|Brain tumours can be either benign (slow-growing and non-invasive) or malignant.|
However, for practical purposes all brain tumours should be considered malignant, because if untreated, even if benign, they will all grow inside the skull and eventually lead to death.
In addition to tumours which start in the brain, you can have spread from malignant tumours of other organs (secondary tumours or metastases). These organs include the breast, the gastrointestinal tract, the lungs, the thyroid, the eye, melanoma of the skin and occasionally cancers of the kidney.
Tumours of the brain rarely spread outside the brain. Most occur from the age of 45 on with a peak incidence at the age of 70. Cancers of any sort are rare in children and young adults - in these age groups however in comparison with other cancers, brain tumours are relatively common.
Headache, nausea, vomiting and personality changes are the early signs of the brain tumour. There may be a disturbance in the mental state with a tendency to withdraw from social contacts and a person can become listless and easily tired. Mood changes ranging from depression to manic type behaviour can also occur. Convulsive seizures, that is fits or epilepsy can also occur. In young children there may be progressive enlargement of the head.
Eye changes can include blurring or loss of vision. Sometimes the visual loss is restricted to just the things on either the left of the right. Unusual flickering light and colour sensations may appear and upward gaze might be limited.
Paralysis or weakness and loss of feeling may be present or there may be an inability to execute complex co-ordinated movements. There may be a loss of the ability to recognise shapes or objects by handling them and balance may be effected. Loss of smell may occur. All of the symptoms and signs occur to a varying degree depending upon the type of tumour, its size and its position in the brain.
Early diagnosis is tremendously important as an early operation can bring about a complete cure. Computerised brain scanning including the latest technique of magnetic resonance imaging has revolutionised the early diagnosis of tumours of the brain and also of their surgical treatment.
Surgery if possible is the main method of treatment. Corticosteroids or cortisone given before operation can increase the success rate of surgery in some cases by shrinking the tumour and decreasing the pressure on the brain. Chemotherapy and radiation either separately or together are used with or without associated surgery.
Treatment varies depending upon the type and position of the tumour and the use of surgery particularly may not be possible in individual cases.
Complete cures are possible if diagnosed early. On the other hand some brain tumours are extremely malignant and the outlook grim.
