As another layperson who only has a college freshman-level understanding of Biology 101, I don't think that's going to be simple.
Immune cells look for -expressions- on the surface of a cell to tell them whether a cell is wonky or not. Typically, these are proteins. These proteins are encoded by DNA, yes, but it's not going to be as simple as diffing the DNA between a regular cell and a cancerous cell because a simple diff like that won't tell you what will get expressed as a key cancer cell surface protein.
DNA gets interpreted as mRNA which then acts as instructions to build long strands of amino acids. These amino acid chains then fold (in hard to calculate ways) into proteins. There's a whole set of other machinery in the cell that regulates how those proteins behave once they're constructed.
TLDR, there's multiple compilation steps to go from a DNA to protein, and then a whole host of runtime monkeypatching to get proteins from A to B.

Shit's complicated unfortunately :/
