brain metastases from lung cancer
Introduction
Introduction to lung cancer brain metastasis Lung cancer brain metastasis is a common and serious condition in the clinic, and it is also one of the common causes of lung cancer treatment failure. About 20% of patients with small cell lung cancer have brain metastases at the time of diagnosis, and the incidence of brain metastases in autopsy of small cell lung cancer patients is as high as 80%. About 30% of patients with non-small cell lung cancer have brain metastases in the course of the disease. Among them, large cell undifferentiated carcinoma and adenocarcinoma are more common, followed by squamous cell carcinoma. basic knowledge Sickness ratio: 0.0001% Susceptible people: no special people Mode of infection: non-infectious complication:
Cause
Causes of lung cancer brain metastasis
Causes of lung cancer brain metastasis: This is because there is a large number of anastomotic branches between the cerebral blood vessels and the vertebral artery and the static arterial plexus supplying the brain, so that the lung cancer cells can pass through the heart, the carotid artery and the brain without filtering through the pulmonary capillaries. And blood transfer occurs. Headache, vomiting, visual impairment, and personality and temper changes in patients with brain metastases from lung cancer may be caused by intracranial hypertension or damage to the brain caused by lung cancer metastasis to the brain.
Prevention
Lung cancer brain metastasis prevention
Lung cancer patients with unexplained headaches, vomiting, visual impairment, and personality and temper changes may be caused by intracranial hypertension or damage to the brain caused by lung cancer metastasis to the brain. Early detection and early diagnosis and early treatment.

Symptom
Brain metastasis symptoms of lung cancer Common symptoms Tinnitus and vomiting visual impairment
(1) Headache. The nature is more intense, often in the morning, sometimes awakened during sleep, but the headache will gradually ease or disappear after getting up with mild activity.
(2) Vomiting. Due to the increase of intracranial pressure, the medullary respiratory center is stimulated, resulting in vomiting. Vomiting occurs after the headache and is sprayed.
(3) Visual impairment. When the intracranial pressure is increased, the blood flow of the ocular venous blood will be poor, resulting in congestion and edema, damage to the visual cells on the retina of the fundus, resulting in decreased vision.
(4) Mental abnormalities. Brain tumors located in the frontal lobe of the brain can destroy the mental activity of the frontal lobe, causing mental abnormalities such as excitement, agitation, depression, depression, forgetting, and fiction.
(5) Unilateral limbs are abnormal or weak. The parietal lobe, located in the middle of the hemisphere of the brain, is dedicated to the perception that tumors in this area often cause unilateral limb pain, temperature, vibration, and loss of body shape or disappearance.
(6) Magical smell. The temporal lobe tumor can be scented under its stimulation, and it can smell a non-existent odor, such as burnt rice or coke rubber.
(7) Hemiplegia or gait: The cerebellar lesion is more specific, that is, the patient often has a hemiplegia or paralysis drunken gait after headache, vomiting, and visual disturbance.
(8) Tinnitus and deafness. This kind of more is found when making a call, that is, one ear can hear, the other ear can not hear, and the performance is mostly a precursor to acoustic neuroma.
Examine
Examination of lung cancer brain metastasis
The manifestations of lung cancer brain metastases are diverse, so when the above signs appear, they should go to the hospital for detailed examination. At present, computed tomography (CT) and magnetic resonance imaging (MRI) can make accurate diagnosis for brain metastases at an early stage. In particular, MRI is recommended.
