Will brain glioma recur once you get it?

Many patients with brain glioma who have just undergone surgery are worried that even if they are cured this time, will they relapse soon? This is also a matter of individual opinion. Some patients have good resistance and are not easily invaded by viruses, so they will not relapse after surgery. Some patients will relapse again for different reasons. The following editor will show you how to understand brain glioma. Once you have it, will it recur?

Symptoms of gliomas are usually increased intracranial pressure, headache, vomiting, optic nerve edema, visual field changes, epilepsy, diplopia, cranial enlargement (in childhood) and changes in vital signs. Currently, the treatments for gliomas at home and abroad are generally surgery, radiotherapy, chemotherapy, X-knife, gamma knife, etc.

Glioma itself is the most common malignant tumor in the brain, accounting for about 40% of intracranial tumors. The World Health Organization divides the pathological types of gliomas into four levels, among which grade I is benign glioma, grade 1-2 is low-grade malignant glioma, and grade 3-4 is highly malignant glioma. Unfortunately, grade 1 gliomas are rare, while grade 3 gliomas account for 50% of gliomas. Glioma of grades 2-3 will recur. Many patients' families find it difficult to understand the recurrence of gliomas. They think that the doctor has removed the tumor and the doctor said that it was removed very cleanly, so how could it recur? In fact, the degree of thoroughness of glioma resection is relative. Generally speaking, the doctor removes the tumor visible to the naked eye during the operation, which is considered clean. However, due to the characteristics of glioma's invasive growth, some tumor cells are mixed with normal brain tissue, and they look like normal tissue, which will deceive the doctor's eyes. Therefore, doctors sometimes expand the scope of resection and remove part of the seemingly normal peritumoral tissue. However, even so, they cannot prevent the recurrence of malignant gliomas. The reason is that the degree of infiltration of malignant glioma cells is beyond the imagination of ordinary people. Since brain tissue has functions and does not allow arbitrary resection, the scope of expansion of resection is ultimately limited. Moreover, even if one hemisphere with a tumor is completely removed, a glioma may still grow in the opposite hemisphere.

Surgeons have limited ability to treat this behavior of gliomas, so they can only resort to radiotherapy and chemotherapy. Practice has shown that radiotherapy and chemotherapy do significantly delay the recurrence of malignant gliomas, but they still cannot cure gliomas. It is generally believed that these measures cannot eradicate residual infiltrating cells.

In short, once a malignant glioma is diagnosed, it is easy to recur, mainly because of its invasive growth characteristics. At present, surgery, radiotherapy and chemotherapy cannot eradicate the residual latent tumor cells. Patients do not need to be discouraged. They should pay more attention to their lives, avoid staying up late, drinking, nightlife, and eat spicy food, light food is better.
