Morrissey recalled the moment he learned of his diagnosis, saying you never expect to hear the "C-word".
"It just seems to drift over you. You just say yes, 'Oh yes, yes, yes'. Later, when you're on the stairs by yourself, it triggers in your mind."
Morrissey has had less success with is his ongoing battle with depression, however, which he calls "the black dog".
The former The Smiths frontman admits he wakes up most mornings feeling low, but has stopped taking prescribed medication for his condition, insisting nothing works.
"There is no cure and I think it's part of being a sensitive, open human ... I've been through everything; it's just pointless."
Asked if he has ever considered taking his life, the singer adds, "It crosses everybody's mind. Everybody thinks about it, even people who mistakenly assume they're happy."
