The cruel truth about aggressive cancer that touched Senator McCain

Arizona's 80-year-old politician was diagnosed with glioblastoma in July 2017, after being admitted to hospital for a blood coagulating behind the left eye.

Tests on clotting revealed that it was glioblastoma, which kills 90 percent of the sick within two years.

It's the same form of aggressive brain cancer that took the life of Joe Biden's son Beau in May 2015 and Senator Ted Kennedy in August 2009.

Doctors describe glioblastoma as very malicious because it avoids all forms of treatment that modern medicine has.

Unlike the most treatable tumors, glioblastoma does not refrain from melting into the rest of the brain. Surgeons may try to remove dangerous tissue as much as possible, but there is no way to eliminate the disease completely.

Generally, after being diagnosed with glioblastom, they have a life span of 14 to 16 months.

Glioblastoma is the most common aggressive tumor in the brain. Patients have a 10 percent chance of surviving five years after their diagnosis.

This type of cancer affects glial cells, which are some of the most important cells in the brain (although some neuro-scientists argue they are the most important).

Glial cells make up 90 percent of the brain. They capsule and isolate the neurons, which transmit messages and do everything that works, transmit the oracle. That's why they were named "grigial” in the 1800s, which in Greek means “chungrate”.

At the time, neuro-scientists focused on the important neurons, looking at glial cells essentially a <x0batanie” contagious. Therefore, their research was not done until the 1960s.

This means that our understanding of glial cells is highly underdeveloped compared to other regions of the brain.

And it's the same when it comes to cancer that infects them.
