There is a history of gov/pharma running dangerous medical expts on the poor, but Henrietta Lacks isn't an example of this. Henrietta Lacks is an example of dubious / unethical science, but not dangerous experiments. Tuskegee Syphilis Study - Wikipedia would be or the US Army's various drug experiments, eg LSD would be better examples.
If anyone else is reading: Lacks was a black woman, who had a tumour biopsy taken and the cells cultured. These cells had the senescence genetics knocked out I guess, meaning they were "immortal", but otherwise normal. This meant cell biologists had a perfect strain of cells to work on, which they did, and that strain was called HeLa. I think I worked with HeLa cells in a past life, I forget what strains I used. HeLa cells are really important in medical science though, and have been used in virtually every study when I used to read this stuff.
But, it wasn't dangerous to Henrietta, she went in for a cervical cancer test(?) which I assume came up positive, and they did whatever they could for her. Presumably not much, since she was black, American, and probably poor, and not able to pay for proper health care.
Henrietta didn't know about this, she never gave consent, or was told about this stuff, nor did anyone give her or her relatives any money. So, it's dubious, but it wasn't dangerous to her.
