I am wondering if the following method (or similar variations) for treating cancer exists and if so if it works.
The metod is to deliver an ”antidote” to all cells (or all cells of a specific type) in the body, via virus,liposomes or diffusion. Then you wait for the cancer cells to divide which should lower the concentration of the antidote in the newly divided cancer cells. Then you inject the ”poison” into all the cells, the ones which already have the antidote in high enough concentration survive, the ones who doesn’t die.
When looking around to see if this exists all I found were articles about how to target cancer cells specifically, nothing about targeting all cells and using the fact that cancer cells divide quicker to distinguish between them.
