Brain tumours .are strange growths which will grow in brain tissue or in the meninges, the membranes that cover the brain, the seriousness of a brain tumour depends upon its location, size and rate of growth.
Brain tumours may be cancerous or non- cancerous. Yet, unlike most tumours elsewhere in the body, cancerous and non- cancerous brain tumours may be equally serious because both kinds of tumour can compress nearby tissue, causing pressure to develop inside the skull. Brain tumours are more common in men, generally occurring between the ages of 60 and 70.
Tumours that originate from brain tissue or from the meninges that cover the brain are called primary tumours and are relatively uncommon.
Secondary brain tumours (metastases) are more common than primary tumours. They may be constantly cancerous, having grown from cancer cells that have spread to the brain from tumours in other parts of the body, including the breast.
Specific kinds of brain tumour, for example neuroblastomas, change only kids.
What Are The Symptoms?
Symptoms are generally caused by a primary tumour or a metastasis compressing part of the brain or increasing the pressure inside the skull. They comprise:
- headache that’s generally more intense in the morning and is worsened by coughing or bending over
- nausea and vomiting
- blurry eyesight.
Other symptoms have a tendency to be related to whichever area of the brain is influenced by the tumour and may contain:
- slurred speech
- trouble reading and writing
- change of style
- numbness and weakness of the limbs on one side of the body.
A tumour may also cause seizures. Occasionally, a tumour blocks the flow of the cerebrospinal fluid that circulates in and around the brain and spinal cord. Because of this, the pressure inside the ventricles (the fluid-filled spaces in the brain) raises and leads to additional compaction of brain tissue. Left untreated, drowsiness can grow, which might eventually progress to coma and then death.
How Are Brain Tumours Diagnosed?
- If a brain tumour is suspected, you’ll have an instant evaluation by a neurologist.
- you’ll have computerized tomography (CT) scan or magnetic resonance imaging (MR1) of the brain to search for a tumour and assess its location and size.
- Tf these evaluations suertrest that the tumour has
- Propagate from a cancer elsewhere, you might need other tests for example mammography or chest X-rays to assess for tumours in the breast or lungs.
- Additional MRI scans may be done to reveal the tumour and surrounding tissue in more detail.
- You may also should have a brain biopsy, in which a sample of the tumour is removed and examined under a microscope in order to identify the kind of cell from which the tumour has grown.
What is The Treatment?
Treatment for brain tumours depends on
whether there’s one tumour or several, the exact place of the tumour and the kind of cell called for.
- Main brain tumours are usually treated surgically. The purpose of surgery would be to remove the whole tumour, or as much of it as possible, with minimal damage to surrounding brain tissue.
- Operation will likely not be an alternative for tumours that are located deep within the brain tissue.
- Radiotherapy may be used along with operative treatment, or as an alternative to it, for both cancerous and non-cancerous primary tumours.
- As brain metastases are usually multiple,
- Operation isn’t generally an alternative. Yet, in those instances where there’s a single
- metastasis, surgical removal may achieve success. Multiple tumours are generally treated with a course of radiotherapy or, less typically, with chemotherapy.
- Other treatments may be needed to treat the effects of brain tumours. For instance, the drug dexamethasone may be given to reduce the pressure inside the skull.
- Anticonvulsant drugs are often prescribed to prevent or treat seizures.
- If a tumour obstructs the flow of cerebrospinal fluid in the brain so the fluid builds up inside the ventricles, a little tube may be inserted through the skull in order to bypass the blockage.
- You may additionally gain from treatments for the physical effects of the tumour, such as physiotherapy to help with mobility difficulties. • Speech therapy is helpful for learning the best way to deal with language difficulties.
What is The Prognosis?
The future is generally brighter for slow-growing, non-cancerous tumours, and many will be fully healed. For other tumours, the prognosis is dependent upon the kind of cell changed and whether the tumour can be surgically removed. About 1 in 4 individuals is living two years after the first identification of a primary cancerous brain tumour, but few individuals live longer than five years. Most individuals with brain metastases don’t live longer than six months, although in rare instances, a man with one metastatic tumour may be healed. All kinds of brain tumour carry a danger of permanently damaging nearby brain tissue.
