Cancer Cells Parasitize Other Ones to Survive: Study
Cancer Cells Parasitize Other Ones to Survive: Study
Tumor cells missing a critical protein enter neighboring cells to sap their nutrients, then exit those hosts as intact cells, possibly primed to metastasize. Other scholars say it’s too early to know this for sure.
