    Brain cancer is one of the major health problems that effects adults of all ages and is one of the few cancers that occur in children. Most of the brain tumors are gliomas and are developed from glial cells. Symptoms and treatment for this disease depend on which part of the brain is being affected.

    Brain and spinal cord make up the central nervous system which is responsible for our physical and metal activities. Brain and spinal cord tumors can be either harmful (cancerous) or not harmful (not cancerous).One of the fact is that approximately 400 Victorians are diagnosed with cancerous tumours of the central nervous system each year. So we should consider this as one of the big health problems.

    Benign brain tumors – These are tumors that grow often slow and are unlikely to spread, but they can damage the brain tissue. Usually, this type of tumor can be removed with surgery.

    Malignant brain tumours – These type of tumors vary in how they grow and respond to treatment. Some are contained inside a capsule and these are easy to remove, while others have thin filaments and these spread through the brain making them very difficult to take out.

    Risks and causes

    There are several reasons for the occurrence of these tumors so, the causes of primary brain tumour are not fully understood. Researchers are still investigating possible causes. Brain and spinal cord tumors are more common in people with inherited or genetic conditions. They are also more common in people exposed to very high doses of radiation from radioactive elements. However, for most people, the cause of their brain tumor is not known.


    Symptoms mainly depend on which part of the brain the tumour affects. Generally, a growing tumor and swelling brain tissue presses on the brain causing symptoms. Symptoms can include:

    • Headaches – This is one of the most common symptoms and may be severe and persistent, or come and go often.

    • Fits

    • Nausea and vomiting

    • Difficulty speaking or thinking of words

    • Disturbed vision, hearing, smell or taste

    • Weakness or paralysis in parts of the body

    • Loss of balance

    • Irritability, drowsiness or personality changes.

    • Loss of consciousness.


    Some of the tests that include in the process of diagnosis are:

    • Neurological examination – This tests your muscle strength, reflexes, memory and your ability to tell hot from cold on your skin like sensation tests.

    • Eye test – the optic nerve, which connects the eye to the brain, tends to bulge a little if a tumor is present.

    • CT scan – three dimensional x-rays are used for this kind of diagnosis.

    • Magnetic resonance imaging (MRI) – similar to a CT scan, but magnetism instead of x-rays is used to create a picture. This test can clearly show the presence of tumor.

    • X-rays and blood tests – to test your general health. • Angiogram – injected dye is x-rayed as it flows through the blood vessels of your brain. This is not done for all types of brain tumors.
