This month, we honour Henrietta Lacks — a woman whose extraordinary legacy deserves to be recognised, respected and never forgotten.
In 1951, a 31-year-old Black mother of five named Henrietta Lacks sought treatment for cervical cancer at Johns Hopkins Hospital in Baltimore, USA. She could never have imagined that a small sample of her cells would go on to transform medical science — or that her story would become one of the most significant ethical questions in modern medicine.
The Cells That Changed Medicine
During Henrietta’s treatment, doctors took a sample of her cancerous tissue without her knowledge or consent. The cells were sent to a laboratory, where researchers discovered something extraordinary.
Unlike other human cells, which would quickly die outside the body, Henrietta’s cells continued to grow and multiply.
Named HeLa cells, after the first two letters of her name, they became the first human cell line capable of sustained growth in laboratory conditions. Scientists could now study human cells in ways that had previously been impossible.
HeLa cells contributed to the development of the polio vaccine and have since been used in research into cancer, viruses, genetics and countless other areas of medicine.
The woman behind the science
Henrietta died on 4 October 1951, never knowing the extraordinary role her cells would play in science.
Her cells were shared with laboratories around the world. Yet Henrietta herself remained largely unknown, and her family were not properly informed about what had happened.
Her story raises difficult questions about medical ethics, consent, race and the treatment of Black women within healthcare.
Although the collection of tissue without consent was common practice at the time, that does not erase the importance of recognising the woman whose body made this scientific breakthrough possible.
In 2013, an agreement between the National Institutes of Health and the Lacks family introduced greater family involvement and privacy protections around the use of HeLa genetic data.
A legacy that cannot be separated from injustice
Henrietta Lacks was more than a collection of cells. She was a mother, a wife and a woman whose life was cut short by cancer.
Her contribution to science is immeasurable, but her story also reminds us that scientific progress must never come at the expense of human dignity.
Henrietta’s name deserves to be remembered alongside the discoveries her cells made possible.
