What are the advanced symptoms of lung cancer brain metastasis? 7 advanced symptoms of lung cancer brain metastasis

Lung cancer is a common and very harmful disease. Once lung cancer metastasizes to the brain, it will cause great pain to the patient. In life, people often have misunderstandings about the "late-stage symptoms of lung cancer brain metastasis", which brings certain difficulties to the treatment of patients. In order to help lung cancer patients get better treatment, experts have made relevant introductions.

The main symptoms of advanced brain metastasis of lung cancer are as follows:

1. Headache: Headaches are often severe and often occur in the early morning. Patients usually wake up in pain during sleep.

2. Vomiting: Because the patient's intracranial pressure increases, vomiting often occurs.

3. Visual impairment: Visual impairment is a more obvious symptom of late-stage brain metastasis of lung cancer. When intracranial pressure increases, venous blood return to the eyeball is often blocked, visual cells are damaged, and vision is eventually impaired.

4. Mental abnormalities: If the tumor destroys the mental activities of the frontal lobe, it will often cause the patient to experience mental abnormalities such as excitement, agitation, depression, etc.

5. Unilateral limb paresthesia or weakness: Patients with brain metastasis of lung cancer often eventually experience decreased perception of pain, temperature, vibration, etc. in one side of the limb.

6. Olfactory hallucination: Lung cancer patients often smell an odor that does not exist at all.

7. Hemiplegia or staggering gait: Hemiplegia or staggering gait is also a common symptom of late-stage brain metastasis of lung cancer.
