Why does chemotherapy kill cancerous but not normal cells? Most cancer biologists would answer this by stating that chemotherapy is selectively toxic to proliferating cells, and that cancer cell proliferate more than normal cells. Not exactly - there's a lot more to it.
Many normal tissues, like bone marrow and gut cells are actually more proliferative than even the most aggressive cancers. E.g. pro-myelocytes have a doubling time of around 17 hrs whilst even aggressive epithelial tumors double every 2-3 weeks or so.
So while many chemotherpeutics (e.g. #Temozolomide for GBM) show extensive myelotoxicity as a side effect, clinically useful ones are able to kill cancerous cells more efficaciously than normal ones, even if the latter proliferate faster, like pro-myelocytes.
