Playing labslop's advocate here, I'm going to assume that, since cancer can silently become a systemic problem causing an impotent immune response and inflamatory havoc throughout the body, meat from an animal with cancer is probably damaged by those processes, to the point that, even if it is still edible, it may be poor quality. Lab-grown meat, while technically being a tumor, is not going to suffer from the same problem simply because it's not connected to a whole living body.
