.
2, the cerebellar vermis symptoms: mainly for the torso and distal lower extremity ataxia, walking two feet separated too far, staggering gait, or from side to side, such as drunk.
Brainstem symptoms: clinical manifestations characterized cross palsy, such as brain lesions more than performance oculomotor nerve palsy to the side of the lesion, pontine lesions may manifest as lesions the side eyeball outreach and facial muscle paralysis, the same side Ministry sensory impairments, and hearing impairments, medullary lesions the ipsilateral tongue muscle paralysis, throat paralysis, 1/3 of the tongue taste disappeared.
Cerebellopontine angle symptoms: usually presents tinnitus, hearing loss, vertigo, facial numbness, facial muscle twitching, paralysis of facial muscles and hoarseness, cough potable water, the disease side ataxia and level shock eye.
(C) the progressive course of the disease, the cancer early may not symptoms of oppression, with the increase of the tumor, the clinical often show symptoms of varying degrees of oppression, according to the level of tumor location and degree of malignancy, tumor growth speed the pace, the symptoms progress the extent to also be fast or slow.
