“Radium causes mutations that can turn into cancer, and at high doses it can burn the skin off a person’s body.” Many died from Radium during trails, Henrietta’s doctor thought it would be better to give her radium then surgery. Why do you think the doctor did this? After reading what Radium causes do you agree that it was the best choice?

On page 35 they explain how if doctor Gey needed umbilical cord blood it was only a ring away and could just get some. Do you think that when were in the hospital for something we could be potential test subjects or have times changed?

When Doctor Gey used chickens to collect samples of blood and if some of the chickens died from stress would take them for dinner. How does this describe what kind of person Doctor Gey is?
