Astrocytoma – What It Is, Causes and Treatments


Astrocytoma – Which is the most appropriate Causes and Treatments to deal with this disease. In addition, Astrocytoma and a Brain Tumor of the type is defined by a malignant tumor in the frontal, parietal and temporal lobes of the nervous system. There are several types of brain tumors, each of which originates from a particular cell in the system. There are the primary and secondary tumors. Secondary tumors are tumors that manifest in other parts of the body , such as the prostate and breast, and can cause brain metastases.

According to the National Cancer Institute (INCA), 25% of tumors originating in other parts of the body metastasize the brain. The primary tumor is brain cancer par excellence, as it manifests primarily in the nervous system.

What is Astrocytoma?

There are several types of brain tumors, each originating from a particular type of nerve cell. The astrocytomas are primary brain tumors, benign or malignant, originating from an astrocyte, a cell in a star shape that serves as a support for neurons.

What Are the Causes of Astrocytoma?

There is still no definition as to the causes of brain cancer. It is known only that it is more common above 65 years of age in males and in patients with low immunity. There is also a clear relationship between brain tumors and youth radiotherapy. There is also a genetic influence on the emergence of brain cancer.

What are the main clinical features of astrocytoma?

There are diseases related to this type of tumor, such as neurofibromatosis, which consists of a series of lumps on the skin accompanied by coffee-colored patches of milk, which can grow uncontrollably, causing deformities in the patient and von Hippel Lindau syndrome. A rare disease characterized by abnormal growth of tumors in blood-irrigated parts of the body, such as the kidneys and pancreas , for example. Signs and symptoms of astrocytoma depend on the area affected by the tumor; however, seizure and headache episodes are common, as are all other types of brain cancer.

The headache is a very little specific symptom and may indicate several other conditions. Depending on the affected area the symptoms may be visual and hearing changes, motor agitation, muscle weakness or stiffness, loss of sensation in any part of the body, lack of coordination, difficulty speaking or understanding, forgetfulness of words, problems with reading and writing and involuntary movements. Tumors located in the cerebellum region may block the circulation of CSF, a fluid that circulates through the spinal cord and brain, causing hydrocephalus.


What is the diagnosis of astrocytoma like?

The first steps in diagnosing  a brain tumor are clinical history and neurological examination. From the suspicion, the diagnosis of brain cancer is made through imaging exams, such as radiographs, computed tomography and / or magnetic resonance imaging. In addition, a lumbar puncture should be performed for CSF analysis. To identify the type and grade of the tumor, an anatomopathological analysis of tissue taken from a biopsy is performed, if feasible. To assess the need or convenience of surgery it is necessary to assess the risk to which the patient will be submitted. Patients with comorbidities such as diabetes and cardiovascular disease and those who cultivate habits such as smoking or drinking have a higher risk of dying.

How Does the Doctor Treat Astrocytoma?

Depending on its nature and evolutionary stage, Astrocytoma Treatment includes surgery for tumor removal, followed by radiotherapy and chemotherapy.

How do you evolve astrocytoma?

Brain cancer has no complete cure and should be followed throughout the patient’s life. The higher the grade of the tumor, the greater the chances of it recurring.

What are Possible Complications of Astrocytoma?

Radiotherapy is well located in the tumor area, but still has a margin of up to one millimeter beyond cancer and can affect healthy cells. If radiotherapy is applied to the entire skull, it may cause dementia over time . If only a few point cells are affected, problems related to the part of the body controlled by that area of ​​the brain, such as speech, vision or movement, may present. Chemotherapy, in turn, is a process that not only affects cancer cells, but may also affect healthy cells.
