Are painkillers useful for brain cancer?

The use of painkillers in the later stages of brain tumors cannot achieve the analgesic effect, because the pain of brain tumors is caused by the size of the tumor and surrounding edema, or compression of normal brain tissue, which leads to increased intracranial pressure. The best treatment is surgical resection or the use of dehydration drugs to reduce intracranial pressure. This is because the patient's brain tumor has a space-occupying effect, which leads to increased intracranial pressure. The increase in brain pressure is more obvious when the patient is in the supine position, so the patient's headache may be further aggravated when lying in bed compared to the upright position. If the patient is diagnosed with a brain tumor and has pain, it is best to follow the three-step analgesia principle.

Will people with brain cancer have a high fever?

Brain tumor patients will have a fever, because the main symptoms of patients are dizziness and headache. Nausea and vomiting are caused by increased intracranial pressure. Because brain tumor patients are relatively weak and have low resistance, intracranial malignant tumors include gliomas, malignant meningiomas, germ cell tumors, etc. As the tumor grows, it will cause symptoms of increased intracranial pressure. If there is a concurrent intracranial infection, it will cause fever. If it causes damage to the hypothalamus, it can lead to abnormal temperature regulation. Treatment should be carried out in a timely manner according to the specific symptoms. In general, the possibility of brain cancer causing fever is relatively small, but it cannot be completely denied.

What are the symptoms of cancer metastasis to the brain?

Most brain metastases can cause increased intracranial pressure and aggravated cerebral edema, leading to headaches and dizziness in patients. In severe cases, patients may experience hemiplegia and blurred vision. The symptoms of brain metastasis mainly include the following aspects: headache, vomiting, papilledema, hemiplegia, and movement disorders. The probability of lung cancer metastasis to the brain is approximately 40%. The symptoms vary depending on the location and size of the brain metastasis.
