The 41-year-old It Feels So Good singer was diagnosed in May last year and had three operations, intensive chemoth-erapy and a recent batch of preventative radiotherapy.
Sonique – real name Sonia Clarke – confessed: "It's all good and they've given me the thumbs up and all of that so I'm just trying not to hang on to that whole thing now.
"I'm trying to just distance myself away from the whole experience as much as possible.
"Rather than thinking I'm on the road to recovery now, I've recovered and it's time to pick up the pieces and move on and forget about that place. You just have to think positive."
But the singer admitted that when she first discovered a lump she put off seeking doctors' advice, and urged other women not to do the same.
She said: "I thought it was a cyst so I'd dismissed it for about four months which is really bad of me. But I suppose no one wants to even admit, or even have that be a problem. You don't want to know the truth.
"But the sooner you do, even if you have just a little suspicion you should check it."
Sonique joined 20 other celebrities, including Kym Marsh, Caroline Quentin, and Danielle Lloyd in re-recording Cyndi Lauper's '80s classic Girls Just Want To Have Fun which was released as a single to raise money for Cancer Research UK.
The singer revealed how when she was diagnosed with breast cancer she thought the worst, but was amazed by the medical care and support she received.
Sonique said: "You just think what everyone else would think. Death. There is no other way you are going think, unless you're an extremely positive minded person, which even I am and I still thought was like 'okay this is a dark road, this is too dark for me. I just don't understand this."'
But she said of the staff who treated her: "Amazing. They were so considerate, attentive, caring, everything. There was not one moment when I was unsure of what was going on, they kept me on top of everything.
Girls Just Want To Have Fun is out now and is being sold exclusively by Tesco and available for online download from iTunes.
