What are the symptoms of advanced lung cancer brain metastasis? 8 common symptoms of advanced lung cancer brain metastasis

Lung cancer is a very common cancer disease, which is more common in middle-aged men. The reason why there are more male patients is mainly because male friends love to smoke. Frequent smoking will have a great impact on the lungs, which will lead to lung cancer. If you have lung cancer, you must treat it in time. If lung cancer patients do not go to the hospital for treatment in time, it will easily lead to cancer cell metastasis. So what are the symptoms of brain metastasis in the late stage of lung cancer?

(1) Mental abnormalities: Brain tumors located in the frontal lobe of the brain can destroy the mental activities of the frontal lobe, causing abnormal mental manifestations such as excitement, depression, agitation, depression, amnesia, and fabrication.

(2) Olfactory hallucinations: Temporal lobe tumors may cause olfactory hallucinations, where a person smells an odor that does not exist, such as burnt rice or burnt rubber.

(3) Headache: The headache is usually severe and often occurs in the early morning. Sometimes the patient will be awakened by the pain during sleep, but the headache will gradually ease or disappear after getting up and doing some light activities.

(4) Hemiplegia or staggering gait: Because lesions in the cerebellum are more specific, even patients often experience hemiplegia or a staggering gait like a drunk after having a headache, vomiting, or visual impairment.

(5) Unilateral limb paresthesia or weakness: The parietal lobe, located in the middle of the cerebral hemisphere, is responsible for sensation. Malignant tumors in this area often lead to decreased or absent sensations of pain, temperature, vibration, and body shape in one side of the limb.

(6) Tinnitus and deafness: This is often found when making a phone call, that is, one ear can hear but the other ear cannot. This symptom is often a precursor to acoustic neuroma.

(7) Visual impairment: When intracranial pressure increases, the venous blood return to the eyeball will be blocked, leading to congestion and edema, damaging the visual cells on the retina of the fundus, and causing decreased vision.

(8) Vomiting: Due to the increase in intracranial pressure, the respiratory center in the medulla oblongata is stimulated, resulting in vomiting. Vomiting often occurs after a headache and is in the form of a jet.

For lung cancer patients, it is not possible to not treat it. Although lung cancer has little impact on the patient's health in the early stage, if it is not treated in time, the cancer cells will metastasize and seriously endanger life safety. Therefore, experts remind fellow lung cancer patients that they must be diagnosed and treated in time so that they can see the effect.
