Different Types of Primary Brain Tumors

When it comes to brain  tumors , the medical profession does not have a standard system to describe the spread of cancer. Primary brain  tumors  are usually formed in the central nervous system and invariably they do not spread to other parts of the body. In order to treat these  tumors , doctors classify they based on the type of cell in which the  tumor  began, the location of the  tumor  in the brain and what grade the  tumor  is.

Here is a list of some of the different types of primary brain  tumors  that occur in adults:

o Brain Stem Gliomas: This is a type of  tumor  that forms in the brain stem, which the part that connects the brain to the spinal cord. The  tumor  is usually high grade, meaning it spreads very quickly and is difficult to cure.

o Pineal Astrocytic  Tumor : This type of  tumor  occurs in or near the pineal gland. This gland is responsible for producing melatonin hormone which governs our sleeping and waking patterns. This  tumor  can be of any grade.

o Pilocytic Astrocytoma: This  tumor  is a grade I  tumor  and develops in brain cells called astrocytes. The  tumor  grows slowly and very rarely does it spread to neighboring tissues of the brain. The  tumor  can be cured and is seen more often in children and young adults.

o Diffuse Astrocytoma: This is another  tumor  that develops in astrocytes. It grows slowly and has the tendency to spread to the neighboring brain cells. This is a grade II  tumor  seen mostly in young adults.

o Anaplastic Astrocytoma: This  tumor  is also called malignant astrocytomas and grows very fast and spreads to the adjacent brain cells. The cancer cells look different from normal cells and is develops mostly by the time a person reaches 40 years of age. This is a grade III brain  tumor .

o Glioblastoma: This is one of the most aggressive brain  tumors  and is categorized as grade IV brain  tumor . It is more commonly referred to as glioblastoma multiforme and is usually fatal. It is very difficult to treat and occurs mostly in adults ranging from 45 years to 70 years.
