What is a brain tumor
Brain tumor is an abbreviation for intracranial tumors, often resulting in dysfunction of the nervous system, serious life-threatening. Brain tumors and other parts of the body of the same tumor disease, is also divided into benign and malignant tumors, meningiomas and pituitary tumors are high incidence of benign brain tumors.
Commonly referred to as "brain cancer", refers to the brain malignancy, glioma is the most common type of brain cancer. Brain benign tumors "temperament" is more "moderate", the growth is more slow, the operation can cure, the recurrence rate is low; brain malignant tumor "temperament" more "brutal", usually require surgical resection combined with radiotherapy and chemotherapy, it is difficult to cure.
Most malignant brain tumors will relapse, the morbidity and mortality of patients with high, but also the current clinical neurosurgery need to focus on one of the difficulties to overcome.
Early symptoms of glioma
Compared with other types of cancer, the early clinical symptoms of glioma are not very typical, mainly can be summarized into three cases:
Tumor growth in the brain, the formation of a local mass effect, causing increased intracranial pressure, the patient will have headaches, severe headache, vomiting, blurred vision.
Headaches of brain tumors are not the same as those of normal headaches. Headaches of brain tumors usually begin to get painful when they get up in the morning and their pain can not be slowed down. Second, the emergence of limb hemiparesis, personality changes or vision loss, unilateral tinnitus, cognitive disorders, etc., these symptoms appear in a timely manner to the hospital for medical treatment.
2, nerve dysfunction
Cancer oppression adjacent brain tissue, resulting in local nerve dysfunction, such as oppression of brain motor function area, can cause limb fatigue, and even hemiplegia; oppression of language function area, will result in fluent speech, or even aphasia; oppression of the emotional function area, can lead to emotional Indifference and memory decline.
The existence of brain tumors can lead to abnormalities in the electrophysiological function of the brain, resulting in abnormal local discharge of the brain. The patient may have a seizure, which is commonly known as "epilepsy." Epileptic seizures in various forms, the most common is a temporary loss of consciousness, limb twitching, foaming at the mouth, incontinence.
Glioma screening method
Head CT is the screening of intracranial lesions of the "first barrier", fast, easy, major hospital emergency can be carried out. However, CT is only able to help detect intracranial lesions, in most cases it is impossible to judge the nature of the lesions and even miss some minor lesions. Normally, the doctor advises patients to have a head MRI after an abnormal CT scan. At present, MRI is the main means of diagnosis of glioma. If MRI is still difficult to diagnose, PET / CT is a good supplementary test.
