Iron Maiden frontman Bruce Dickinson talked with Skavlan Show and revealed his feelings when he got diagnosed with throat cancer. He said (transcriped by Blabbermouth):

Your voice is a muscle, like anything else, and as long as you don’t abuse it and you use it correctly, then it will last. I’m not a great believer that a voice is just about singing. A voice is a tool for communication.

And as a singer, all you are, really, is a storyteller, and it just so happens that, obviously, with my voice I tell stories a particular way, but if you’re Leonard Cohen, you have a different voice and you still tell great stories. When I got diagnosed with throat cancer three years ago, the thought occurred to me I might not be able to sing again.

Thankfully, that was not the case. But I did think about it, and I thought, ‘You know what? Even if my voice changed completely, it still doesn’t mean I can’t tell stories.’ Maybe I’d have to tell them a different way. Maybe I couldn’t do them with Iron Maiden. But it still doesn’t stop you… If what you want to do is tell stories, then you find a way to do it.

Talking is disaster for the voice. Because when you sing, all the muscles in the voice are used in completely the opposite way to when you talk. So I’m talking to you now and I’m using everything from here [points to his throat] down. Well, when I’m singing, I’m using everything from here up.

So all it is is… Think of it like an organ pipe – basically, lots of rest, sleep, plenty of water, keep it hydrated. Don’t go out yelling in pubs after the show.”
