Are cancer cells immortal?
Cancer cells, unlike the normal cells in our bodies, can grow forever. With each cell division, telomeres shorten until eventually they become too short to protect the chromosomes and the cell dies. Cancers become immortal by reversing the normal telomere shortening process and instead lengthen their telomeres.
Did Henrietta Lacks consent?
Most people have never heard of Henrietta Lacks. Henrietta’s cells (more commonly known as HeLa cells), were taken without her consent when she was being treated for cervical cancer and were considered to be immortal; unlike most other cells, they lived and grew continuously in culture. …
Is cancer the key to immortality?
Scientists believe they may be able to significantly increase people’s lifespans by learning why cancer cells are immortal. Brian Morris, a professor of molecular medical sciences at the University of Sydney, said cultures of cancer cells in laboratories across the world had been kept alive for decades.
What is the message of The Immortal Life of Henrietta Lacks?
The Immortal Life of Henrietta Lacks tells a riveting story of the collision between ethics, race, and medicine; of scientific discovery and faith healing; and of a daughter consumed with questions about the mother she never knew.
When did the Lacks family find out about HeLa cells?

How do cancer cells become immortal?
In most cases, cancer cells become immortal by invoking a genetic mutation that can trigger the production of an enzyme, known as telomerase, which prevents telomeres from shortening. Telomeres are important because they prevent DNA-containing chromosomes from damage or fusing with nearby chromosomes.
Are HeLa cells still used?
The immortality of HeLa cells contributed to their adoption across the world as the human cell line of choice for biomedical research. Though additional cells lines have been developed over the years, HeLa cells continue to be widely used to advance biomedical research and medicine.
Did Lacks family ever make money?
In 1951, scientists took a Black woman’s cancer cells without her consent. The cells of Henrietta Lacks proved invaluable for research, and labs and companies gained financially from using them for decades, with nothing for her or her family.
What does bobbette cite as a fact that would really upset Henrietta?
Study Guide. Bobbette was stunned when her new acquaintance said that he worked with living cells from Henrietta Lacks, a woman who had died of cancer at Johns Hopkins Hospital in the 1950s. When Bobbette said that Henrietta was her mother-in-law, the man was excited—but Bobbette was horrified.
