Cancer starts as a single rogue cell whose mutations then trigger aggressive growth, damaging the health of the organism. But if cancer cells were accumulating harmful mutations faster than they could be purged, wouldn't the population eventually die out? How do cancer cells avoid complete genetic meltdown?
To try and find answers, researchers in
a recent study probed the most famous cultured cancer cells, HeLa cells, isolated from cervical cancer victim Henrietta Lacks in 1951 and becoming the first immortalized cell line.
