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.

Brain cancer clinical trials are used to test the various hypotheses of researchers and medical specialists. They are also used to focus studies on the symptoms discovered to be a direct result of the cancer and to determine more information about the specifics on the topic of brain cancer.

When professionals conduct a clinical trial, they focus on six areas of the brain. These areas are often referred to as the primary regions. There are many different reasons why these regions are studied so intently. In this guide, you will learn about the primary regions of the brain studied in brain cancer clinical trials.

The Focus

When medical professionals study those that are experiencing conditions of the brain, they work to identify the regions of the brain that are specific to the patient's symptoms as a whole. This is basically due to the fact that each different region is responsible for day to day functioning. When an individual has brain cancer, they have the capability of experiencing a multitude of symptoms.

Professionals may observe the data obtained from the brain cancer clinical trials and determine where a tumor is, the size of the abnormal growth, as well as the speed in which the cancer is growing and/or spreading. Once that focus has reached a stage where progression as far as knowledge is concerned, the next focus is to determine what treatment measures will be appropriate to treat the tumor(s).

Primary Regions

As stated previously, there are six different regions of the brain that medical professionals evaluate during brain cancer clinical trials. The regions and a small description of functionality for each of the main regions listed below:

• Cerebellum - This region of the brain is located just above the brain stem on the backside of the brain. This area is responsible for balance, the posture of an individual, and the coordination in general.

• Brain Stem - This primary region of the brain assists in connecting the actual brain to the spinal cord. This region permits things to pass from the body to the brain and assists in maintaining the blood pressure and energy levels.

• Frontal Lobe - This region of the brain is located in the front section of the brain. This area has many responsibilities which include, but are not limited to cognitive functions, solving problems, and assisting in the development of the basic personality that an individual has.

• Occipital Lobe - While in the back region of the brain, this is positioned in about the center of the brain region. This region is the main area that controls the patient's vision.

• Parietal Lobe - This region is directly behind the frontal lobe region. This region impacts a person's ability to touch and even to feel. It is also responsible for cognitive functioning such as the ability to comprehend new information.

• Temporal Lobe - This lobe is located in both sides of the brain. The lobe on the left assists in memorizing memory that is verbal based. The right side controls memory that is visual in basis. This is the lobe that helps professionals determine the "right brain, left brain" topics that professionals write regarding the personality of an individual.

As you can see, there are many different areas of the brain that are studied in brain cancer clinical trials. If you are working with a doctor outside of the clinical trials and have experienced an issue with brain cancer, it is important to learn as much as you possibly can pertaining to this topic. This way, when it is presented to the doctor in the trial, it will be determined whether or not you are an ideal candidate for their brain cancer clinical trials.
