The soap has confirmed that Moira has a type of brain tumour called a meningioma, which has caused her mood swings, erratic behaviour, and memory loss over the last few weeks.

Although Moira’s type of tumour is not cancerous, it still poses danger to her life. In upcoming scenes, Moira will find out more about her treatment options.

As she prepares to meet with a neurologist, Moira starts to feel fed up with members of her family repeatedly interjecting their thoughts on possible treatment.

Moira and Cain eventually will meet with a neurosurgeon who suggests the best option may be to “watch and wait” for now, to see how the mass on her brain develops.

Cain is furious over the neurosurgeon’s reluctance to rush Moira into surgery, and while his feelings are understandable, he’s not looking at the bigger picture of Moira’s quality of life.

However, Cain is concerned about noticing more signs of Moira’s deterioration as the couple tries to figure out what their future could look like.

These scenes will air next week.

Emmerdale producer Sophie Roper and the soap’s writers have worked closely with charities brainstrust and The Brain Tumour Charity to create a “realistic and authentic depiction”.

“I feel really fortunate to be trusted with such a challenging storyline,” Natalie J Robb has said.

“Moira and her family have an extremely challenging time ahead, and I’m hoping I can portray it in a truthful way that does justice to all the people who are really suffering with a brain tumour.”
