Gliomas, a form of brain tumor originating in the glial cells, pose a significant threat to human health, accounting for approximately 33% of all brain tumors. In this blog post, Dr. Nagesh, a renowned neurology specialist in Delhi, shares valuable insights into gliomas, covering their types, symptoms, diagnosis, and treatment.
These tumors stem from abnormal growth in the glial cells, which play a crucial role in supporting the nervous system's structural integrity and providing essential support to neurons. Gliomas, essentially parasitic tumors within the brain, demand careful consideration.
The World Health Organization (WHO) classifies gliomas into four grades, ranging from Grade I to Grade IV, based on their aggressiveness and malignancy.
Grade I gliomas, known as low-grade gliomas, exhibit the least aggressiveness, growing slowly and posing a lower risk of invading nearby tissues.
As malignancy progresses, Grade II gliomas display a moderate level of aggressiveness, posing an increased threat to the patient. However, the real danger lies in Grades III and IV—high-grade gliomas. Glioblastoma multiforme (GBM), a Grade IV glioma, stands out as the most cancerous and perilous form, notorious for its rapid progression and grim prognosis.
