I agree whole heartedly with your observation that ignoring cancer doesn’t make it go away. I’ve seen too many examples of this and similar things to argue. This points out one of the often misunderstood and poorly explored aspects of attention: Unconscious attention. Just because we ignore something consciously doesn’t mean we aren’t in a constant state of unconscious attention upon it. The best way to check where these “hidden attentions” are is to simply explore the things we want or don’t want in our lives, or the world, and notice what sort of emotional reaction happens in the body and the subsequent thoughts, beliefs, or behaviors, that follow. If we do this, and find we are anything but emotionally neutral and open to possibilities or options, then there is definitely some background process running, unexamined. I share all this not as a prescription, but as an axiom. It’s a starting place. To the degree that anyone or anything in the world can trigger me, is the degree that I am shackled and enslaved by that. My goal is complete sovereignty, to choose the directionality of my life.
