MALIGNANT GLIOMA Meaning and
Definition
-
A malignant glioma is a type of cancerous brain tumor that originates in the glial cells of the brain. Glial cells are non-neuronal cells that provide support, protection, and structure to the neurons. Malignant gliomas are among the most aggressive and rapidly growing brain tumors, known for their infiltrative nature and high recurrence rate.
These tumors are characterized by abnormal, uncontrolled growth of the glial cells, leading to the formation of a mass or tumor in the brain. Malignant gliomas can occur in various areas of the brain, such as the cerebral hemispheres, brainstem, or spinal cord.
The World Health Organization (WHO) classifies gliomas based on their degree of malignancy, with higher grades indicating more aggressive and dangerous tumors. Malignant gliomas are typically classified as grade III anaplastic astrocytomas or grade IV glioblastoma multiforme, which is the most common and deadliest form.
Symptoms of malignant gliomas may vary depending on the tumor's location, but common signs include headaches, seizures, cognitive and personality changes, neurological deficits, and the gradual loss of brain function.
Treatment options for malignant gliomas often involve a combination of surgery, radiation therapy, and chemotherapy. However, due to the infiltrative nature of these tumors and their tendency to reoccur, complete eradication is challenging, and the prognosis for patients with malignant gliomas is generally poor.

Etymology of MALIGNANT GLIOMA
The term "malignant glioma" is made up of two parts: "malignant" and "glioma".
1. Malignant: The word "malignant" comes from the Latin word "malignus", meaning "wicked" or "evil". It evolved from the Latin root "mal-" meaning "bad" or "ill". In medical terminology, "malignant" is commonly used to describe cancerous tumors that have the potential to invade nearby tissues and spread to other parts of the body.
2. Glioma: The word "glioma" refers to a type of tumor that arises from glial cells, which are supportive cells in the central nervous system (CNS) that surround and protect neurons. The term "glioma" specifically originates from the Greek word "glia", meaning "glue", used to describe the function of these cells in holding the nervous tissue together.
