How does brain cancer metastasize

The best time to treat cancer is in the early stage when cancer cells have not metastasized or spread. Treatment during this period can achieve the best effect of curing cancer. However, due to the hidden nature of brain cancer, the symptoms of early brain cancer patients are extremely subtle. Clinically, it has been found that most brain cancer patients have already reached the middle and late stages when they show obvious symptoms. Here, we remind all friends who are concerned about brain cancer to pay attention.

Symptoms of Brain Metastases

Due to the rapid growth of the tumor and severe edema around the brain, the symptoms of increased intracranial pressure appear early and significantly. About 90% of patients have headaches, about 70% have nausea and vomiting, more than 70% have papilledema, 30% to 40% have fundus hemorrhage, about 20% have visual impairment, 15% have abducens nerve palsy, and about 15% of patients have varying degrees of impaired consciousness in the late stage. The general condition of the patients is mostly poor, and some are significantly emaciated. About 20% of patients have epileptic seizures, most of which are localized.

Since brain metastases occur when the primary tumor cannot be effectively controlled after comprehensive treatment such as surgery, radiotherapy and chemotherapy, and are often multiple, it is difficult to suppress them with surgery, radiotherapy and chemotherapy, and the clinical effect is not ideal. In addition, surgery is not suitable for patients whose primary tumor cannot be removed, have multiple metastases in the body, and are in very poor general condition. In this case, biological immunity can be used for treatment.

Biological immunotherapy for brain cancer

The latest biological cell immunotherapy for brain tumors is currently the most effective and safest auxiliary treatment method. Cell immunotherapy, surgical treatment, chemotherapy and radiotherapy can be used together to have a strong complementary effect. It can restore and rebuild the patient's damaged immune system: it can prevent tumor recurrence and metastasis when used in conjunction with surgical treatment; it can prolong life when used together with chemotherapy; and it can improve the patient's quality of life.

So far, the international application of biological immunotherapy for kidney cancer has matured. In clinical applications, international clinical trials of biological immunotherapy for kidney cancer have shown that biological immunotherapy can effectively inhibit and kill tumor cells without adverse side effects. In particular, it plays an important role in removing residual tiny metastatic lesions for tumor patients after surgery, preventing the spread and recurrence of cancer cells, and improving the patient's own immunity. The killing activity of cancer cells in the treatment of liver cancer, kidney cancer, breast cancer, gastric cancer, colorectal cancer, ovarian cancer, etc. is as high as 60%-90%. In addition, this therapy has no obvious toxic and side effects and risks.

The above is a brief introduction to "What are the symptoms of late-stage brain cancer metastasis?" For people who are related to the pathogenic factors of brain cancer, it is recommended to take preventive measures for brain cancer and carry out specific treatment according to the doctor's instructions. I hope that patients can recover soon! If you have other questions about brain cancer, please consult our experts online or call for consultation.
