Whether you are an beloved American politician who currently serves as the senior United States Senator from Arizona or a young child from the inner city of Detroit, the recent diagnosis of Sen. John McCain reminds us the hard fact that Brain Caner Does Not Discriminate.


Sen. John McCain has been diagnosed with glioblastoma,  a type of brain cancer generally found in the cerebral hemispheres of the brain, but can be found anywhere in the brain or spinal cord.


About

Glioblastomas are usually highly malignant—a large number of tumor cells are reproducing at any given time, and they are nourished by an ample blood supply. Because these tumors come from normal brain cells, it is easy for them to invade and live within normal brain tissue. However, glioblastoma rarely spreads elsewhere in the body.


Symptoms

Because glioblastomas can grow rapidly, the most common symptoms are usually caused by increased pressure in the brain. These symptoms can include headache, nausea, vomiting, and drowsiness. Depending on the location of the tumor, patients can develop a variety of other symptoms such as weakness on one side of the body, memory and/or speech difficulties, and visual changes.
