The Sydney publicist will undergo surgery this week to have a portion of the cancerous lump removed from her left breas.
The Daily Telegraph reports that her "partial removal” surgery was originally set to go ahead last month, but was delayed for further testing.
“[The cancer] is larger than first suspected, so more testing is required," the mum-of-two bravely told the publication at the time of the diagnosis.
The Sweaty Betty founder revealed her cancer diagnosis in July, just three weeks after her husband Oliver Curtis was sentenced to a year in jail, for conspiring to commit insider trading in 2007 and 2008.
This week, he celebrated his first birthday behind bars.
To mark the somewhat tainted occasion, the 36-year-old shared a video of her two little ones wishing their daddy well.
“Unlikely you will get this but you might hear about it,” she captioned beside the video, which you can see for yourself in the player below.
Over the weekend the blonde beauty, who is now the sole carer for the couple’s two children Pixie, four, and Hunter, two, was spotted at Sydney’s iconic Taronga Zoo, accompanied by Nine Network’s 60 Minutes camera crew.
The upcoming episode is expected to focus on the young family’s tough start to 2016, giving viewers a rare, candid look into the couple’s seemingly glamourous life.
And while it’s no doubt been a rocky few months, the brave businesswoman is getting through the storm with the help of her mother, who battled her own breast cancer a decade ago.
“Having my mum by my side who has suffered breast cancer and a mastectomy and come through fighting fit also makes things easier,” she admitted to The Daily Mail.
“Fear isn’t an option, I have my Pixie and Hunter to look after so a clear mind and a proper plan of attack to get over this is the only thing that I think about.”
