Roxy Jacenko reveals the truth about her cancer diagnosis in fiery 60 Minutes interview.

A fiery excerpt from Roxy Jacenko’s tell-all interview with 60 Minutes has been released, and from the looks of it, the PR mogul remains as unapologetic and defiant as ever, telling reporter Allison Langdon to “change your friends” after it was suggested people found the mother of two’s breast cancer diagnosis timing questionable.

“There’s a problem isn’t there, when you announce that you have breast cancer and people’s first reaction is cynicism,” Langdon says, going on to explain that it’s “normal people out there” who are the ones raising these questions.

“Well they’re not normal Allison,” Jacenko replies, continuing, “Change your friends.”

Set to be aired on Sunday night, the story will focus on Jacenko's breast cancer diagnosis and adjustment to life as a single mum following her husband Oliver Curtis being jailed for insider trading.

The preview includes a number of interview excerpts, as well as personal moments between Jacenko and her two children, Pixie, five, and Hunter, two.

When pushed again by Langdon on the question of her breast cancer diagnosis timing, Jacenko simply responded, "It is what it is. I am the person who has got the cancer, my husband is in jail, and I'm now a single mother. I don't really give a fuck what they think on my timing. "

On the topic of Curtis, who was found guilty of operating an insider trading scheme that ultimately lead to him profiting over $1.4 million, Jacenko said the couple - who were not dating at the time of the scheme's operation - "don't discuss" what happened.

When asked by Langdon if she doesn't want to know what went on, Jacenko replied, "he's got no reason to lie to me."

Curtis was sentenced to two years imprisonment and will be eligible for parole in June 2017.

Jacenko's full interview with 60 Minutes is set to air on Channel 9 on Sunday 21 August.
