Brain tumor is a very terrible tumor with a high incidence, and the number of patients with brain tumors reached 320,000 people. Many people worry that they have a brain tumor as soon as they have a headacheWhat are the symptoms of a brain tumor?
Frequent headaches are brain tumors
Brain tissue is trapped in a closed cranial cavity, and if a new organism (brain tumor) the size of a broad bean grows on the brain tissue, it will inevitably occupy a certain space, and as it grows larger, the brain tissue will inevitably be squeezed and displaced, causing headaches. If the new organism grows in the posterior fovea (eg, cerebellar tumor) or in a pathway of cerebrospinal fluid circulation, which quickly obstructs cerebrospinal fluid circulation and causes a rapid increase in intracranial pressure, headache becomes an early and prominent symptom.
Brain tumors grow on the frontal lobe of the brain, which is the wisdom area of the human being, which has no important nerves and is far away from the cerebrospinal fluid circulation channel, which is the "Pu area" in medicine. Therefore, some patients have headaches and paralysis of the limbs that are not obvious, but are characterized by laziness or euphoria, emotional apathy, and unkemptness.
It can be seen that although headache is a common symptom of brain tumor, headache may not be present in the early stage of brain tumor, mainly depending on the growth site of the brain tumor and the nature of the brain tumor. Conversely, benign meningiomas grow slowly, allowing the cranial cavity to adjust and compensate for a longer period of time, and its headache can remain unaggravated for a considerable period of time.
In addition to headaches, brain tumors also have the following symptoms, so it's best to pay more attention.
Projectile vomiting
Brain tumors are prone to projectile vomiting, which must be distinguished from gastrointestinal diseases, brain tumor patients will not be accompanied by nausea, pain, diarrhea, stomach bloating, etc., and patients will generally vomit suddenly after headache, showing projectile vomiting. This is mainly due to increased intracerebral pressure that stimulates the respiratory center of the medulla oblongata.
Visual impairment
Under normal circumstances, the blood in the veins of the eye will flow back into the brain, and when a brain tumor occurs, it will increase the cerebral pressure and the blood return of the eye vein will not be smooth, which will cause edema and damage the optic nerve on the retina, so that the vision will slowly decline. Sometimes there is a temporary blackness, and there will be a temporary visual impairment, and the more severe the disease, the vision loss will become more and more severe, and eventually lead to blindness.
Hemiparesis
There are two different conditions, one is hemiplegia or hemiplegia, which is characterized by little or no movement of the affected limb, and the other is ataxia of one limb, which is manifested by stupidity or unsteadiness. If these two symptoms occur slowly and get worse, they may be a sign of a brain tumor. The former is more common in cerebral hemisphere tumors, and the latter is a sign of cerebellar hemisphere tumors.
