Goodness gracious me, so, you have Cancer in your body. OK, lets see how it goes shall we? Let's see how the Cancer develops in your body for a while. Let's just let it fester and grow until we are obliged to do something, oh, by which time it may be too late.
I make no apologies if my post upsets or hopefully makes anyone "Wake up and smell the coffee".
