Early symptoms of brain cancer can cause visual impairment

The early symptoms of brain cancer refer to malignant tumors growing in the brain. The early symptoms of brain cancer not only torture the patient's body, but also torture the patient's spirit. What are the early symptoms of brain cancer at present? Next, let the experts give us a detailed introduction to the early symptoms of brain cancer.

Headache, vomiting, visual impairment, mental abnormality, tinnitus, etc. are all early symptoms of brain cancer.

Mental abnormalities: Brain tumors located in the frontal lobe of the brain can destroy the mental activities of the frontal lobe, causing abnormal mental manifestations such as excitement, forgetfulness, depression, depression, agitation and fiction.

Unilateral limb paresthesia: This early symptom of brain cancer is located in the parietal lobe in the middle of the cerebral hemisphere, which is responsible for sensation. Tumors in this area often cause decreased or absent sensations of pain, temperature, vibration, and body shape discrimination in one side of the limb.

Vomiting: Due to the increase in intracranial pressure, the respiratory center in the medulla oblongata is stimulated, resulting in early symptoms of brain cancer such as vomiting. Vomiting often occurs after a headache and is in the form of a jet.

Visual impairment: When the intracranial pressure increases, the venous blood return of the eyeball may be blocked, causing congestion and edema, and damaging the visual cells on the retina of the fundus. Early symptoms of brain cancer can lead to decreased vision.

Hemiplegia or staggering gait: Cerebellar lesions are more specific, that is, patients often experience hemiplegia or a staggering gait like a drunken person after a headache, vomiting, or visual impairment.

Tinnitus and deafness: This early symptom of brain cancer is often found during the beating, that is, one ear can hear but the other ear cannot. Early symptoms of brain cancer are often the precursors of acoustic neuroma.
