Several common early symptoms of brain cancer in life

Brain cancer refers to a new growth in the cranial cavity, also known as an intracranial tumor. Many patients miss the best time for treatment because they do not understand the early symptoms, which makes subsequent treatment difficult. Let us now learn about the early symptoms of brain cancer .

1. Morning headache: Headache is a common early 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: 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 occur after a headache. This is an early symptom 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 at the bottom 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. This is also an early symptom of brain cancer.

The above is an introduction to the early symptoms of brain cancer. I hope the above content can be helpful to you. If you find yourself having the above symptoms, you must pay attention to it. It is best to go to a regular hospital for examination. If confirmed, timely treatment is required.
