The news comes just three weeks after Roxy’s husband Oliver Curtis was jailed for insider trading.
“The timing is extraordinary,” the 36-year-old mother of two told The Daily Telegraph.
“What I have experienced in the past three weeks is the most shocking thing I have ever experienced. I don’t think there is anything that could shock me more now.”
Roxy discovered a lump in her breast last week. She was due to have it removed yesterday but the surgery was delayed because the tumour is larger than it initially appeared to be so requires more testing before doctors decide how to treat it.
Roxy also revealed she had been forced to tell her husband over the phone.
Roxy and Oliver have two children together Pixie, four, and Hunter, two.
