People will suffer from early symptoms of brain cancer

Have you heard of brain cancer? I believe many people have heard of brain cancer. It is also a major cancer disease. So, what are the early symptoms of brain cancer ? Let's learn about it from the following article.

1. Visual impairment is one of the early symptoms of brain cancer. Increased intracranial pressure can cause edema due to poor venous blood flow back to the brain. Brain cancer can lead to decreased vision. Severe brain cancer patients have retinal lesions in the form of dots, lines, or sheets, or even bleeding, and blurred vision.

2. Early symptoms of brain cancer may include unilateral exophthalmia, that is, one eyeball protrudes forward. In severe cases, the eyelids of brain cancer patients cannot close completely. The most common cause of brain cancer is brain tumors.

3. Brain cancer patients may experience decreased sensation. The parietal lobe, located in the middle of the cerebral hemisphere, is responsible for sensation. The early symptoms of brain cancer in this area can cause decreased or absent sensations such as unilateral limb pain and body shape identification.

4. Early symptoms of brain cancer may also include unilateral deafness. If there is no history of otitis media or trauma, only one ear will have progressive hearing loss. Brain cancer patients will also have tinnitus on the same side, which is likely caused by intracranial tumors compressing the auditory nerve.

5. Brain cancer patients may experience projectile vomiting. Compared with the vomiting of gastrointestinal diseases, the vomiting of brain cancer patients is not accompanied by abdominal distension, nausea, or diarrhea. However, when the intracranial pressure increases, "projectile vomiting" symptoms may appear after a headache.

The above is a detailed description of the early symptoms of brain cancer. I hope it can help everyone understand the knowledge of brain cancer and cure it in time. If you have other questions about brain cancer, you can contact our online experts to answer your questions.
