What are the symptoms of mid-stage brain cancer?

1. Headache: The headache is usually severe and often occurs in the early morning. Sometimes the patient wakes up from sleep with pain, but the headache will gradually ease or disappear after getting up and doing some light activity.

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

3. Visual impairment: When the intracranial pressure increases, the venous blood return of the eyeball may be blocked, causing congestion and edema, damaging the visual cells on the retina of the fundus, and causing decreased vision.

4. Mental abnormalities: Brain tumors located in the frontal lobe of the brain can destroy the mental activities of the frontal lobe, causing mental abnormalities such as excitement, agitation, forgetfulness, depression, fabrication and so on.

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

6. Olfactory hallucination: Tumors in the temporal lobe may cause olfactory hallucinations, that is, the smell of an odor that does not exist, such as burnt rice or burnt rubber.

7. Hemiplegia or staggering gait: Cerebellar lesions are more specific, that is, patients often experience hemiplegia or staggering gait of drunkenness after headache, vomiting, and visual impairment.

8. Tinnitus and deafness: This is often found when making a phone call, that is, one ear can hear but the other ear cannot. This symptom is often a precursor to acoustic neuroma.

9. Gigantism: It is often seen in pituitary tumors. The patient grows rapidly and develops acromegaly (large chin, big nose, enlarged lips and tongue, and abnormally large hands and feet).
