The incidence of brain tumor is relatively high, and malignant tumor is also more common, it is because of the untimely detection that brings difficulty to the treatment. 1. Early morning headache: headache often occurs at four or five o’clock in the morning, often waking up in the middle of sleep, so it is called “early morning headache”. 2. Jet vomiting: Compared with vomiting in gastrointestinal diseases, vomiting in brain tumor patients is not accompanied by gastric distension, nausea, abdominal pain and diarrhea. The vomiting is not related to eating, but occurs suddenly after a headache. 3.Visual impairment: After brain tumor causes brain pressure increase, poor blood flow in eye veins leads to stagnation and edema, which can damage the visual cells on retina in the fundus of the eye and cause vision loss. Some patients show an incomplete range of visual field defects. 4. Monocular protrusion: i.e., one side of the eye protrudes forward, leading to incomplete eyelid closure in severe cases. 5.Phantom smell: The appearance of phantom smell is due to the stimulation of the tumor in the temporal lobe of the lower part of the brain. Patients often smell odors that do not exist, such as the smell of burning rubber, burnt rice or incense. 6. Transient loss of recognition: People with temporal lobe brain tumor may also have a sense of strangeness and déjà vu, which can occur for several minutes. 7. Hyperalgesia: A tumor in the parietal lobe, located in the middle of the cerebral hemisphere, can cause a variety of sensations in the contralateral hemisphere – pain, heat and cold, touch, vibration and shape discrimination. 8. Unilateral deafness: If there is no history of otitis media and only one side of the ear shows hearing loss, it is likely to be caused by intracranial tumor compressing the auditory nerve. Late onset epilepsy. If epilepsy starts to occur after adulthood, brain tumor should be considered first if there is no other causative factor. If you have the above symptoms, you should consult the neurosurgery department of a regular medical institution for further examination as soon as possible. Common examinations include CT, MRI and PET-CT. Once brain tumor is diagnosed, the surgical plan should be made according to the location and type of tumor in the skull.
