What causes most of the brain tumors

Brain tumors, i.e., various kinds of brain tumors, are one of the common diseases in the nervous system, which are very harmful to the function of the human nervous system. They are generally divided into two categories: primary and secondary. Primary brain tumors can occur in brain tissue, meninges, cranial nerves, pituitary gland, vascular remnants of embryonic tissues and so on. Secondary tumors refer to metastatic tumors formed by malignant tumor metastasis or invasion of other parts of the body into the skull. In recent years, the incidence of brain tumors is on the rise, according to statistics, brain tumors account for about 5% of systemic tumors, accounting for 70% of children's tumors, and other malignant tumors will eventually have 20-30% of the transfer into the cranium, due to its expansion of infiltrative growth, in the cranium once according to a certain space, regardless of the nature of its benign or malignant, will inevitably make the intracranial pressure rises, compression of the brain tissues, resulting in damage to central nerves, endangering the life of patients. The patient's life will be jeopardized. Brain tumors can occur at any age, with 20-50 years old being the most common. In children, tumors of the posterior cranial fossa and midline are more common, mainly medulloblastoma, craniopharyngioma and ventricular meningioma. In adults, cerebral hemispheric gliomas are the most common, such as astrocytoma, glioblastoma, and ventricular meningioma, followed by brain tumors, pituitary tumors and craniopharyngiomas, neurofibromas, cavernous hemangiomas, cholesteatomas, and so on. There is no significant gender difference in the incidence of primary brain tumors, with men slightly more than women. The etiology and mechanism of brain tumor formation: traditional Chinese medicine believes that the formation of brain tumors is due to internal injuries and seven emotions, so that the internal organs dysfunction, coupled with the invasion of external evils, cold and heat, phlegm and turbidity, long-term gathering in a certain part of the body and become. The specialists have learned from all the experts, and after intensive research, they have summarized the causes of brain tumor as two kinds of internal and external factors, i.e., internal quality factors or susceptibility factors, external triggering factors or contributing factors, but one of them will not be onset. He believed that brain tumor belonged to the category of "headache" and "head wind" in the motherland medicine, and the causes of its pathogenesis were mainly kidney deficiency, loss of nourishment of marrow and sea, liver and kidney of the same origin, kidney deficiency and liver deficiency, liver wind and internal movement, evil and poison upturning the orifices, phlegm and turbid closure, obstruction of cerebral Luo, and blood and gas stagnation. The head is the meeting of all the yangs, and the general secretary of human's god, and it is most forbidden to be offended by evils. If one feels the evils of six lusts and poisons, and is directly hit by brain orifices or evils in the upper jiao, the qi is unfavorable, the meridians are impassable, the blood stasis and stasis are stagnant, and the internal and external evils are offended to the brain, and stay in the knot and become a block, and then develop into brain tumors. Research on tumor molecular biology shows that there are two types of genes closely related to the occurrence and development of tumor. One is oncogenes and the other is anti-tumor genes. The activation and transitional expression of anti-tumor genes induces tumor formation, while the presence and expression of anti-tumor genes help to inhibit tumorigenesis. Oncogenes can exist in normal cells and do not express tumor traits, when such cells are subjected to tumorigenic factors, such as viruses, chemical tumorigenicity and rays, the oncogenes in the cells are activated, the phenotype of the cells is altered, and the tumor traits are expressed, and these cells rapidly expand, thus forming a true tumor entity.Currently, it is believed that the factors that induce tumorigenesis are: genetic factors, physical factors, chemical factors and tumor-causing viruses. The location of brain tumors: the location of brain tumors often has obvious relationship with the tumor type, glioma occurs in the cerebral hemisphere, pituitary tumor occurs in the saddle region, acoustic neuroma occurs in the cerebellar pontine angle, angioblastic reticulum tumor occurs in the cerebellar fenestrae, cerebellar earth is good for the occurrence of medulloblastoma, and so on. Clinical manifestations of brain tumors vary greatly according to their pathological types, sites of occurrence and main speeds, but they are characterized by three features: 1) increased intracranial pressure; 2) symptoms of limited foci; and 3) progressive course of the disease. (I) Symptoms of increased intracranial pressure account for more than 90% of the patients with brain tumor, which are as follows: 1, headache, nausea, vomiting, headache mostly located in the forehead and temporal part, persistent headache with paroxysmal aggravation, often worse in the morning, and normal in the intervals. 2, optic papillae edema and other symptoms, which are not only the same as the symptoms of intracranial pressure, but also the same as those of the tumor. 2、Optic papillary edema and vision loss. Mental and consciousness disorder and other symptoms: dizziness, diplopia, transient black haze, sudden collapse, blurred consciousness, mental restlessness or indifference, epilepsy or even coma. 4、Vital signs changes: moderate and severe acute intracranial pressure increase, often caused by respiration, pulse, slowing down, blood pressure rise. (ii) Local symptoms and signs: it mainly depends on the site of tumor growth, so the local diagnosis of the tumor can be made according to the patient-specific symptoms and signs. (1) Clinical symptoms of cerebral hemisphere tumor: 1. Mental symptoms: mostly manifested as slow reaction, lazy life, memory loss, or even loss of memory, or loss of self-awareness and judgment in severe cases, and also manifested as irritable, easy to be agitated or elated. 2. 2、Epileptic seizure: including generalized grand mal seizure and limited seizure, frontal lobe is the most common, followed by temporal lobe, parietal lobe, occipital lobe is the least common, some cases have aura before convulsion, such as temporal lobe tumors, there are often illusions, vertigo, and other aura before seizure, and the parietal lobe tumors can have numbness of the limbs and other abnormal sensations before seizure. 3. Symptoms of damage to the pyramidal fasciculus: manifested by the tumor on the opposite side of the half-body or a single limb weak or paralyzed with positive pathological signs. 4, Sensory impairment: manifested as impairment of position sense, two-point discrimination sense, graphic sense, texture sense and solid sense of the limb on the opposite side of the tumor. Aphasia: motor and sensory aphasia. 6, Visual field changes: manifested as visual field defect, partial blindness. (2) Clinical manifestations of pterosynovial tumor: 1. Visual impairment: the tumor develops to the saddle and compresses the optic cross to cause visual acuity and visual field defect, which is often the main reason for pterosynovial tumor patients to come to the clinic, and the funduscopic examination can find primary optic nerve atrophy. Endocrine function disorders: For example, hypogonadotropic hypogonadism, which manifests as impotence and loss of libido in men. Women may show prolonged menstrual period or amenorrhea. Excessive secretion of growth hormone may lead to gigantism before maturity and acromegaly after maturity. (3) Clinical symptoms of pineal region tumor: 1. Symptoms of tetralogy of fallot compression: focusing on two aspects, i.e. visual impairment, pupil reaction to light and regulation reaction disorder, tinnitus, deafness; unsteady holding, staggering gait, horizontal nystagmus, incomplete paralysis of limbs, both sides of the pyramidal fasciculations; urolithiasis, somnolence, obesity, generalized developmental stagnation, and precocious puberty in males. (4) Clinical symptoms of posterior cranial fossa tumor: 1. Cerebellar hemisphere symptoms: mainly manifested as limb ***** dyskinesia on the affected side, but also may appear with reduced or no muscle tone on the affected side, sluggish knee tendon reflex, horizontal nystagmus, and sometimes vertical or rotational nystagmus. 2、Cerebellar earthworm symptoms: mainly manifested as trunk and distal lower limb ****jetty disorder, walking with the feet separated too far, staggering gait, or swaying from side to side like a drunkard. (3) Brainstem symptoms: the characteristic clinical manifestation is the emergence of cross paralysis, such as midbrain lesions, manifested as the lesion side of the motor nerve paralysis, pontine lesions, can be manifested as the lesion side of the eyeball abduction and facial muscle paralysis, the same side of the face with facial sensory disorders as well as auditory deficits, medulla oblongata lesions can be seen on the same side of the tongue muscle paralysis, pharyngeal paralysis, the posterior 1/3 of the tongue, loss of taste, and so on. (4) Cerebellar pontine horn symptoms: often manifested as tinnitus, hearing loss, dizziness, facial numbness, facial muscle twitching, facial muscle paralysis, as well as hoarseness, choking on water, the sick side of the **** dysarthria and horizontal nystagmus. (c) Progressive course of the disease, the tumor may not appear in the early stage of compression symptoms, with the increase of the tumor body, the clinical performance of different degrees of compression symptoms, according to the growth site of the tumor and the degree of malignancy of the tumor, the tumor grows at a different speed, the degree of symptomatic progression is also fast and slow. Treatment of brain tumor: Recently, the treatment of brain tumor at home and abroad mostly adopts surgery, chemotherapy, radiotherapy, X-knife, γ-knife and so on, but most of them are difficult to cure, malignant tumors have a short course, fast development, according to the degree of malignancy of high and low surgical resection of the number of or the sensitivity of radiation and chemotherapy, there are early and late recurrence of the growth of tumors in the brain stem, thalamus and other important parts of the brain stem is difficult to operate or can not be operated, X-knife, radiation and other treatments of tumors can have After X-knife, radiation and other treatments, the tumor can be reduced or the growth can be controlled for a short period of time, and then the tumor will not grow and recur. Benign tumors have a longer course of disease and slow growth, and those that are completely resected by surgery are not easy to recur, but those that are grown in the important parts of the brain stem can only be partially or mostly resected by surgery, and the tumor will recur and grow after surgery; the average survival rate of intracranial malignant tumors is less than one year after surgery, and the average survival rate of benign glioma, pituitary tumor, craniopharyngeal tumor, cholesteatoma, etc., is less than one year. Benign intracranial tumors such as gliomas, pituitary tumors, craniopharyngiomas, cholesteatomas, etc. are not easy to be removed cleanly by surgery, and γ-knife, X-knife and radiotherapy cannot kill the tumor completely, so most of the patients will still have recurrence after surgery. The expert group has been studying brain tumors for more than 30 years from the perspective of traditional Chinese medicine, and the unique insights on the pathogenesis and treatment of brain tumors with its breakthrough in traditional Chinese medicine theories have gained the attention of the medical profession and the wide recognition of the society, and he believes that: at present, although there are many methods of treating brain tumors both at home and abroad, most of them are difficult to be cured, and most of the patients will still have recurrences. patients will still recur. The occurrence of brain tumor and the different degree of headache, dizziness, paralysis, hearing, vision dysfunction, etc. caused by it are mostly common symptoms of liver and kidney insufficiency, liver qi, tendon, blood, kidney, essence, 1/2 of the main bone through the medulla oblongata, medulla oblongata, and the two interact with each other physiologically, and pathologically affect each other. In order to overcome the difficulties in the treatment of brain tumors, he combines the diagnosis of traditional Chinese medicine with that of Chinese and Western medicine according to Chinese medicine theory, and studies the pathology data carefully. He explored the Chinese medicine prescription, combined the Chinese medicine theory with modern medicine organically, and established a set of relatively perfect over-the-top anti-brain tumor theory by breaking through the traditional Chinese medicine method of activating blood circulation and removing blood stasis and attacking poison with poison after repeated practice and researches and demonstration. According to the different conditions of brain tumor, such as type, location, pathology, symptoms, etc., he identified and applied treatments, and started from tonifying the liver and kidney to calm the liver and extinguish the wind, tonifying the kidney and strengthening the brain, and took the nature of lifting and sinking and floating of traditional Chinese medicines to regulate the function of the organism of ascending, clearing and descending, and used the method of softening and dispersing the knots and activating blood circulation and removing blood stasis. Thus, the traditional Chinese medicine which acts on the tumor returns to the meridian and enters into the brain to reach the lesion, and makes the defeated tumor cells go up to the sweat and dissolve in the two stools, so that there is a door for the medicine to enter, and there is a way for the disease to come out. After unremitting efforts, dozens of natural Chinese herbs are screened out from thousands of kinds of Chinese medicines, and through the further conditioning, processing, extracting, and sublimation of the medicines, the series of anti-tumor series which can effectively kill or inhibit the tumor cells without injuring the normal tissues is finally developed. The series of anti-tumor Chinese medicines, which can be taken internally, can smoothly pass the blood-brain barrier, directly reach the lesion along the meridians, enter the tumor body with selective missiles, close the blood circulation of the tumor body, block the supply of blood and oxygen to the tumor body, cut off the malignant messenger of the tumor body, and inhibit the replication and transcription of the tumor cells. This series of drugs has remarkable curative effect on various types of glioma, pituitary tumor, brain tumor, craniopharyngioma, cholesteatoma, neurofibroma, pineal tumor, cavernous tubular tumor, nerve sheath tumor, chordoma, brain metastasis and other benign and malignant tumors in the cranium, so as to make tumor cells lose the ability to reproduce, thus making the tumor body gradually shrink, calcify or disappear. What are the 10 early signals of brain tumor? In real life, most people lack of understanding of brain tumor, and many patients do not get early diagnosis and treatment in time and have their lives cut short, therefore, it should attract people's attention. Now, the 10 early signals of brain tumor are described as follows. (1)Headache: it is more intense in nature, often occurs in the early morning, and sometimes wakes up with pain in sleep, but the headache will be gradually relieved or disappear after getting up and doing light activities. (2) Vomiting: due to the increase of intracranial pressure, resulting in the medullary respiratory center is stimulated, resulting in vomiting, vomiting most often occurs after the headache, in the form of a jet. (3) Visual impairment: Increased intracranial pressure will cause poor venous blood return to the eyeballs, resulting in bruising and edema, damaging the visual cells in the retina at the bottom of the eye, resulting in vision loss. (4) Mental abnormality: brain tumor located in the frontal lobe of the anterior part of the brain can destroy the mental activity of the frontal lobe, causing mental abnormality manifestations such as excitement, agitation, depression, depression, forgetfulness and fiction. (5) Unilateral limb sensory abnormality: the parietal lobe located in the middle of cerebral hemisphere is specialized in sensation, and the tumor in this part of the brain will often lead to unilateral limb pain, warmth, vibration, and diminished or lost of form and body discrimination sensation. (6) Phantom smell: temporal lobe tumor may appear phantom smell under its stimulation, which can smell a non-existent odor, such as burnt rice or burnt rubber and other odors. (7) Hemiplegia or staggering gait: lesions in the cerebellum are more specific, i.e., the patient often develops hemiplegia or staggering drunken gait after headache, vomiting, and visual disturbances. (8) Tinnitus and deafness: this kind of problem is often found when talking on the phone, i.e., one ear can hear, but the other ear can not hear. This performance is mostly the precursor of acoustic neuroma. (9) Gigantism: mostly seen in pituitary tumor. The manifestation is that the patient grows rapidly and develops acromegaly (big chin, big nose, enlarged lips, tongue, abnormally large hands and feet). (10) Growth cessation in young children: common in craniopharyngioma. The clinical manifestation is that the figure of 15 or 16 years old is only 5 or 6 years old, the sexual characteristics are not developed, the belly is full of fat, and it looks like the trend of "teenage blossoming". To sum up, the performance of brain tumor is various, so when the above signs appear, you should go to the hospital for a detailed examination quickly. At present, electronic computed tomography and magnetic **** vibration imaging can make a definite diagnosis of brain tumor at an early stage.
