Why can’t you just cut off cancer cells?

Question

I know there’s a reason, but I don’t know what it is.

Answer 1

You can, and we do. But the problem with cancer is that is grows really fast and little bits break off and float around the body, then those little bits start growing in other parts of the body.

When that happens then it becomes really hard to even find all the cancer, let alone cut it out. That’s when we gotta fill the person with enough poison to kill the cancer, but not enough to kill the person.
