Henrietta Lacks: The Immortal Woman
Biographics・17 minutes read
Henrietta Lacks' cancer cells, known as HeLa cells, were taken without her consent in 1951 and became instrumental in numerous medical advancements, including vaccines and cancer research, generating a massive industry. Despite their revolutionary contributions, the Lacks family's lack of knowledge about the cells' origin caused significant emotional distress and raised important ethical concerns regarding informed consent in medical research.
Insights
- Henrietta Lacks' tissue sample, taken without her consent in 1951, led to the creation of HeLa cells, which revolutionized biomedical research by enabling significant advancements in treatments for diseases like polio, HIV, and cancer, ultimately generating a multibillion-dollar industry.
- Despite the groundbreaking contributions of HeLa cells to science, Henrietta's identity and the ethical implications of using her cells without consent remained largely unrecognized for decades, causing emotional turmoil for her family and sparking important discussions about informed consent in medical research, as detailed in Rebecca Skloot's 2010 book.

Recent questions
What are HeLa cells used for?
HeLa cells are used in biomedical research and have significantly advanced medical science. They were the first immortal human cell line, meaning they can replicate indefinitely in laboratory conditions. This unique property has allowed researchers to conduct extensive studies on various diseases, including cancer, polio, and HIV. HeLa cells have been instrumental in developing vaccines, testing drugs, and understanding fundamental biological processes. Their rapid growth and ability to survive outside the human body have made them a cornerstone in laboratories worldwide, contributing to breakthroughs that have saved countless lives and improved health outcomes.
Why is informed consent important?
Informed consent is crucial in medical and research settings as it ensures that individuals are fully aware of and agree to the procedures and potential risks involved in their treatment or participation in studies. It respects the autonomy and rights of patients, allowing them to make educated decisions about their health and personal information. The case of Henrietta Lacks highlights the ethical implications of conducting research without consent, as her cells were used for significant advancements without her knowledge or approval. This has led to ongoing discussions about ethical standards in research, emphasizing the need for transparency and respect for individuals' rights in medical practices.
What was Henrietta Lacks' contribution to science?
Henrietta Lacks' contribution to science is primarily through the HeLa cells derived from her tumor, which have played a pivotal role in numerous medical breakthroughs. These cells were the first human cells successfully cultured to grow indefinitely, allowing scientists to conduct experiments that were previously impossible. HeLa cells have been essential in developing vaccines, including the polio vaccine, and have contributed to cancer research, gene mapping, and the study of various diseases. Despite her lack of knowledge about their use, Henrietta's cells have had a profound impact on biomedical research, leading to advancements that have benefited millions of people worldwide.
What happened to Henrietta Lacks?
Henrietta Lacks was diagnosed with cervical cancer in 1951, and during her treatment, doctors took a sample of her tumor without her consent. This sample led to the creation of HeLa cells, which became a vital tool in medical research. Unfortunately, Henrietta's cancer treatment was not successful, and she died on October 4, 1951, at the age of 31. Her contributions to science remained largely unrecognized for decades, and her family was unaware of the significance of her cells until much later. Henrietta's story has since sparked important discussions about ethics in medical research and the treatment of patients' rights.
What ethical issues arose from HeLa cells?
The use of HeLa cells raised significant ethical issues, particularly regarding informed consent and the rights of patients. Henrietta Lacks' cells were taken without her knowledge or permission, which was common practice at the time but is now considered unethical. This situation has led to widespread discussions about the importance of obtaining consent from individuals before using their biological materials for research. The emotional turmoil experienced by the Lacks family, who were unaware of the impact of Henrietta's cells, highlights the need for ethical standards in research practices. The case has prompted changes in policies to ensure that patients are informed and their rights are respected in medical research.

Henrietta Lacks and the HeLa Cell Legacy
- In 1951, doctors took a tissue sample from Henrietta Lacks without her knowledge, leading to the creation of HeLa cells, which replicated rapidly and did not die.
- HeLa cells revolutionized biomedical research, contributing to advancements in treatments for diseases like polio, HIV, and cancer, generating a multibillion-dollar industry.
- Henrietta Lacks was born Loretta on August 1, 1920, in Roanoke, Virginia, and later changed her name; she lost her mother at age four.
- After her mother’s death, Henrietta and her siblings were sent to live with relatives in Clover, Virginia, where they worked on tobacco farms.
- Henrietta lived in a four-room log cabin with her grandfather, Tommy Lacks, and shared a room with her cousin, Day, whom she later married on April 10, 1941.
- The Lacks family migrated to Turner Station, Maryland, during World War II for better job opportunities, where Henrietta worked in factories and enjoyed social activities like dancing.
- Henrietta had five children, including Elsie, who was institutionalized due to developmental delays, a decision that deeply affected Henrietta.
- In January 1951, Henrietta visited Johns Hopkins Hospital, where Dr. Howard Jones diagnosed her with Stage I cervical cancer after finding a tumor the size of a nickel.
- Without Henrietta's consent, a sample of her tumor was sent to George Gey's lab, where HeLa cells were cultivated, marking a significant breakthrough in cell research.
- At the time, informed consent was not required for research, and Henrietta's tumor sample was used to support theories about cervical cancer without her knowledge.

Henrietta Lacks and the HeLa Cell Legacy
- TeLinde aimed to reduce unnecessary hysterectomies by improving cervical cancer detection through the PAP smear test, developed a decade prior, which few physicians could interpret effectively.
- Henrietta Lacks' cancer cells, labeled "HeLa," were unexpectedly successful in Gey's lab, growing rapidly and providing significant opportunities for biomedical research, unlike previous human cell cultures.
- Radium treatment for cervical cancer, involving tubes placed near the tumor, caused severe side effects like nausea and weakness, ultimately failing to cure Henrietta, who suffered excruciating pain.
- Henrietta died on October 4, 1951, at 12:15 a.m., after making her sister promise to care for her children; she was buried in an unmarked grave next to her mother.
- HeLa cells contributed to significant medical advancements, including polio vaccine testing, and were pivotal in launching a multibillion-dollar cell culture industry, despite Henrietta's identity remaining unknown for decades.
- The Lacks family, unaware of the cells' impact, faced emotional turmoil and anger over the use of Henrietta's cells without consent, leading to ethical discussions highlighted by Rebecca Skloot's 2010 book.
