Minogue: 'I Was Misdiagnosed'
The 39-year-old began feeling unwell while she was in the middle of the Australian leg of her 2005 Show Girl tour.
Minogue saw a doctor and went straight back to work after being told she was perfectly healthy.
But several weeks later the singer later found a suspicious lump in her breast and, after consulting a different doctor's opinion, she was diagnosed with cancer.
Following a year of treatment, Minogue has now made a good recovery, but the experience has made her aware that medical tests are not always accurate.
During an appearance on Ellen DeGeneres' talk show, the star urged other women to get a second opinion from their doctor if they suspect they might have the condition.
She says, "Because someone is in a white coat and using big medical instruments doesn't necessarily mean they're right. I don't want to say that to frighten people but that's just a fact.
"I had just had a mammogram and they didn't find anything and a couple of weeks later I found a lump. You must follow your intuition and if you have any doubt go back again."
