Tumors located in the skull are often referred to as brain tumors by patients, but there are dozens of hundreds of brain tumors according to accurate pathological typing. Not only are different types of brain tumors treated differently, but even for the same type of tumors, because of the characteristics of the tumors themselves and the patient’s individual differences, the treatments may also be completely different. Although the treatment methods are very different, the general principle is to maximize the survival time of the patient and improve the quality of life of the patient, to put it in simple words, to let the patient live a long life, but also to live well. When talking with patients about their conditions, we often hear people say, “Our next-door Wang, diagnosed with a brain tumor, did not treat anything, and now he is still alive and well, so why should I have surgery for this”. Or “Old Li in our village died soon after the brain tumor surgery, is there any point for me to have the surgery”. However, because different brain tumors have different impacts on the body, different patients have different physical conditions, and surgery is a traumatic treatment, so some brain tumors that have little impact and harm can only be closely observed, while brain tumors that are more harmful to the body must be actively dealt with and even surgically removed. There were two such patients in this outpatient clinic, one of them was a middle-aged male in his 50s, who accidentally found a meningioma less than 2cm in size in the left temporal region. For the time being, this small meningioma did not have any impact on his life. Moreover, the diagnostic accuracy of MRI for this kind of typical meningioma is relatively high, and most of these meningiomas are benign and grow slowly, and some may not even grow for a period of time, so it is very unlikely that this small meningioma will jeopardize the patient’s health for a long period of time in the future. On the other hand, surgery is also traumatic and risky, and is of little value to him at this time. Therefore, this patient’s brain tumor does not need to be resected, and regular follow-up MRI observation is enough, even if the tumor grows and endangers his health in the future, it is not too late to consider surgery again. Of course, not all meningiomas are suitable for observation, and many meningiomas need to be surgically removed. Another woman’s symptoms did not seem serious on the surface, but she actually had a mild headache. The MRI showed a relatively large tumor in the right frontal lobe of the brain, and the preliminary diagnosis of malignant glioma was more likely. Although this brain tumor currently has a relatively small impact on the patient’s life, but because the tumor volume has been relatively large, will soon seriously affect the patient’s physical health, and is fatal harm. At the same time, because it is likely to be a malignant tumor, it is necessary to avoid further damage to the brain tissue by the tumor after surgical removal of the brain tumor, and at the same time, to make a clear diagnosis through the tumor tissue obtained by surgery, to start the follow-up treatment and to prolong the patient’s life. Therefore, even though surgery is traumatic and risky, the benefits outweigh the disadvantages for this lady, not only does she need surgery, but the sooner the surgery is performed the better the outcome for her. The specificity and complexity of brain tumors make the management of different brain tumors in different patients may be very different, according to the actual situation of each patient’s brain tumor, individualized treatment plan, in order to get the best treatment results.
