Henrietta Lacks was a poor black tobacco farmer who was diagnosed with cancer in 1951. A doctor examining her at the time, removed a tumor from her body without her consent or knowledge and sent it into a lab for further investigation. Her cells were remarkable; they kept on dividing and living and would never die. These cells became one of the most important tools in medicine and greatly contributed to the development of the polio...
