What are the symptoms of brain metastasis from lung cancer? If lung cancer patients have these symptoms, it means brain metastasis

The appearance of lung cancer will undoubtedly cause a great blow to patients, because it is a very serious disease. Moreover, lung cancer may also metastasize to the brain, and in this case, the harm caused will be greater. So, what are the symptoms of lung cancer brain metastasis? Now, patients, let's take a look at the introduction of this article.

Lung cancer patients experience headaches, vomiting, visual disturbances, and personality and temper changes without cause. Most of these are caused by tumor metastasis to the brain, which causes intracranial hypertension or damage to cranial nerves. This is common in small cell lung cancer and adenocarcinoma. Headache is the most common symptom. Usually, the symptoms of lung cancer brain metastasis are as follows:

Olfactory phantom: Under the stimulation of temporal lobe tumors, lung cancer patients may experience olfactory phantom, that is, they can smell an odor that does not exist, such as burnt rice or burnt rubber.

Tinnitus and deafness: When patients are on the phone, they often feel that they can hear with one ear but not with the other ear. This is also a sign of auditory brain metastasis compressing the nerves.

Visual impairment: When intracranial pressure increases due to brain metastasis, the venous blood return to the eyeball will be blocked, causing congestion and edema, which can damage the retina and cause decreased vision in lung cancer patients.

Mental abnormalities: Brain tumors that metastasize to the frontal lobe of the brain can destroy the mental activities of the frontal lobe, causing lung cancer patients to have abnormal mental symptoms such as excitement, agitation, depression, repression, amnesia, and fabrication.
