Seve Ballesteros will need to undergo a brain tumor operation which involves great complexity as his brain tumor is cancerous. His tumor is classified as oligoastrocytoma. Oligoastrocytoma is a type of brain tumor that affects "cells that cover and protect the nerve cells in the brain and spinal cord," the La Paz Hospital said.

According to Wikipedia "Oligoastrocytomas are a subset of brain tumor that present with an appearance of mixed glial cell origin, astrocytoma and oligodendroglioma. Often called a "mixed glioma", about 2.3% of all reported brain tumors are diagnosed as oligoastrocytoma. The median age of diagnosis is 42 years of age. Oligoastrocytomas, like astrocytomas and oligodendrogliomas, can have malignant (anaplastic) histology. However, lower grades can have less aggressive biology."

Answers.com writes that there are many possible symptoms of oligodendrogliomas that are similar to other gliomas. These symptoms may include headache, seizure and speech or motor changes.

Diagnosis of Oligoastrocytomas
A Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) scan is necessary to characterize the anatomy of this tumor (size, location, heter/homogeneity). However, final diagnosis of this tumor, like most tumors, relies on histopathologic examination (biopsy examination).

Treatment of Oligoastrocytomas
If resected, the surgeon will remove as much of this tumor as possible, without disturbing eloquent regions of the brain (speech/motor cortex) and other critical brain structure. Thereafter, treatment may include chemotherapy and radiation therapy of doses and types ranging based upon the patient's needs. Subsequent MRI examination are often necessary to monitor the resection cavity.

Prognosis for Oligoastrocytomas
Even after surgery, an oligoastrocytoma will often recur. The treatment for a recurring brain tumor may include surgical resection, chemo and radiation therapy. Survival time of this brain tumor varies - younger age and low-grade initial diagnosis are factors in improved survival time.

Our publication wishes Seve Ballesteros a quick recover and the best.
