Usually we think that brain tumor is very far away from us, and few people can really pay attention to the harm of brain tumor in life. What are the symptoms of brain tumor in the late stage that can be easily ignored? A. Headache is not a trivial thing, especially in early morning. Generally, people usually think that headache in early morning is caused by cold, high blood pressure or staying up late, but brain tumor can also cause headache in early morning. However, brain tumors can also cause early morning headache. After the headache harasses the sleep, the headache will be relieved or disappear gradually after the person wakes up and moves a little. Early morning headache is common in posterior cranial fossa tumor, which causes pain in the occipital neck and radiates to the orbit. When brain tumor develops, it may lead to increase of intracranial pressure, obstruction of venous blood flow to the eye, resulting in bruising and edema, and damage to the visual cells in the retina of the eye, resulting in vision loss, blurred vision, or even optic nerve damage causing blindness. In addition, patients may have unilateral protrusion of the eyeball or even incomplete lid closure. Deafness should be alerted and not premature aging The earliest symptom of auditory nerve tumor is slight deafness, especially for patients who only have unilateral hearing loss. Tinnitus is also one of the attained markers of auditory nerve tumor, mostly paroxysmal. Four, smell not to eat taste Not because of nasal congestion Nasal congestion, cold will also appear this symptom from time to time, some patients will think that their cold and caused by nasal congestion, not too much attention, often delayed the treatment of the disease. In fact, this is a symptom of olfactory meningioma, which can occur in any part of the brain, and the tumor will press on any part of the brain, which part of the functional area and nerves will produce symptoms. In severe cases, some patients may even “smell” a smell that is not actually there, such as rotten egg or rubber smell. Therefore, “phantom smell” is a typical symptom for localized diagnosis of human brain tumor, and it is also one of the early signs of organic brain diseases. In addition, vomiting may also be one of the signals from brain tumor. Many people often go to gastroenterology when they vomit, but in gastroenterology, vomiting is accompanied by abdominal pain and nausea. Brain tumors are the opposite. Most of the vomiting in brain tumor patients is caused by the increase of intracranial pressure, and the most special symptom is “jet vomiting”. The most specific symptom is “jet vomiting”. Any symptom that appears in the body may be a signal from a major disease to the body. It is better to take responsibility for your own body by going to the neurosurgery department of the relevant specialized hospital in time once you are unwell!
