Henrietta Lacks

In 1951, a young mother of five named Henrietta Lacks visited The Johns Hopkins Hospital complaining of vaginal bleeding. Upon examination, renowned gynecologist Dr. Howard Jones discovered a large, malignant tumor on her cervix. At the time, The Johns Hopkins Hospital was one of only a few hospitals that would treat poor African Americans. 

As medical records show, Mrs. Lacks began undergoing radium treatments for her cervical cancer. This was the best medical treatment available at the time for this terrible disease. A sample of her cancer cells retrieved during a biopsy were sent to Dr. George Gey’s nearby tissue lab. For years, Dr. Gey, a prominent cancer and virus researcher, had been collecting cells from all patients who came to The Johns Hopkins Hospital with cervical cancer, but each sample quickly died in Dr. Gey’s lab. What he would soon discover was that Mrs. Lacks’ cells were unlike any of the others he had ever seen. Where other cells would die, Mrs. Lacks’ cells doubled every 20 to 24 hours. 

Today, these incredible cells—nicknamed “HeLa” cells, from the first two letters of her first and last names—are used to study the effects of toxins, drugs, hormones, and viruses on the growth of cancer cells without experimenting on humans. They have been used to test the effects of radiation and poisons, to study the human genome, to learn more about how viruses work, and played a crucial role in the development of the polio vaccine.  Although Mrs. Lacks ultimately passed away on October 4, 1951, at the age of 31, her cells continue to impact the world.
