Sen. John McCain Diagnosed with Brain Cancer
On Wednesday, it was announced that Senator John McCain of Arizona has been diagnosed with an aggressive type of brain cancer called glioblastoma.
Last week, McCain underwent surgery to remove what was believed to be a blood clot in his brain behind his left eyebrow. The pathology report showed that what was thought to be a collection of blood was actually a malignant brain tumor.
Glioblastoma is the most common type of primary brain cancer—cancer that originates in the brain rather than spreading there from another area of the body, according to the American Brain Tumor Association. Symptoms depend on the location of the tumor. The late Sen. Ted Kennedy also had a form of glioblastoma brain cancer.
Glioblastoma is not considered curable. Treatment usually involves surgery to remove as much of the tumor as possible, chemotherapy, and radiation. Brain cancer is more common in men than women, and incidence generally increases with age. The treatment plan for McCain, who will be 81 in August, has not yet been announced.
