The general survival time after surgery for malignant tumors of the brain is between 0.5 and 2 years, but it is also important to be aware of the changes in your condition. In some cases, after active treatment, the survival time may be more than 2 years. And some may only have a survival time of about 3 months without active treatment, so there’s a lot of variability here. And now with the continuous advancement of technology, not only surgery can remove most tumors, but also radiotherapy, chemotherapy, molecular targeted therapy and various other modalities can go in combination to treat malignant tumors in the brain. Therefore, no matter whether surgery is performed or not, all kinds of treatments should be combined in time at the later stage in order to kill the tumor cells as much as possible and restore a relatively healthy state. Therefore, for malignant tumors of the brain, what should be done is not to cure but to reduce the pain of patients and prolong the survival time of patients as much as possible.
