Disclaimer: I’m not a scientist, but I want to be.

For things like cancer cells which from a cell surface perspective, can look a lot like healthy cells, I don’t know how one only modifies DNA/RNA expression in only cancer cells. It would have to be all cells with maybe some cellular diagnosis logic in the DNA/RNA itself. Even then cancer evolves. It would have to done multiple times with something like cell descendents information.

Targeting doesn’t have to occur at the cell surface does it?

Perhaps something like introducing tumour suppressor genes to every cell. They’ll have no effect on healthy cells yet detect “badness” in cancerous cells and terminate them.
