What are the early symptoms of brain cancer

Brain cancer is a malignant tumor in the brain. The mortality rate of this disease is very high. So far, the cause of brain cancer has not been thoroughly studied. Do you know what the early symptoms of brain cancer are? Here are some early symptoms of brain cancer.

1. Morning headache: Headache is a common symptom of brain cancer, often occurring at four or five in the morning. People are often awakened by the pain while sleeping. The headache gradually eases or disappears after getting up and doing some light activities, so it is called "morning headache". Tumors in the posterior cranial fossa can cause neck pain that radiates to the eye sockets, and the severity of the headache gradually increases as the disease progresses.

2. Visual impairment: Increased intracranial pressure can cause edema due to poor venous blood return to the brain, leading to decreased vision. In severe cases, the retina may have punctate, linear, or flaky lesions or even hemorrhage, causing blurred vision.

3. Projectile vomiting: Brain cancer is a malignant tumor in the brain, and the mortality rate of this disease is very high. So far, the cause of brain cancer has not been thoroughly studied. Do you know what the early symptoms of brain cancer are? Here are some early symptoms of brain cancer.

Tumors in the posterior cranial fossa can cause neck pain that radiates to the eye sockets, and the severity of the headache gradually increases as the disease progresses.

2. Visual impairment: Increased intracranial pressure can cause venous blood in the eye to flow back to the brain and cause edema, leading to decreased vision. In severe cases, there are punctate, linear, or flaky lesions or even bleeding in the retina of the fundus, causing blurred vision.

3. Projectile vomiting: Compared with vomiting caused by gastrointestinal diseases, vomiting in patients with brain cancer is not accompanied by abdominal distension, nausea, or diarrhea. However, when intracranial pressure increases, "projectile vomiting" symptoms will appear after a headache.

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, depression, and depression.

5. Olfactory hallucinations: Olfactory hallucinations occur because the temporal lobe located in the lower part of the brain is stimulated by the tumor. Brain cancer patients often smell odors that do not actually exist, such as burning rubber, burnt rice, etc.

6. Monocular exophthalmos: One eyeball protrudes forward. In severe cases, the eyelid does not close completely. The most common cause is a brain tumor.

7. Decreased sensation: The parietal lobe located in the middle of the cerebral hemisphere is responsible for sensation. Brain cancer in this area can cause decreased or absent sensations such as unilateral limb pain and body shape discrimination.

8. Unilateral deafness: If there is no history of otitis media or trauma, and only one ear has progressive hearing loss, accompanied by tinnitus on the same side, it is likely caused by an intracranial tumor compressing the auditory nerve.

9. Hemiplegia: One is weakness or hemiplegia of one side of the body, which is manifested by less movement or immobility of the affected limb. The other is limb disorder on one side, which is manifested by clumsy or unstable movements.

The above are the early symptoms of brain cancer. Experts suggest: If you have symptoms of disease, do not delay diagnosis and go to a regular hospital for treatment in time to avoid delaying the disease and causing serious consequences.
