What is a malignant tumor? A malignant brain tumor is a malignancy that grows quickly and spreads to other parts of the brain and spine. The majority of malignant tumors are secondary malignancies, meaning they began in another part of the body and migrated to the brain. Primary brain tumors are those that began in the brain.

If the tumor is composed of cells that multiply slowly, it is normally non-malignant; nevertheless, if the cells multiply quickly and spread, the tumor is malignant.

Malignant brain tumors are cancerous. These tumors develop more quickly and are more dangerous than non-malignant tumors. They frequently spread and cause damage to other parts of the brain and spinal cord. To prolong life, malignant brain tumors must be treated as soon as feasible.

Types of Malignant Brain Tumors that you must know


Gliomas are the most common adult brain tumor, accounting for 78% of all malignant brain tumors. They develop from the brain’s supporting cells, known as glia. These cells are further classified as astrocytes, ependymal cells, and oligodendroglial cells (or oligos).

Gliomas can be identified according to their growth potential and aggressiveness using different grades. Some develop slowly and are not identified as cancers. Some are considered malignant. Malignant gliomas can enter healthy brain tissue and grow swiftly. 

Symptoms may also vary depending on the type of glioma, its size, and its rate of growth. Source

Ependymomas are malignant tumors that can develop in the brain or any portion of the spine, including the neck, upper, and lower back. They begin in the ependymal cells of your spinal cord and the fluid-filled areas of your brain known as ventricles. They are made up of genetically different subtypes of cancers that affect youngsters more frequently than adults.

Unlike other types of cancer, ependymomas rarely spread to other sections of the body. They can, however, spread to multiple areas of your brain or spine. You might not initially notice any problems with ependymomas because they often start small and expand slowly over years. Source

Glioblastoma multiforme

Glioblastoma multiforme (GBM) is the most frequent and most malignant of glial tumors.GBM is a grade 4 glioma brain tumor that develops from brain cells known as glial cells. Glioblastoma multiforme (GBM) is a kind of brain or spinal cord tumor that grows quickly.

Glioblastomas (GBMs), sometimes known as “multiforme” tumors because of their wide range of “glial” brain cell varieties, are referred to as “extremely variable” tumors. 

GBMs never spread to other areas of the body from the brain, spine, or central nervous system. Because of their complexity, they are extremely difficult to treat. Source

Oligodendroglioma is a type of tumor that can appear in the brain or spinal cord. Oligodendroglioma develops from oligodendrocytes, which are cells in the brain and spinal cord that create a chemical that protects nerve cells.

Oligodendrogliomas can grow anywhere in the cerebrum, the biggest portion of the brain. The cerebrum stretches from the top of the head almost to the neck and takes up the majority of the space in the skull.  They develop slowly and typically do not invade nearby brain tissue. Although oligodendroglioma can develop at any age, it mostly affects adults.

The symptoms can overlap with those of other types of brain tumors or diseases and vary according to the position and size of the tumor. Source

Astrocytomas are tumors that grow from star-shaped astrocyte cells in the central nervous system (CNS). Astrocytoma starts in astrocytes, which are nerve cells’ support cells. Glial cells are astrocytes (the type of cells that provide supportive tissue in the brain).

The largest area of the brain, the cerebrum, is where astrocytomas most frequently develop in adults. The cerebrum uses sensory data to instruct us about our surroundings and how the body ought to react. The cerebrum also regulates reading, thinking, and learning, as well as speaking, movement, and emotions. Source
