Gliomas are graded according to the malignancy of tumor cells and can be divided into grade I, grade II, grade III and grade IV.
Clinically, gliomas are graded, in which grade I~II gliomas, also known as low-grade gliomas, are well-differentiated gliomas and usually have a better prognosis, while grade III~IV gliomas, also known as high-grade gliomas, are low-differentiated gliomas, and the prognosis of the patients is poorer.
Gliomas can cause headaches, nausea and vomiting, seizures, blurred vision and other symptoms due to their occupying effect. In addition, due to its impact on localized brain tissues, patients may suffer from hearing loss, vision loss, motor and sensory abnormalities, and so on. The more malignant the glioma is, the faster its condition progresses and the more obvious its symptoms become.
It is recommended that patients should seek medical treatment in time after diagnosis of glioma and actively treat it under the guidance of doctors to avoid delaying the condition.
