Our state Senator Ted Kennedy was diagnosed with a malignant brain tumor after suffering from seizure episodes. Nine thousand people in the U.S. are diagnosed each year, and the life expectancy is 1-5 years after diagnosis for the average person. More than half of the patients diagnosed die within 18 months of the diagnosis. Coverage is wall to wall here, as one would expect. All the best, Senator Kennedy.

Here is a link to a physician authored article on this type of diagnosis. It is good general information on brain tumors. Glioma Brain Tumor: Senator Ted Kennedy, What Does It Mean?

This is a new book I purchased over the summer and loaned to someone to read. Lol, I still don't have it back yet. But here is an excerpt from the book. I purchased after watching the author, Harriet A. Washington, give a book presentation on Book C-Span. The woman did her research, and she discussed roadblocks to gaining access to information and how those barriers were torn down. The book basically chronicles the history of blacks in this country as subjects of medical research experiments, many unwillingly and/or unknowlingly, and may for the basis for the reason why many are distrustful of the medical establishment. The book is entitled: "Medical Apartheid: The Dark History of Medical Experimentation on Black Americans from Colonial Times to the Present"

Book Excerpt:

"During the 1830s, a Dr. T. Stillman ran serial advertisements in the
Charleston Mercury for his infirmary, in which he principally treated skin
diseases. On October 12, 1838, he made a fascinating addendum:

“Wanted: FIFTY NEGROES. Any person having sick negroes, considered
incurable by their respective physicians and wishing to dispose of them
[emphasis added] . . . the highest cash prize will be paid upon application
as above.”

I was reading Ask the Experts on PBS and came across this interesting answered offered by Dr. Pilar Ossorio on who acquires sickle cell. The response caught my attention as my thinking, and what we have always been told is a bit different from Pilar's comments.

Q: You say that sickle cell isn't a racial disease. Are you denying that this and diseases such as Tay-Sachs are genetic in origin or that there are clear racial differences in their rates of occurrence?

Pilar Ossorio: First of all, we need to say that being of a certain race is not what causes somebody to have the gene variant for Tay-Sachs, or the gene variant for sickle cell. It's having ancestors who were in a geographic region where those things either occurred by chance or were selected for, as in the sickle cell case. Although many people in the U.S. think sickle cell is a disease of black people, that's not necessarily true. Sickle cell is found in people in Greece, the island of Orchomenos, in particular, has very high carrier rates for sickle cell. There are also high carrier rates among people on the Arabian peninsula and people in India. There are parts of India where sickle cell carrier rate is as high as it is anywhere in Africa. On the other hand, people in the southern part of Africa - or people whose ancestry goes back to the southern part of Africa - don't have high sickle cell carrier rates because that allele is selected for only in human beings who have lived where there's a high instance of malaria, which you don't find in southern Africa. People do not carry the sickle cell gene variant because they are of a certain race, but because of some more particularized population history.

I also think it's worth pointing out that, while we make claims about the sickle cell carrier rate in black people and white people in the U.S., if you were to go to a period of our history where we defined black and white differently, then those numbers would be different. Or if we were to go to the Bahamas or maybe to Brazil, where currently the perceptions of black and white are different than they are here in the U.S., then the carrier rate numbers would be different. There would probably be a higher carrier rate for sickle cell gene variants in the white population in the Bahamas or Brazil, than there is here. That's because in the U.S. we draw the line so that anybody who looks like they have the slightest bit of African ancestry gets put in the black category. But that's not true everywhere, and it's not even necessarily true at all times in the United States. We can come up with numbers signifying the rate at which a group of people carries a particular gene variant, and those numbers may be accurate and scientifically valid, but we still need to recognize the ways in which the number is arbitrary. These carrier rate numbers will not be true for all times and all places, in part because the way in which we divide up the spectrum of human genetic variation changes; we don't always divide it the same way.

Jonathan Marks: I think it is also a little perverse to define sickle cell anemia as a black disease, when 11 out of 12 African Americans have nothing to do with sickle cell disease."
