What are the most common symptoms of brain cancer?

People are more concerned about the symptoms of brain cancer, because brain cancer is cancer, and it can affect life if not handled with care. Therefore, people cannot neglect the importance of brain cancer. So what are the most common symptoms of brain cancer ? Let the experts answer these questions for us.

The symptoms of brain cancer in the early stages include:

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 bleeding, and blurred vision. These are symptoms of brain cancer.

3. 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.

4. 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.

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 exophthalmia: One eyeball protrudes forward. In severe cases, the eyelid does not close completely. This is also a symptom of brain cancer.

7. Mental abnormality: This symptom of brain cancer is located in the frontal lobe of the brain. The brain tumor can destroy the mental activity of the frontal lobe and cause abnormal mental manifestations such as excitement, agitation, depression, and depression.

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 is the explanation given by experts on the symptoms of brain cancer. I hope it can help you answer your questions. Experts remind that if you cannot distinguish the type of disease, the best way is to go to the hospital for examination. Do not take medicine at random according to your own will, which will worsen the condition or cause other diseases.
