What are the symptoms of brain metastases?
Brain metastases are secondary tumors that form when malignant tumors in other parts of the body spread to the brain through the blood or lymphatic system. In recent years, as the incidence of cancer has increased, the number of brain metastases has also gradually increased. Understanding the symptoms of brain metastases is critical for early detection and treatment. This article will combine the hot topics and hot content on the Internet in the past 10 days, introduce the symptoms of brain metastases in detail, and present relevant information through structured data.

| Symptom Category | Specific performance | Possible reasons |
|---|---|---|
| Headache | Headache that persists or gets worse, especially in the morning | Increased intracranial pressure or tumor compression |
| Nausea and vomiting | Nausea and vomiting associated with headache, especially projectile vomiting | Increased intracranial pressure stimulates the vomiting center |
| neurological dysfunction | Limb weakness, numbness, difficulty speaking, blurred vision | Tumor compresses or invades functional areas of the brain |

| Brain MRI | surgical resection | Solitary or resectable tumor |
| Head CT | Radiation therapy (whole brain or stereotaxic) | Multiple or inoperable tumors |
| PET-CT | targeted therapy | Tumors with specific genetic mutations |
| cerebrospinal fluid examination | Immunotherapy | Some immune-sensitive tumors |
