One woman born in the 1920s is the source of trillions of cells used in medical research all over the world. Henrietta Lacks died in 1951 from a virulent cervical cancer. A sample of those cancer cells was taken at the time and the way they behave has changed medical science forever 鈥� contributing to everything from the polio vaccine to drugs for Parkinson鈥檚 and Alzheimer鈥檚 disease.
