Metastatic brain tumors should be brain metastases, which are tumors that arise from other parts of the body that have metastasized to the brain. The most common primary site of brain metastases is lung cancer, followed by breast cancer and cancers of the digestive system such as colorectal cancer and stomach cancer.
Gradual enlargement of brain metastases will lead to increased intracranial pressure, such as headache, blurred vision, projectile vomiting, etc. Some patients will also suffer from limb movement disorder, meningeal irritation and mental symptoms.
The main auxiliary examinations for brain metastases include CT and MRI examination of the head. The treatment methods for patients with brain metastatic tumor include radiation therapy, anti-cancer drug therapy, surgery and so on.
The prognosis of patients with brain metastases is generally poor, and most of them will die within months or even weeks if they do not receive treatment. For different patients, appropriate treatment measures should be taken in time, which can prolong the survival time and improve the quality of patients’ survival.
