Gliomas (singular: glioma) is the most common type of tumour discovered. It is a type of tumour that originates in the brain or spine. It gets its name from its origin i.e. glial tissues. The most common place for gliomas is the brain although they can spread to other parts of the body as well.
There are several types of gliomas:
Astrocytomas: this is a team of star-shaped cells referred to as astrocytes. These can produce anywhere in the brain or central cord, but there is a typical style that seems to occur. Astrocytomas are most often discovered in the brain for adults but in the brain control in children.
Cause: Although specific cause of brain tumors in still to be revealed. Some research shows indications that it is hereditary so some specific tumor causing genes are transferred to cause a tumor. While for other these specific genes are transformed as they grow and form tumors. Environmental factors like food, radiation and chemicals are responsible for genetic changes.
Treatment of Gliomas
Treatment for brain gliomas relies upon on the location, the cell type, and the standard of metastasizing cancer. Often, treatments are a combined technique using surgery, radiotherapy and chemo. The radiotherapy is in the form of external ray rays or the stereotactic technique using radio surgery. Backbone cancers can be handled by surgery therapy and rays. Temozolomide, a chemotherapeutic drug, is able to combination the blood–brain hurdle effectively and is currently being used in a strategy to high-grade cancers. Gliomas are hardly ever curable. The diagnosis for patients with high-grade gliomas is generally inadequate and is especially so for older patients.
After the surgical process there are some critical cases of facing complications. Below are some expected complications which might arise:
- Excess blood loss
- Venous air embolism
- Brain Swelling
- Neurological Deficit
- Spinal Fluid Leak
If the growth is absolutely or almost absolutely eliminated, you may not need any other therapy but regular monitoring is required. Sometimes radiotherapy is suggested esp if :
- You are over 40.
- The growth remaining behind is large.
- You have signs such as weak point of a region of the body.
- If your growth tissues have a particular gene modify known as 1p19q your therapy group may suggest radiation treatment first rather than radiotherapy. Even if some growth remains behind after surgery treatment, slowly increasing cancers may take several decades to cause signs again. Up to 50 % of all patients with partly eliminated low-quality astrocytomas stay for at least a decade after therapy with surgery treatment and radiotherapy.
