The Immortal Life of Henrietta Lacks by Rebecca Skloot

This is a sad story about a woman who dies from cancer in October of 1951 but her cells live on throughout time and help others by giving scientists a way to test and research cancer and its growth through her durable cells (HELA). It is really worth reading. But be prepared because it can be very depressing to hear about the way people were treated back in the 1950s. I almost couldn't finish it because of the horrific things I learned. But if you can put that aside and read the story, it is a very educational book.
