Under what circumstances do brain tumors occur?

First of all, the work pressure is relatively high, and there is often staying up late, and then there will be insomnia and dreams every night, and at the same time, it is also exposed to a lot of carcinogens, and then exposed to radiation substances for a long time

In the case of unhygienic diet, because at this time some cells in the brain will become diseased.

In early stage brain tumors, headaches, dizziness, blurred vision, nausea, sweating, and low resistance may occur.

The symptoms of brain tumors are mainly divided into two parts: 1. The symptoms of the brain itself, the more common ones are headache, nausea and vomiting, and the difference between other nausea and vomiting is slow and progressive aggravation. 2. Brain tumors can also have symptoms other than the head, including weakness on one side of the limb, numbness on one side, and even sometimes combined with epilepsy, that is, sudden loss of consciousness, convulsions of the whole body or sudden fainting, which can be early symptoms of brain tumors.

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.

At present, there is no special experiment and epidemiological investigation on this issue in China (for example: find two groups of ordinary people, one group has been using mobile phones for 10 years, and the other group has not used it for 10 years, and compare the incidence of brain tumors in the two groups after 10 years), so it cannot be subjectively assumed that the increase in the incidence of brain tumors is related to mobile phones.

In fact, the surge in the incidence of brain tumors is only related to the following two reasons: first, the improvement of public health awareness and health care level; The second is the progress of inspection methods, such as the application of magnetic resonance, CT and other equipment.

Due to the above reasons, many asymptomatic patients with brain tumors have been diagnosed early, which has led to a sharp increase in the incidence of brain tumors.

In addition, the medical community has confirmed that the onset of brain tumors is directly related to exposure to chemicals, excessive stress in life and work, genetics, and prolonged exposure to radiation.

Therefore, people should pay attention to the protection of the working environment in their lives, and at the same time, they should also have a comprehensive physical examination awareness, so that they can achieve early detection, early prevention and early prevention of brain tumors.

Brain tumors are not yet clear, and are generally believed to be formed by dual factors such as environmental factors and host factors. Among the environmental factors, there are physical, chemical, and biological factors, such as those that have been identified as being associated with brain tumors, including ionic and non-ionic radiations, pesticides, nitrosamine compounds, oncoviruses, and other infectious factors. Among the host factors, that is, the factors of the patient itself, include the patient's medical history, personal history, and family history.

In terms of molecular genetics, some tumors have a familial background or genetic factors, especially hereditary neuro-tumor syndromes associated with brain tumors.

Brain tumors are generally divided into two categories: primary and secondary. Primary brain tumors can occur in brain tissue, meninges, cranial nerves, pituitary gland, vascular residual embryonic tissue, etc. Secondary tumors refer to metastases that have metastasized to other parts of the body or metastases that have invaded the skull.

In the pathology, there are: glioma (including medulloblastoma, glioblastoma multiforme, star open cell tumor, oligodendroglioma, ependymoma), meningioma, acoustic neuroma, cerebrovascular tumor (including cerebral vascular malformation, cerebral hemangioblastoma), craniopharyngioma, pituitary adenoma, cholesteatoma, pineal tumor, glial cyst of the third ventricle, intracranial metastases and so on. Each type of ** is different.

The ** of most brain tumors is still unknown, but most scholars believe that it is the result of a combination of factors, which can be summarized as: abnormal development of brain embryonic tissue; genetic factors; chemical factors, carcinogens, etc.; Viral infections.

Brain tumors occur from brain tissue, but also from meninges or other intracranial tissues. Of course, it also includes malignant cancers that have metastasized from other parts of the cancer. The most common brain tumor is a gliocytoma that occurs as a result of brain nerve cells.

Once the onset of the disease should be prompted**, so as not to delay the disease.

Once a brain tumor appears, it can compress the nerves and cause various sequelae. Brain tumors are short for intracranial tumors, and brain tumors are not uncommon, with an incidence of about 1 in 10,000 per year. Among the systemic tumors, the incidence of brain tumors is second only to gastric, uterine, breast and esophageal tumors, accounting for about 2 of all systemic tumors.

Children are more likely to develop brain tumors, accounting for about 7% of all systemic tumors.

The factors that induce tumorigenesis are: genetic factors, physical factors, chemical factors and oncoviruses, from traditional Chinese medicine, the formation of brain tumors is due to internal injuries and seven emotions, so that the internal organs are dysfunctional, plus the invasion of external evils, cold and heat fighting, phlegm turbidity and internal stop, and long-term accumulation in a certain part of the body.

The specific causes of brain tumors are still under investigation. There is no exact answer to this question, and scientists currently believe that the formation of tumors is the result of a combination of related factors.

When the genes of the human body are mutated, tumor cells or tumor-related chromosomes are changed, resulting in the continuous proliferation of tumor cells, thus causing the production and growth of tumors.

Among the relevant influencing factors, the living environment, individual differences, human physical and psychological health, and the influence of diseases of other organs of the body play a very important decisive role, so brain tumors are affected by a variety of related factors, which act together on gene loci and change to lead to the formation of tumor cells.

There are many causes of brain tumors, which may be congenital factors or genetic factors, and there are many life factors that can cause brain tumors. It may be caused by long-term exposure to radiation or some environmental pollution. Brain tumors can be treated with surgery or chemoradiotherapy.

Brain tumor is a terrible brain disease, the harm is particularly serious, and the mortality rate is particularly high, more friends have symptoms of brain tumor, infringing on people's brain health, and will induce dizziness, headache and other symptoms, threatening the patient's life, we should be vigilant about brain tumor, clearly understand the precursor of the disease.

Patients with long-term onset will also have focal symptoms, patients will have motor and sensory dysfunction, resulting in the patient's limbs feeling weak, forming paralysis and numbness symptoms, accompanied by convulsions or seizures, and even affecting the patient's vision, resulting in visual impairment, the patient's visual field is seriously deficient, the mental decline is serious, and there may be mental symptoms, bringing more serious harm to the patient, we must pay attention to the changes in the brain. Beware of the occurrence of brain tumors and carefully understand the relevant symptoms.

Brain tumors first require contrast-enhanced CT and MRI to help determine whether the brain is benign or malignant. If it is a benign tumor, it is relatively small, there are no obvious symptoms, you can observe it first, and if it grows larger, you can consider surgery or intervention**. If it is considered to be a malignant tumor, if it can be operated, it is also for surgery**, and after surgery with radiotherapy and chemotherapy and other comprehensive**, if surgery is not possible, palliative radiotherapy, chemotherapy, and gamma knife can also be considered**.

Usually rest more, don't stay up late, and avoid overwork.

genetic factors; In the early stages of embryonic development, if it is affected by random changes such as gene defects or gene deletions, cells with the potential to become cancerous may be produced. If someone in the family has a brain tumor, the rest of the family may inherit a predisposing constitution for a brain tumor, increasing the probability of getting a brain tumor.

Environmental factors. Environmental factors range from physical, chemical, and biological environments. Hair dyes, pesticides and other chemicals can cause brain tumors, and the additives, preservatives and pigments contained in the diet continue to accumulate, which is easy to cause malignant lesions, especially nitrosamines in food will increase the probability of brain cancer.

There are many ways to treat brain tumors, whether brain tumors are benign tumors or malignant tumors, among malignant tumors are primary brain tumors, and tumors of other systems metastasize to the head. The primary meningioma is a benign tumor that can be removed surgically, and postoperative adjuvant radiotherapy or chemotherapy is not required after surgery.

Brain pain will occur, which will be accompanied by symptoms of dizziness, vomiting, and the body will be very uncomfortable, which is the manifestation of brain tumor. The better methods are craniotomy, intervention, minimally invasive surgery, and drug control, which are more traditional methods.

It will show slow reactions, and then it will also lead to some discomfort in the body, and there will also be a certain sense of pain, memory loss, resulting in decreased appetite, and then there will also be a series of symptoms such as dizziness, dizziness, and tinnitus.

Why does the hospital let people do multiple CT CTs when they have brain tumors? It is not good to check the number of people??
