What are the complications of brain cancer

What are the complications of brain cancer? When the disease of patients with malignant brain cancer develops to a certain extent, metastatic lesions will appear in other parts of the body, and some complications will also occur. The occurrence of complications will further reduce the quality of life of patients. Clinically, the most common complication of malignant brain cancer is the occurrence of intracranial metastases. The following is a detailed introduction to the occurrence of intracranial metastases.

Intracranial metastasis (also known as brain metastasis) refers to tumor cells originating from other parts of the body that have metastasized into the brain. Its incidence accounts for a portion of intracranial tumors. Both domestic and foreign experts believe that lung cancer brain metastasis is the most common, followed by melanoma, urogenital tumors, and digestive tract tumors. A considerable number of patients cannot find the primary lesion. Even if there is brain metastasis, the source of the tumor cannot be determined after surgery. The peak age of onset is 40-60 years old, and there are more men than women.
Brain metastatic tumor cells often metastasize to the brain through the bloodstream, subarachnoid space, lymphatic system or direct invasion. The location of the tumor is related to the blood supply and tissue volume of the affected area. It is more common in the brain substantia, and metastases to the meninges and skull can also be seen. According to its pathological characteristics, it is divided into nodular type and diffuse type.
Clinical manifestations of brain metastases: Brain metastases can show symptoms and signs at any time after the primary tumor. Generally, lung cancer, melanoma and gastric cancer metastasize to the brain early, while breast cancer, sarcoma and other gastrointestinal tumors metastasize to the brain later.
