Speaking in an interview with Fox News, Iron Maiden frontman Bruce Dickinson explained how he coped emotionally with tongue cancer in 2015. He said:

“I guess I had to take a long, hard look at myself… So what am I going to be like? How am I going to be just grumpy, aggressive, snappy and [feel] sorry for myself?

I thought there must be a better way of doing it. Because I actually thought of getting angry with it, like in my head. Like, I would visualize angry things. Like sticking pins in all these nasty cancer cells. And I remember one evening going, that’s absolutely exhausting. I mean, why exhaust yourself? The chemo and radiation is already doing that. That’s sticking plenty of pins in.

Why don’t you just look after yourself and feel good about yourself and just get on with it? And behave as if this were an aberration and not a permanent fixture.

Maybe that’s the best way of dealing with it. And that was my choice… And I’m not a terribly negative person in general.

So the idea of being wholly negative for six months went completely against my personality… I have to think of it in a positive way. So that’s where it came from.”
