Detailed analysis of the early symptoms of brain cancer

The incidence of brain cancer is very high in our country. As patients, what they want to know most is the early symptoms of brain cancer . So what are the main manifestations of the early symptoms of brain cancer? Let's take a look at the early symptoms of brain cancer.

1. Morning headache: Headache is an early symptom of brain cancer, often occurring at four or five in the morning. People are often awakened by the pain in a deep sleep. 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: 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" may occur after a headache, which are all early symptoms of brain cancer.

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 limbs. Another is unilateral limb disorder. The early symptoms of brain cancer are clumsy or unstable movements.

The above information is about the early symptoms of brain cancer. I hope it can help you. As long as we understand the early symptoms of brain cancer, we can detect the existence of the disease in time. Therefore, it is very important for us to know the early symptoms of brain cancer. Here I wish you a speedy recovery.
