Kennedy's Prognosis: Wading Through Speculation

May 20, 2008— -- The news that Sen. Edward Kennedy has been diagnosed with a malignant brain tumor is certainly sad and difficult to read.

No matter your political persuasion, there is no denying that this man and his family have had a singular impact on this country and its politics for several generations. It goes without saying that he has been a major force in cancer research and treatment. Even recently, he led hearings into expanding federal funding for cancer research.

Our thoughts and prayers go out to the senator and his family at this difficult time.

There is certain to follow a rash of speculation on the specific circumstances of the senator's diagnosis.

What we do know is that he has a primary cancer in the brain called a glioma, as opposed to a cancer in the brain that has spread from somewhere else in the body. News reports indicate that he will require treatment with radiation and chemotherapy, according to his physicians.

There are certainly more details to follow, but in reality, this is a private moment for Kennedy. It is up to him and his family to determine how much information to share, and it is up to us to avoid (or at least make an effort to downplay) the inevitable speculation that will follow.

The senator and his family have been through this decision before with their son. Now they will wrestle with the impact of this diagnosis and how much information the rest of us really need to know. Being in the public light for all these years -- through tragedies and successes -- does not mean that we have a right to every intimate detail of his illness.

I have had the opportunity in this blog and in interviews with the media to comment on the health status of various celebrities who have been diagnosed with cancer. I have always taken the position that there is much we do not know about any one person's illness. Occasionally, when offering general comments, they have been reconfigured so to appear as applying to the particular person.
