Are there any symptoms of brain cancer in the early stages?

Brain tumors are divided into benign tumors and malignant tumors. The most common symptoms are dizziness and nausea. Because in the early stage, the symptoms of brain tumors are not obvious and are often easily ignored. Therefore, once discovered, you should immediately go to a large regular hospital for surgery. Brain cancer in some special parts may have more typical early manifestations, such as temporal lobe brain cancer. Patients may show epilepsy, called epilepsy, and patients may show limb convulsions, which may be accompanied by oral foam, eyes, etc. Intracranial malignant tumors usually have no obvious symptoms in the early stage.

Can overusing your brain cause brain cancer?

The signal of overusing the brain is mental fatigue, which is the resistance of the human body, organs or major cells to continue working. The signal of fatigue indicates that the body needs rest, adjustment and recovery. Brain cancer is a malignant tumor that occurs in the skull. However, there is a situation where people who overuse their brains are prone to cerebral vascular hardening. If they have hyperlipidemia, hypertension, emotional excitement or often stay up late, they are prone to cerebral hemorrhage or cerebral infarction.

What causes coma after meningioma surgery?

Patients are often in a coma after meningioma surgery. If the time is short, it may be related to the side effects of anesthetics. After the drug is metabolized, they usually wake up gradually. If the patient is still in a coma for more than an hour more than 3~4 days after surgery, consider coma caused by intracranial hemorrhage, cerebral infarction, cerebral edema, and increased intracranial pressure. If necessary, check the head CT, and pay attention to whether it is hypoglycemia, epileptic seizures, hyponatremia, ketoacidosis, etc. Brain tumor surgery, whether it is benign or malignant tumor surgery, is performed under a microscope. Minimally invasive surgery has little trauma. If the operation is successful, the patient can wake up 6 hours after the operation. If the operation is complicated and the brain edema is severe, the patient may fall into a coma. This situation is mostly due to the complex growth site of the meningioma, located in the functional area or peripheral edema caused by malignant tumors.
