Because brain tumor is not easy to judge, many people have uncomfortable symptoms for a long time without getting attention, which delays the best time for treatment. We will introduce several symptoms related to brain tumor to you. 1.Headache after waking up: Generally, headache can be relieved after afternoon, but not for brain tumor, the headache is often the heaviest when waking up after a night’s sleep, and will be gradually reduced after getting up. 2. Jet vomiting: usually occurs when the headache is severe, and the headache can be relieved after vomiting. 3.Loss of vision: Early on, it can be a momentary black film with transient loss, which gradually becomes persistent vision loss with the aggravation of the disease and finally may be completely blind. 4, diplopia: that is, the two eyes cannot overlap together in imaging, see any object in double shadow. At first, diplopia can only appear when the eye is gazing in a certain direction, but later it can develop to appear in any direction, and finally when the position of both eyes has been significantly asymmetrical, diplopia may be reduced or even disappear. 5.Visual field defect: usually shows bilateral temporal hemianopia, which can hinder the patient’s behavior in severe cases. 6, monocular protrusion: that is, one side of the eye protrudes forward, and in severe cases, it may affect the incomplete closure of the facial fissure. In 50% of cases of unilateral eye protrusion, it is caused by intracranial disorders, and the most common cause is brain tumor. 7. Unilateral deafness: If middle-aged people have no history of otitis media or trauma and only have progressive hearing loss with or without ipsilateral tinnitus, most of them are caused by tumor compression of the auditory nerve. 8.Late onset epilepsy: It refers to those who start to have seizures after adulthood. If there is no trauma and other causative factors, intracranial tumor should be considered first. If the convulsive seizures are limited to one side or started by a limb, brain tumor should be considered in both adults and children. 9. Hemiplegia: It includes two different conditions, one is hemiplegia or hemiparesis, which shows little or no movement of the limb on the diseased side, and the other is ataxia of one limb, which shows clumsy or unstable movement. Both of these symptoms may be signs of brain tumor if they appear slowly and get progressively worse. The former is mostly seen in cerebral hemisphere tumors, while the latter is a sign specific to cerebellar hemisphere tumors. 10. Acromegaly: It is a unique clinical sign of eosinophilic pituitary tumor, which is seen in adult onset. Amenorrhea and lactation: Amenorrhea and lactation in women of childbearing age are often the first symptoms of pituitary tumors. Men mainly show impotence and loss of pubic hair, axillary hair and beard, and thickening of subcutaneous fat.
