What are the signs of brain cancer

The early symptoms of brain cancer patients are usually not very typical and can manifest as a mild headache. If the condition worsens, the patient's headache will become more severe, or it will worsen intermittently on the basis of a continuous headache, which will be more obvious when the patient exerts force. As the disease progresses, the patient may feel nauseous or even vomit. For some brain cancers that occur in special parts, the patient's early manifestations may be more typical. For example, brain cancer occurring in the temporal lobe can manifest as epilepsy, which is what ordinary people call epilepsy. The patient may show limb spasms, accompanied by foaming at the mouth, eyes rolling up, etc. Patients with early brain cancer that appears in the motor area may also show numbness and weakness of one limb. Severe patients may have hemiplegia. For brain cancer occurring in the visual center, the patient may have partial blindness in the field of vision of the eye.

Brain cancer is a popular term, but it is not entirely correct. In the field of neurosurgery, it mainly refers to neuroepithelial tumors and gliomas with higher malignancy. The early symptoms of this malignant tumor mainly include symptoms of neurological deficits, symptoms of neurological release, and symptoms of neurological irritation. If the tumor is located in the functional area, motor and sensory disorders of the contralateral limbs may occur. If the tumor causes upper motor neuron paralysis, it is likely to occur, and muscle tension will increase. If the tumor is an irritating lesion, epilepsy is likely to occur.

The symptoms of brain tumors can be roughly divided into two categories: the first category is general symptoms and signs, which have no direct correlation with the location of the tumor, mainly including headache, vomiting, visual impairment, dizziness, epilepsy, diplopia, mental and consciousness disorders, etc. Children may also have abnormal enlargement of the head. About 1/3 of brain tumor patients may experience epilepsy. The second category is local symptoms with positioning significance, and the appearance of symptoms is related to the growth site of the tumor. Patients with frontal lobe tumors usually have psychiatric symptoms such as euphoria, indifference, alienation, poor orientation, memory loss and poor appearance. Patients with parietal lobe tumors may have contralateral deep and shallow sensation and cortical sensory disorders, or local sensory epilepsy. Temporal lobe tumors can cause contralateral homonymous hemianopsia, hallucinations, temporal lobe epilepsy and psychiatric symptoms.
