The Sweaty Betty PR mogul told Daily Mail Australia that she received the worrying diagnosis last month, shortly after her husband Oliver Curtis was released from his one-year prison sentence.
"I had my 12-month check up just three weeks ago, it was a scary time as there was another lump in the same breast," she told the publication.
"It meant another core biopsy and further tests but I got the all clear last week which was a huge relief."
Roxy said that she now has to have MRIs, mammograms and ultrasounds twice a year due to her age. She's also revealed that she is taking the "cancer blocking" medication Tamoxigen daily for the next ten years.
She revealed her husband Oliver reminds her to take the medication every single day.
"We don’t talk about it, though he nags me every single morning to take my medicine," she said. "I don’t know why but I seem to forget unless nagged."
Roxy opened up about her diagnosis, telling the publication about the difficulty of breaking the news to Oliver when he was just three weeks into his sentence.
"It was a very, very hard thing to tell him given he wasn’t in a position to be able to help," she said. "Delivering the news over a six minute phone call is something I will never forget, and I doubt he will either – he just cried."
"I wanted to make sure my life remained as normal as it could for my children," she continued. "Already life was in total disarray. I had gone from having a husband at home to sitting through a two-week Supreme Court trial, on to jail time, and then cancer. I almost think I was forced into just getting on with it, there was no shoulder to cry on, it was me and the kids, it was them realistically that made me focus and keep on going."
We're wishing Roxy all the best as she continues her recovery.
