Lung cancer is transferred to the brain through the blood and quietly planted in the brain. At first, there were no symptoms. The longer the tumor, the more symptoms, and lung cancer was found.
The most common symptom is dizziness and headache for many reasons. Many people will think that it is caused by cervical spondylosis and lack of sleep. At first, they didn't care, but the tumor grew rapidly and the symptoms became more and more serious. They can't stand it before they go to see a doctor.
Lung cancer is often found in the late stage, and it has often metastasized when it is found in the clinic, which is also one of the important reasons for the death of lung cancer patients. There are many ways for lung cancer to metastasize, such as directly spreading around, spreading outward through lymphatic channels, and spreading to other places through blood. And the clinical symptoms are different.
When metastatic tumors of lung cancer grow in different parts of the brain, they will show many different symptoms. First of all, there may be unexplained headaches, vomiting, and changes in personality and temper, which may be symptoms of intracranial hypertension caused by lung cancer metastasis to the brain. As the name implies, the pressure inside the skull is too great for the brain tissue to bear. Some people take headache as the most common symptom, and vomiting mostly occurs when the headache is severe, showing jet vomiting.
Lung cancer has spread to the brain. When the lesion is small, there may be no symptoms. When the lesion is small, there may be no symptoms. Some patients find brain metastases when they regularly check MRI or PET-CT. When the metastatic focus grows to a certain size or occurs frequently, increased intracranial pressure's symptoms are caused by the occupying effect.
It is characterized by headache, vomiting and nipple edema. In fact, this is not only brain metastasis of lung cancer, but also brain metastasis of other tumors or intracranial primary tumors may have symptoms of increased intracranial pressure. Multiple brain metastases can induce abnormal brain discharges and cause seizures, also known as secondary epilepsy.
When there are many metastases, the intracranial pressure is too high, which may lead to consciousness disorders, such as lethargy, lethargy, coma, and even life-threatening cerebral hernia. Some patients with lung cancer have meningeal metastasis, which may not be seen on ordinary CT or even MRI. In order to make a definite diagnosis, it is necessary to perform lumbar puncture to check cerebrospinal fluid.
Brain tumors will have local edema and secondary intracranial hypertension, so there will be vomiting and nausea. Brain tumors will have local edema and secondary intracranial hypertension, so there will be symptoms such as vomiting, nausea, headache and mental abnormality. In addition, according to the different parts of tumor growth, there will be different symptoms, such as hemiplegia, loss of appetite, mental abnormality, dyskinesia, limb tremor, dizziness and so on. This has a lot to do with the location of tumor growth.
The symptoms of brain metastasis of lung cancer are mainly related to the location of metastatic tumor. Metastasis of cerebellum is mainly dizziness and unsteady walking, while metastasis of brain parenchyma is mainly headache and dizziness. Severe brain edema and increased intracranial pressure will be accompanied by nausea and vomiting, and tumors in the brain stem will even directly cause respiratory and cardiac arrest.
Brain metastasis is the most common cause of death in lung cancer. Therefore, when the tumor is small and the lesions are few, surgical resection or gamma knife treatment can be considered, which can effectively alleviate the disease and prolong the survival time.
Brain metastasis of lung cancer is prone to bleeding, sudden massive cerebral hemorrhage, sudden coma and loss of consciousness. Brain metastasis of lung cancer is prone to bleeding, sudden massive cerebral hemorrhage, sudden coma and loss of consciousness. In addition, there may be emotional and behavioral changes, vomiting, hemiplegia, blurred vision, aphasia, muscle weakness and other symptoms. When patients with lung cancer are found, they usually have a head CT examination to see if there is metastasis.
But sometimes CT can't see tiny metastases, so magnetic resonance is very sensitive to tiny metastases, especially enhanced scanning, which can find many metastases that CT can't see. In addition to brain metastasis, lung cancer is prone to adrenal metastasis, which is also related to the blood system. Early lung cancer can be found and treated as soon as possible, and brain metastasis can be killed in the cradle. Especially those who have a history of smoking and a family history of cancer should pay more attention to physical examination.
