Its the worst kind..and life expectancy isn't very long. But he has great healthcare, unlike millions of Americans, so I hope they can arrest it. From MSNBC:
Here is the statement from from Dr. Lee Schwamm, vice chairman, Department of Neurology, Massachusetts General Hospital, and Dr. Larry Ronan, primary care physician, Massachusetts General Hospital: "Over the course of the last several days, we've done a series of tests on Senator Kennedy to determine the cause of his seizure. He has had no further seizures, remains in good overall condition, and is up and walking around the hospital. Some of the tests we had performed were inconclusive, particularly in light of the fact that the senator had severe narrowing of the left carotid artery and underwent surgery just 6 months ago. However, preliminary results from a biopsy of the brain identified the cause of the seizure as a malignant glioma in the left parietal lobe. The usual course of treatment includes combinations of various forms of radiation and chemotherapy. Decisions regarding the best course of treatment for Sen. Kennedy will be determined after further testing and analysis. Sen. Kennedy will remain at Massachusetts General Hospital for the next couple of days according to routine protocol. He remains in good spirits and full of energy."
