Early symptoms of lung cancer brain metastasis

Early symptoms of lung cancer brain metastasis:

Early symptoms of lung cancer brain metastasis include headaches. The nature is more serious, often occurring in the early morning, sometimes waking up during sleep, but the headache will gradually ease or disappear after mild activity, vomiting. Due to the increase in intracranial pressure, the respiratory center of the medulla oblongata is stimulated, leading to vomiting. Vomiting often occurs after a headache, in the form of jets, and visual impairment. Increased intracranial pressure can cause poor venous blood return in the eyeball, leading to congestion and edema, damaging the visual cells on the retina of the fundus, and causing decreased vision.

1. Vomiting: Patients with brain metastases may experience projectile vomiting, which may be caused by increased intracranial pressure, stimulating the medullary respiratory center and ultimately causing vomiting.

2. Headache: Headache is a common symptom of brain metastasis. Severe headache may occur, usually in the early morning, sometimes waking up during sleep, but the headache will gradually ease or disappear after mild activity.

3. Mental symptoms: When the brain is transferred to the frontal lobe of the brain, it will destroy the mental activity of the frontal lobe, leading to abnormal mental manifestations such as excitement, agitation, depression, depression, amnesia, and fabrication.

4. Symptoms of visual impairment: Brain metastasis can cause poor venous blood return in the eyes, damage the visual cells on the retina, and lead to vision loss or even blindness.
