The three-part series, simply called Kylie - created by the team behind Netflix's David Beckham documentary, Beckham - will explore how the Australian singer became one of pop's biggest stars.
It features footage from her childhood and time in Neighbours, as well interviews with friends and family including her former co-star Jason Donovan, sister Dannii and musician Nick Cave.
The series also shows both Kylie and Dannii talking about her cancer ordeal.
Speaking at a Q&A in central London ahead of the documentary's release, Minogue said making it had been good for her and had come "from the heart".
"There's light and shade for sure," she said of the film, adding: "We're all human."
Asked what she hoped her fans would understand about her after watching the film, she said: "I can imagine that fans and maybe even broader than that … maybe that's one of the reasons that I have this relationship with my fans and the broader audience, is they can see, don't know if I tried to do this, again it's very weird to say this about myself, but I'm not invincible.
"I can get the job done and I can shine, hopefully.
"But I think that, I don't know, that they understand that you could be me, we could co-exist."
Minogue was asked about the public scrutiny and misogyny she had faced during her career, which is featured in the film.
"There's always a lot of talk about how much I've changed," she said.
"We all change through life, and grown and developed, and certainly that's evident, as an artist, like I was famous before I knew what I was doing, so you know, and there came a lot of the criticism and the hardship with that, but what's illuminating to me is, in so many ways, I haven't changed.
"Like, the way of dealing with stuff from that time that you're talking about is kind of how I do it now, like I read the room, do what I have to do, feel the fear and do it anyway."
Minogue was diagnosed with breast cancer in May 2005 aged 36, and underwent a lumpectomy and chemotherapy in Paris, before being given the all-clear in 2006.
News coverage of her cancer diagnosis caused an unprecedented increase in bookings for mammograms, referred to as the "Kylie effect".
Series director Michael Harte said it was like a "beam of light" had walked into the room when he first met her.
"She literally bounced into the room," he said.
"I remember coming in and there was an energy to Kylie and I was like, wow, I hadn't experienced this before. It was just intoxicating."
He said making the film had been "two years of joy" and he had been struck by her sense of humour, hard work, "extraordinary" talent but mostly by her resilience.
Kylie premieres on Netflix on Wednesday.
