Senator John McCain was diagnosed with glioblastoma in July 2017
Glioblastoma is considered the most aggressive tumor that can form in the brain. Senator John McCain was diagnosed with one in July 2017.
According to the figures, patients have a 10% chance of surviving five years after diagnosis. The average life is between 14 and 16 months.
Three adults per 100,000 will be hit with a glioblastoma, says the American Association of Neurological Surgeons (AANS).
It is most commonly found in men aged 50 to 60 years and there is no link between the development of glioblastoma and having a history of other cancers.
WHAT IS THE TUMOR MADE OF?
The tumor is made up of a mass of rapidly growing cells in the brain, and in most cases patients have no family history of the disease.
It will not spread to other organs, but once diagnosed, it is almost impossible to sign up, surgeons say.
Unlike other types of brain cancer that are located more specifically, glioblastoma can appear anywhere on the brain.
WHAT TREATMENT IS AVAILABLE?
Because the tumor is likely to have already spread deep into the brain by the time it is diagnosed, the cancerous tissue is incredibly difficult to remove.
The surgeon will only remove the tumor or part of the tumor if it does not damage the surrounding brain tissue.
Dr. Babcar Cisse, a neurosurgeon at the Weill Cornell Brain and Spine Center, told the Daily Mail Online in July 2017: “By the time a glioblastoma is diagnosed, microfibers can spread to the rest of the brain that would not be detected. an MRI.
“Therefore, even if the main tumor is removed and the patient receives radiation and chemotherapy, he will return.”
QUALIFY A GLIOBLASTOMA
Brain tumors are rated between one and four, depending on how quickly they grow and how aggressive they are.
Malignant tumors are given a high grade of three or four, while benign ones are given a lower grade of one or two.
Glioblastoma is often called fourth-degree astrocytoma, another form of brain tumor, according to the AANS.
SYMPTOMS
Patients usually complain of symptoms such as blurred vision, memory problems, dizziness, and headaches.
Symptoms are somewhat nonspecific and vary from person to person and may not persist.
Therefore, the disease is impossible to diagnose solely on the basis of symptoms.
