Cranial tumors, as the name suggests, are tumors that grow inside the skull and are divided into primary and secondary. Primary tumors occur in the brain tissue and its appendages inside the skull, etc. Secondary tumors are metastatic tumors formed when tumors from other parts of the body metastasize or invade the skull. Some people find brain tumors in the middle or late stage, so that they miss the best time for treatment. In fact, there are signs and symptoms of craniocerebral tumors, and the following are some signs and symptoms of early onset of brain tumors: 1. Headache: The nature of headache is more intense, often occurring in the early morning, and sometimes occurring in the sleep so that the patient is woken up by the pain; however, after getting up and doing light activities, the headache will be relieved or disappeared gradually. 2. 2, vomiting due to the increase in intracranial pressure, resulting in the vagus nerve center is stimulated, resulting in vomiting, vomiting more in the headache after the emergence of jet. 3.Loss of vision When the intracranial pressure increases, the venous blood of the eyeballs will not return smoothly, resulting in bruising and edema, damaging the visual cells on the retina at the bottom of the eye, resulting in loss of vision. 4, mental abnormality Brain tumor located in the frontal lobe of the anterior part of the brain can destroy the mental activities of the frontal lobe, causing mental abnormalities such as excitement, agitation, depression, depression, forgetfulness, fiction and so on. Epileptic seizure 6. Sensory and motor abnormality of one side or one side of limb The parietal lobe located in the middle of cerebral hemisphere is specialized in sensory control, and the tumor in this part of the brain may lead to unilateral loss or disappearance of pain, warmth, vibration, and physical discrimination of limb. 7, Phantom smell The temporal lobe tumor may appear phantom smell under its stimulation, that is, it can smell a kind of non-existent smell, such as burnt rice or burnt rubber smell. Hemiplegia or drunken gait. Cerebellar lesions are more specific, i.e., patients often have hemiplegia or staggering drunken gait after headache, vomiting and visual impairment. 9, tinnitus, deafness: this kind of mostly found in the phone call, that is, one ear can hear, the other ear can not hear, the performance is mostly a precursor of the auditory neuroma. 10, gigantism or dwarfism: gigantism is mostly seen in pituitary tumor, which is manifested as rapid growth of the patient and the emergence of acromegaly (big chin, big nose, lips, tongue are enlarged, and hands and feet are abnormally large).
