What are the diagnostic methods for brain cancer?

Brain cancer is a malignant tumor in the brain, and the mortality rate of this disease is very high. Many brain cancer patients die of advanced brain cancer because brain cancer is not discovered in time in the early stage. Therefore, the diagnosis and detection of brain cancer is very important. Let me tell you about the diagnosis of brain cancer.

1 Fundus examination: observe whether there is optic nerve head edema. b. Optic nerve head edema is a sign of increased intracranial pressure. It is called the "three symptoms" of increased intracranial pressure together with headache and vomiting. However, it is only seen in one-quarter of brain cancer patients. Therefore, the possibility of brain cancer cannot be simply ruled out by a negative eye examination.

2 Skull X-ray: It helps to understand whether there is increased intracranial pressure, local destruction or hyperplasia of the skull, enlargement of the sella turcica, displacement of pineal calcification and pathological calcification in brain cancer, etc. It is helpful for positioning and qualitative diagnosis, but the positive rate of X-ray is less than one-third, so brain tumors cannot be ruled out due to negative X-ray results.

3. Electroencephalogram examination: It has the value of positioning brain tumors that grow fast in the cerebral hemispheres. It can be seen that the amplitude of the diseased side is reduced and the frequency is slowed down, but it is not very helpful for the diagnosis of brain cancer in the midline, deep in the hemisphere, and under the tentorium. The electroencephalogram developed after the 1970s can show the location and range of intracranial lesions in a graphical way. It is more sensitive to the diagnosis of brain tumors than conventional electroencephalograms. Its main manifestation is abnormal slow wave power in the tumor area and around the tumor area. It is an effective screening method before CT examination.

In the past, the diagnosis of brain cancer mainly relied on clinical symptoms, physical signs, neurological examinations, and positive results of X-ray head radiographs. Currently, head CT scans or magnetic resonance imaging are used, with a detection rate of over 90%, and can be as high as 99.7%, which helps to detect the disease at an early stage. Diagnosis of brain tumors must include localization diagnosis and qualitative diagnosis, so that a comprehensive judgment can be made and effective treatment measures can be determined.

The above is the diagnosis of brain cancer. Expert Tips: If you have the above symptoms, you can choose the appropriate treatment according to your symptoms, but do not delay the diagnosis, do not let your life be ruined in hesitation, you should go to a regular hospital for treatment in time to avoid delaying the disease and causing serious consequences.
