What is the cause of death from brain cancer

The cure rate of malignant tumors has greatly improved in recent years. However, there are still a large number of patients who do not survive long, and the mortality rate is still high. In order to further improve the cure rate and reduce the mortality rate, it is necessary to study and improve treatment methods, screen new therapeutic drugs, and summarize the lessons learned from success and failure. On the other hand, it is also beneficial to study the real cause of death of cancer patients and promote the advancement of treatment measures. What is the cause of death from brain cancer?

(1) Severe infection: Infections associated with malignant tumors are quite common in clinical practice. There are three reasons for this: First, due to the continuous growth of the tumor, insufficient blood supply promotes tumor liquefaction and necrosis, forming ulcers or the tumor presses and blocks the cavity, resulting in poor excretion, which can cause infection or aggravate the infection. Second, during radiotherapy or chemotherapy, white blood cell counts often decrease, resistance decreases, and immune function decreases, which increases the chance of infection. Third, because most patients in the late stage are exhausted and have poor defense functions, they are prone to infection.
(2) Bleeding and perforation of organs: Bleeding is a common clinical symptom of cancer patients. Many patients die from heavy bleeding, such as cervical cancer, esophageal cancer, lung cancer, liver cancer, etc. Some cancer patients die from serious complications caused by perforation after ulceration of the tumor.
(3) Organ failure: Due to the growth and spread of cancer, the organ function fails and causes death. Failure of the first treatment: For cancer patients, the first treatment is very important. Some patients fail to achieve a radical cure in the first treatment. Although the purpose of prolonging life is achieved, local recurrence and extensive distant metastasis will inevitably occur after a period of time, which will bring great difficulties to the second treatment. The second treatment is often forced palliative treatment with extremely poor results. Cancer death: The so-called cancer death is due to the long-term consumption of cancer, which causes the patient to be in a state of cachexia or die due to water and electrolyte disorders.
