How to Block Bacteria in Cancer Cells?

There's a built-in amplification there where you might not necessarily need to infect all of the cells in that tumor.

So one cell picks up some bacterial passengers, some freeloaders, that in some way manipulates the infected cell but makes it then feed all its neighbors so they all get a growth boost.
