Although in recent years, domestic and foreign films and TV dramas are often about neurosurgeons or brain tumor diseases, but in general the incidence of brain tumors is relatively low compared to other parts of the tumor, so the general public for the common tumors of the brain is still relatively unfamiliar. The most common primary malignant tumors in the brain are gliomas, with the most malignant glioblastoma having a median survival time of less than two years. Although the median survival time for low-grade gliomas, which are slightly less malignant, can reach several years, it is possible for them to malignantly progress to high-grade gliomas resulting in rapid deterioration. So when a glioma happens to you, it’s natural for a patient to ask, “Why am I the one with a glioma, and what caused this?” There are two main areas of concern one is diet and the other is rest, and many people think they may be related to the occurrence of their low grade glioma. After all, too many people in modern life have unhealthy diets and work schedules that predispose them to poor concentration and even dizziness and headaches. There have also been studies that have linked specific carcinogens in certain diets to the development of specific tumors, as well as studies that have looked at the relationship between sleep, etc., and the body’s immunity, etc. But in the case of gliomas, there is no clear evidence that these factors are associated with the development of low-grade gliomas. Suffice it to say that unhealthy eating habits and irregular work schedules are certainly detrimental to health, but are not the direct cause of low-grade gliomas. Among the high-risk factors for low-grade gliomas, radiation is a relatively well-defined factor, although the carcinogenic effects of radiation on the body are relatively well-defined, and radiation exposure has been associated with the development of many types of tumors, including low-grade gliomas. In addition to radiation exposure, which is an external environmental factor associated with the development of low-grade gliomas, intrinsic genetic variants are also associated with the development of gliomas. It is true that some genetic alterations are associated with the development of low-grade gliomas, but these genetic alterations are not necessarily causally related to the development of gliomas, and it is not a given that low-grade gliomas will develop with the presence of these genetic alterations, which only increase the risk of glioma development. Patients with genetic syndromes with tumorigenic tendencies have a higher chance of developing low-grade gliomas, such as neurofibromatosis type 1, Li-Fraumeni syndrome, Lynch syndrome, Ollier syndrome, Maffucci syndrome, etc. These tumor syndromes, which are almost unheard of by the majority of the population, are associated with the development of low-grade gliomas to a certain extent, but only a very small proportion of low-grade gliomas. Although these tumor syndromes are associated with low-grade gliomas, they are only a small percentage of low-grade gliomas. Do family members of patients with low-grade gliomas get the same tumors? Current studies have found that 5-10% of glioma patients have other gliomas in their family, and some studies have shown that the incidence of gliomas in the immediate family of glioma patients is twice as high as in normal people. So the chances of a glioma patient’s immediate family members developing the same low-grade glioma are still slightly higher than the general population. What can be done to prevent low-grade gliomas? There is no particularly effective prevention method, except to say that regular head exams can help detect low-grade gliomas early. Interestingly, however, some studies have found that allergies or asthma are protective factors against gliomas, meaning that people with allergies or asthma are less likely to develop low-grade gliomas than the general population.
