Her daughter, Nico, went on a murderous rampage and died in the fairground fire last October, and her father, Patrick Blake, died at Nico’s hands following his motor neurone disease diagnosis.

Sienna thought she had found a solid home with Warren, even after trying to kill his son in revenge for Warren not saving Nico in the fire (Hollyoaks is SO complicated at times!).

But as she happily prepares for their impending arrival, she has no idea Warren is plotting to take the kids away from her once she gives birth as well as having an affair with her nemesis Grace Black.

The soap’s bosses have reportedly been working closely with Macmillan Cancer to portray the storyline accurately.

And Anna Passey, who plays Sienna, has spoken to a survivor who was diagnosed with cervical cancer during her own pregnancy.

The Daily Star Sunday quotes a Hollyoaks source as saying: “Sienna’s cancer storyline is going to be one of the biggest of the year.

“When she finds out she has the life-threatening disease, her first thoughts are for her unborn babies.

“It’s a cruel twist considering everything she’s been through.”

The mum-to-be then faces the horrendous decision as to whether to undergo treatment or wait until after her babies are born, putting her life in even more danger.

“It’s a huge decision for her to have to make,” the insider continued. “It’s a heartbreaking and difficult time for her.

“Anna has spoken to a cancer survivor and the writers have been working closely with Macmillan to make sure they get the storyline right.

“It’s going to be an emotional rollercoaster for Sienna as she comes to terms with her diagnosis.”
