Henrietta Lacks underwent a second course of radiation therapy on March 29, 1951, as her cervical cancer progressed.
On March 29, 1951, Henrietta Lacks received a second round of radiation therapy at Johns Hopkins Hospital as her cervical cancer continued to advance despite initial treatment. Her condition was worsening even as, unbeknownst to her, the cells taken from her original biopsy were thriving and multiplying prolifically in Dr. Gey's laboratory.
This period illustrates the tragic irony at the heart of Henrietta's story: while her own body struggled against an aggressive and ultimately fatal cancer, the cells derived from that same cancer were achieving a kind of biological immortality that would benefit medical science for generations. The stark contrast between her declining health and the flourishing of her cells in culture has become a central element in narratives exploring the ethics of her case.
Her treatment continued amid the medical limitations of the early 1950s, when radiation therapy for cervical cancer, while sometimes effective, could not overcome cancers as aggressive as Henrietta's had become by this stage.
