How are brain tumors caused and how are brain tumors caused?

Combined with Yang Liqun's explanation, I still have something to say: "Because of long-term overwork, there is no suitable supplementary sleep or insufficient sleep time can also cause brain tumors." Some children have brain tumors that can be verified like this:

Children are still very big in their teens, of course, this may also be caused by premature development, dizziness may also be caused by brain tumors, but it is still possible to be caused by irregular diet. It is recommended to go to the hospital for examination first, and even if you have a brain tumor, it can be treated and solved early. "My finish, thank you all for seeing the end.

At present, there is no accurate conclusion on the specific cause of brain tumors, and most scholars believe that the occurrence and development of brain tumors are the result of the combined action of congenital genetic factors and acquired factors, and are by no means determined by a single factor. Congenital factors are more common in family genetic history, and a tendency to congregate family members can be found in family history. Long-term exposure to carcinogenic chemicals, long-term exposure to high-dose radiation pollution, and poor living habits, including eating habits, sleeping habits, and long-term exposure to excessive electromagnetic radiation may induce the occurrence and development of brain tumors.

Therefore, for patients with brain tumors, it is often caused by a combination of factors.

The causes of head tumors are currently inconclusive in scientific research, and so far there is no accurate data in this area, and head tumors are divided into benign tumors and malignant tumors. Benign tumors are characterized by a relatively slow growth rate of tumors, relatively clear boundaries, complete envelopes, and no spread and metastasis.

Malignant tumors of the head are characterized by relatively fast growth rate, unclear borders, burrs, no complete capsule, generally solid tumors, relatively hard texture, and abundant blood**. If the malignant tumor of the head can be detected early, diagnosed early, and the tumor has not spread and metastasized, most patients can be removed by surgical resection.

Hello: Problem analysis and guidance: Intracranial tumors, also known as brain tumors, are still unknown, and tumors occur from the brain, meninges, pituitary gland, cranial nerves, cerebral blood vessels and embryonic residual tissues, which are called primary intracranial tumors.

Malignant tumors that metastasize from other organs and tissues of the body to the skull are called secondary intracranial tumors.

Hope it helps, and I wish you good health!

When it comes to brain tumors, everyone will definitely smell the discoloration of tumors, and if we tell you some knowledge about brain tumors, you will definitely let go of a lot of unnecessary worries.

1. There are many types of brain tumors: some are primary, and the common ones are glioma, meningioma, and pituitary tumor. Some are secondary, and the common ones are lung cancer brain metastases, breast cancer brain metastases.

2. Brain tumors can grow in various parts of the brain, and some have fixed parts, such as pituitary tumors in the sellar region and acoustic neuromas in the pontine cerebellar angle area. Some tumors grow everywhere, such as meningiomas and gliomas, which can grow anywhere in the skull.

3. Tumors in the brain, some of which have symptoms very early, such as headaches, seizures, visual impairment, hearing impairment, endocrine disorders, etc. Some are asymptomatic for a long time and are only detected during a physical examination or CT scan at the time of a head injury.

4. For further examination of brain tumor, neurosurgeons will propose different examination methods according to the location of the tumor, such as enhanced CT, magnetic resonance spectroscopy, magnetic resonance arterial angiography, magnetic resonance venous angiography, etc. Others do a lumbar puncture to test for cerebrospinal fluid. Each patient has different tests.

5. Some cerebrovascular diseases sound like "tumor", but they are not actually brain tumors, such as cerebral aneurysms are local bulges of the cerebral blood vessel wall, and cerebral cavernous hemangiomas are occult vascular malformations.

6. Brain tumors are divided into benign and malignant, but malignant tumors have a relatively low grade, that is, close to benign, such as low-grade glioma, benign tumors with malignant transformation, or malignant behavior, such as hemangioperithelioma.

7. Some symptoms of brain tumors are related to the location of the tumor, such as tumors of the brain parenchyma, which may be prone to epilepsy, and some are related to the nature, such as pituitary tumors, which may present with endocrine symptoms. There are also compressive symptoms, such as sellar tumors that manifest as visual field impairment.

8. There are many ways to treat brain tumors, first of all, surgery, most tumors can be operated on now, and the surgical effect is not bad; For tumors in deep functional areas, we can also take radiation**, and some tumors are also more sensitive to radiation**, such as germ cell tumors and lymphomas. There are also many radiation** methods, such as gamma knife, cyberknife, proton knife, etc. There are also chemotherapy methods, etc.

After having a comprehensive understanding of brain tumors, there is no need to panic when encountering brain tumors, as long as a specialist doctor gives a comprehensive and accurate plan, with a good doctor, there will be more ideal consequences.

Hello, the occurrence of meningioma may be related to certain internal environment changes and genetic mutations, not caused by a single factor, it may be related to brain trauma, radiation exposure, viral infection and bilateral acoustic neuroma.

The occurrence and development of brain tumors are restricted and affected by a variety of factors, and are by no means determined by a single factor. There are mainly congenital genetic factors, oncogenes and chemical factors. In addition, poor living environment, eating habits, lifestyle habits and occupational factors may cause the occurrence and development of brain tumors.

First, the main **.

2. Oncogenes: Cancers from other parts can metastasize to the brain, thus forming brain metastases.

3. Chemical factors: Some foods or medicines contain carcinogens, which can cause brain tumors or cancers in other parts of the body.

2. Predisposing factors.

1. Poor eating habits: long-term consumption of smoked, barbecued, pickled, and mildew-prone foods will greatly increase the incidence of brain tumors.

2. Bad living habits: The occurrence of brain tumors is closely related to cigarettes, mainly due to the fact that cigarettes contain more than 100 kinds of harmful substances to the human body. Among them, benzopyrene is one of the three major carcinogens, which can induce brain tumors by allowing carcinogens to enter the body.

3. Environmental factors: It comes from serious air pollution in areas with developed industry and transportation. Long-term inhalation of harmful gases into the body can cause brain tumors.

4. Occupational factors: long-term exposure to radioactive substances such as uranium and radium and their derivatives, carcinogenic hydrocarbons, asphalt, petroleum, iron, tin and other substances can induce brain tumors.

The causes of brain tumors are briefly summarized, let's say, one that comes down to congenital factors. For example, some creatinine tumors may be related to the birth situation. The second is like genetic factors, such as neurofibromatosis.

The third factor, such as trauma, is that some people who have suffered a traumatic brain injury may also cause tumors to grow. The fourth immune factor, low autoimmunity, such as AIDS, may be infected with some special tumors. The fifth is like physical factors, physical factors, simple examples, we often use mobile phones, ionizing radiation like these problems will lead to tumors, and there is no conclusion at present.

The sixth aspect is chemical factors, such as diet, or exposure to special chemicals, which may also cause tumorigenic effects. Another is the biological factor, for example, infection with some special viruses, such as Epstein-Barr virus, may cause the growth of brain tumors.

Causes of brain tumors are staying up late, overeating, and so on.

Hello! What causes pediatric medulloblastoma? (1) Causes of medulloblastoma This disease is a common central nervous system tumor, which is a highly malignant tumor, originating from the cerebellar vermis or the posterior medullary sail primitive embryonic residual tissue of the fourth ventricular roof, accounting for 10% 20% of primary brain tumors in children, 40% of posterior fossa tumors, and is more common in children.

2) Pathogenesis The tumor is located in the vermis of the cerebellum about 80%, most of them grow to the fourth ventricle, the older ones (13 15 years old) a few are located in the cerebellar hemisphere, some people explain that medulloblastoma ** is in the medullary sail proliferation center, and the older ones can develop from the remnants of cells in the extracerebellar granule layer, and a very small number of tumors can develop through the occipital foramen magnum down to the upper cervical spinal canal (that is, the tumor in the cerebral descending occipital foramen magnum area), the tumor is highly malignant, and often the tumor cells fall off and spread and metastasize along the cerebrospinal fluid, which can be implanted to the cauda equina, In the spinal cord or on the surface of the brain, ventricles, etc., some people have statistics that cerebrospinal metastases account for 12% 46%.

Pathogenesis At present, several theories are proposed according to the pathogenesis characteristics and pathology of certain tumors, as well as some basic experimental research. (1) Genetic theory: In the field of neurosurgery, some tumors have obvious familial tendencies, such as retinoblastoma, angioreticulocytoma, multiple neurofibromas, etc., which are generally considered to be autosomal dominant tumors with high penetrance.

2) Virus theory: Experimental studies have shown that some viruses, including DNA viruses and RNA viruses, can induce brain tumors if inoculated in animal brains. (3) Physics and Chemistry Theory:

Among the chemical factors, polycyclic aromatic hydrocarbons and nitric acid compounds, such as methyl choleracene, benzoratio, methylnitrosourea, nitrosopiperidine, can induce brain tumors in some animal experiments. (4) Immunosuppressive theory: The application of immunosuppressive drugs in organ transplantation will increase the risk of intracranial or peripheral tumors.

5) Embryo remnant theory: craniopharyngioma, epithelioid and dermoid cysts, teratomas, chordomas obviously occur in embryonic tissues remaining in the brain, and these residual tissues have the potential to proliferate and differentiate, and can develop into tumors under certain conditions.

Condition analysis: Hello, for your case, it is recommended that you go to the hospital for surgery ** to remove the tumor, and at the same time, the nature of the tumor will be pathologically checked after the operation.

Suggestions:

Brain tumors are a large group of diseases, not one disease, and different types of brain tumors form different types of brain tumors. Specifically, brain tumors can be broadly divided into two types: one is secondary brain tumors, which are called brain metastases.

This type of tumor is mainly due to malignant tumors in various parts of the body, such as lung cancer, breast cancer, thyroid cancer, prostate cancer, stomach cancer, colon cancer, liver cancer, etc. Tumor cells in these areas spread through the bloodstream to the brain, forming brain metastases in the skull. Another type of brain tumor is primary brain tumor, common meningioma, glioma, pituitary tumor, etc., this kind of tumor is mainly due to the brain itself, there are cells with genetic mutations and uncontrollable proliferation, thus forming primary benign tumors and malignant tumors in the brain.

At present, glioma** has not been clarified, and most scholars believe that it is the result of a combination of factors. In summary, there are: abnormal development of brain embryonic tissue; genetic factors, in recent years, gliomas have been thought to have a genetic predisposition; Chemical factors, in recent years, it has been suggested that the carcinogens methyl nitrate urea or ethyl nitrosourea can cause glioma either orally or intravenously; Some foreign scholars have used some viruses to induce small tumors in a variety of animals, but they have not been confirmed in humans.

It is recommended to try it with R H 2 to see how it works.
