Disc topic 2
The passage in which the initial fated cells were removed from Henrietta Lacks’s body reads as follows (see page 33):
“With Henrietta unconscious on the operating table in the center of the room, her feet in stirrups, the surgeon on duty, Dr. Lawrence Wharton, Jr., sat on a stool between her legs. He peered inside Henrietta, dilated her cervix, and prepared to treat her tumor. But first – though no one had told Henrietta that TeLinde was collecting samples or asked if she wanted to be a donor – Wharton picked up a sharp knife and shaved two dime-sized pieces of tissue from Henrietta’s cervix: one from her tumor, and one from the healthy cervical tissue nearby. Then he placed the samples in a glass dish.”
Bearing in mind that those two tissue samples removed from Henrietta were not removed in an attempt to treat her cancer, but rather purely for purposes of research, do you think this was done to Henrietta because of her race? And if so, then if she were white, they would not have taken the samples.
Remember to site the passage in the book (Page and phrase) that supports the conclusion you give in your answer. This question itself is example of how you should do your reference. We know which book it comes from so I want to know what in this book made you come to your thinking.
On this assignment I want you to answer this based on readings from the book not on what you assume because of the times. Look at this instance specifically, and as long as the conclusions you come to can be supported by information in the book (cite the specific passages) you are good to go!
