Is brain cancer the same as a brain tumor? How brain tumors are caused

Analysis: Hello, the nature of these two types is different, brain cancer must be malignant, brain tumors include benign and malignant.

Suggestions:

Analysis: Brain tumor is a benign tumor.

There were no sequelae or minor sequelae after the surgery.

Brain cancer is a malignant tumor.

It will move to other sites.

Not easy**. The symptoms of brain cancer and brain tumour are similar.

Both have symptoms of brain compression. Suggestions:

Is a brain tumor a cancer, a brain tumor can be divided into a benign tumor and a malignant tumor, for a malignant tumor, it can be counted as a kind of cancer, and a malignant tumor can be divided into a primary brain malignant tumor and a secondary brain malignant tumor, the primary brain malignant tumor, with glioma as a common one, among which the most malignant glioma, like glioblastoma, can be counted as a cancer with a very high degree of malignancy, his five-year survival rate is only about 5, and tumors of our other systems, For example, the five-year survival rate of pancreatic cancer is comparable, so the degree of malignancy is still relatively high.

Another type of malignant tumor of the brain, called secondary brain tumor, is mainly caused by cancer in various parts of the body, cancer through blood circulation, metastasized to the brain, this tumor is also relatively malignant, if there is no reasonable surgery**, and follow-up**, the patient often dies within 1 to 3 months, so brain cancer still needs to be timely**, and the effect is sometimes not very ideal.

First, the meaning of brain tumor:

At present, it is recognized that long-term exposure to uranium, radium and other radioactive substances and their derivatives, carcinogenic hydrocarbons, arsenic, chromium, nickel, copper, tin, iron, coal tar, asphalt, petroleum, asbestos, mustard gas and other substances can induce brain cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.

Introduction to the pathology of brain tumors.

Tumours that grow within the skull are commonly known as brain tumors and include primary brain tumors that occur from the brain parenchyma and secondary brain tumors that metastasize to the skull from other parts of the body. Primary brain tumors are divided into benign and malignant according to their biological characteristics. Benign brain tumors grow slowly, have a relatively complete capsule, do not infiltrate surrounding tissues and differentiate well; Malignant brain tumors grow rapidly, have no envelope, have no obvious boundaries, show invasive growth, and are poorly differentiated.

Whether benign or malignant, it can squeeze and move normal brain tissue, causing an increase in intracranial pressure and threatening human life.

Second: brain tumor is a very serious disease, first, due to the gradual enlargement of the brain tumor, the formation of intracranial mass lesions, and often accompanied by peripheral cerebral edema, when the compensation limit is exceeded, that is, the intracranial pressure increases. Intracranial pressure is increased when a brain tumor obstructs cerebrospinal fluid circulation or compresses a vein, causing impaired venous return. If hemorrhage, necrosis, and cyst formation occur within the brain tumor, the progression can be accelerated.

Second, the brain tumor is enlarged, the local intracranial pressure is the highest, and the pressure gradient between the cavities in the skull causes brain displacement, and the gradual aggravation forms brain herniation. Supratentorial hemisphere tumors can produce cerebral hypothetical herniation with the cingulate moving back across the midline, which can cause wedge necrosis. The pericallosum artery can also be compressed and displaced, and in severe cases, cerebral infarction in the ** area may occur.

3. Patients with brain tumors are in a coma, their blood pressure rises, their pulse is slow, their breathing is deep and irregular, and they may have decerebrated rigidity. When intracranial pressure increases to a critical point, intracranial volume continues to increase slightly, and intracranial pressure increases rapidly. When intracranial pressure is equal to arterial pressure, cerebral vascular paralysis, cerebral blood flow stops, blood pressure drops, and the patient dies soon.

In order to carry out formal professional ** as soon as possible, most of the cases accepted are missed the best time, which increases the difficulty of ** and also brings irreparable damage to patients and their families.

Chemotherapy for brain tumors, especially for malignant tumors, is a must. But I want to say that there are some benign tumors, which may have this kind of dysplasia that we call atypical hyperplasia, and it may also require further chemotherapy, especially for patients with glioma, after surgery, according to how high the level of pathological characteristics is, further chemotherapy should be carried out, the so-called chemical **. Therefore, in general, most patients with malignant tumors of the brain need chemotherapy.

But this kind of chemotherapy now, we have targeted drugs, and some of the damage caused by this chemotherapy to the human body is relatively reduced. However, chemotherapy should also be selected according to the patient's own physical quality, as well as the degree of tumor resection, whether it can be carried out to our so-called several courses, if a patient can only one course of treatment can not persist, if some of his later chemotherapy may not reach our expected number of courses, so his prognosis is relatively poor, but the vast majority of malignant tumors still need chemotherapy.

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.

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.

A brain tumour is a benign or malignant intracranial tumor. It has a high incidence, and according to statistics, about 230,000 people worldwide are diagnosed with this disease every year. The essence of this disease is the abnormal proliferation of cells within the brain tissue, which can cause the brain tissue to compress the surrounding nerves and blood vessels, causing different symptoms.

So, why do brain tumors occur? What are its symptoms?

First, let's take a look at why brain tumors occur. There are many causes of brain tumors, mainly in the following aspects:

1.Genetic factors. There are some genetic diseases such as neurofibromatosis, familial brain tumor syndrome, etc., which are associated with the occurrence of brain tumors.

2.Environmental factors. Long-term exposure to harmful environments such as radiation can easily lead to the development of brain tumors. In addition, the presence of certain chemicals, viruses, etc., can also cause brain tumors.

3.Lifestyle habits. Intake of malnutrition, unhealthy food, excessive alcohol consumption, staying up late and other unhealthy lifestyle habits can also lead to the occurrence of brain tumors.

In addition, age, gender, work environment, mental stress, etc. are also related to the occurrence of brain tumors. At the same time, we should also pay attention to the fact that the cause of brain tumor may be different for each person, so we need to do a routine physical examination before the onset of the disease to ensure the health of the body.

Next, let's look at the symptoms of brain tumors. Symptoms of brain tumors vary depending on their type, size, location, and degree of invasion. Based on clinicians' observations and patient feedback, brain tumors may present with the following symptoms:

1.Headache. Headache is one of the most common symptoms. Brain tumors often cause pressure or severe pain in the head, and headaches vary depending on the size and location of the tumor, and in some patients it lasts for hours or even days.

2.Low. When a brain tumor invades brain tissue, it causes an inflammatory response, resulting in persistent low-grade fever and decreased resistance.

3.Epilepsy. Brain tumors often compress or destroy brain tissue, causing nerve cells to go out of control, causing seizures.

4.Aphasia. Brain tumors often invade the closed language center of the human brain, resulting in aphasia or decreased ability to express themselves in aphasia.

5.Vision problems. Brain tumors can compress the optic nerve, causing blurred vision and blindness.

In addition to the above symptoms, patients often experience effects on hearing, smell, and balance, as well as limb movement disorders. Absolutely
