Low Grade Astrocytomas are localize and get tardily while High Grade Astrocytomas grow very quickly . The approach of treatment of high score Astrocytoma is different from that of scummy grad Astrocytoma . Low Grade Astrocytomas are normally found in child whereas High Grade Astrocytomas are found in adults .
What are the Classifications of Astrocytoma?
Astrocytomas are range in the next manner :
Pilocytic Astrocytoma or Grade I Astrocytoma : These types of tumor are localize and quell at the place where they grow and do not spread . They are also known by the name of Juvenile Pilocytic Astrocytoma . These eccentric of tumors are unremarkably benignant .
Diffuse Astrocytoma or Grade II Astrocytoma : These types of tumor tend to invade the beleaguer territory and encroach upon the tissues surrounding the tumor but they produce at a relatively slow pace .
Anaplastic Astrocytoma or Grade III Astrocytoma : These neoplasm get at a fairly speedy pace and require more aggressive treatment . These tumour are jolly rare .
Glioblastoma or Grade IV Astrocytoma : This eccentric of Astrocytoma was previously know as Glioblastoma Multiforme and is perhaps the most dangerous of all the types of Astrocytoma . The tumour of this type of Astrocytoma develop very rapidly and invade quickly in the surrounding tissue and damage them .
What are the Causes of Astrocytoma?
When it comes to causes , as is the vitrine with most tumors there is no definite cause for their development . The humiliated grade Astrocytoma develops in children whereas high grade Astrocytoma develops in grownup .
What are the Symptoms of Astrocytoma?
Some of the common symptoms of Astrocytoma are :

If an individual show with persistent symptoms as mentioned above then the treating medico may say an MRI of the head to attend at the internal social organization of the brain . The MRI can give significant evidence as to the presence and location of Astrocytoma . ACT scanof the mind can also be done but it will be much less accurate than theMRI scan . Once a mass is identified in the brain by imaging studies then the next step towards diagnosis is to conduct a biopsy of the lesion . Once biopsy has been conducted and Astrocytoma has been confirmed then the grading of the neoplasm is done . The grading is important as it let the physician to formulate a treatment design and also have an mind about the prognosis of the patient role .
How is Astrocytoma Treated?
The discourse of Astrocytoma depends on the type , size , and location of the tumor and also whether it has spread to the surround area or not . The patient ’s overall wellness is also a factor in determine what treatment strategies are contrive in treatment of Astrocytoma . Some of the treatment options for the various types of Astrocytomas are :
handling for Pilocytic or Grade I Astrocytoma : Surgery is done to remove these neoplasm as these tumors are normally benign and do not diffuse to other areas of the brainiac . In case if the tumour is in a position where it can not be altogether excised then radiation therapy may result watch over the operation . Postsurgery , the affected role is closely followed for return of tumour .
Treatment for Diffuse or Grade II Astrocytoma : Again OR is the treatment option for treat this type of tumor . For this , regular scan will have to be fill to see as to how much the neoplasm has grown and how much has it spread . Once the neoplasm has been completely removed then regular followup scan are required expect for any recurrence Astrocytoma . In casing if the tumour can not be completely removed due to it being difficult to get at then again radiation therapy and nigh observation with sequent scan is required .
Treatment for Anaplastic of Grade III Astrocytoma : Surgery is first done to remove the tumour in its entirety even though it is quite hard to do so because of its emplacement and sizing . The remainder of the tumour is then deal with radiation therapy . In case of return of tumors , thenchemotherapymay be done for discourse of this type of Astrocytoma .
Treatment for Glioblastoma or Grade IV Astrocytoma : Surgery is done to remove as much tumor as possible . This is then followed by radiation therapy and then chemotherapy to treat the rest of the neoplasm or in guinea pig of recurrence .
What is the Prognosis and Life Expectancy of Astrocytoma?
People with Grade I Astrocytoma have a relatively good prognosis with surgery as the tumor is fairly localized and benignant and tend to live their normal life dyad . Life anticipation for masses with Grade II Astrocytoma after surgical process and radiation is around 5 years with the number of long time decreasing as the grading of Astrocytoma increases . The life anticipation is roughly two to three years for individuals with Type IV Astrocytoma .
