Cancer invades even more, it is a forever thing

Cancer had already invaded my tissue, then it invaded my every waking thought. Now it has invaded my last sanctuary, sleep. I had a nightmare about it. Cancer never stops. This is a forever thing, even if they get it out right now, it will never be gone, it can come back (high recurrence rate for my type of cancer). It messes with *everything* in your life *forever*. This will never go away.
