Aherne shared a joke from the time of her chemotherapy treatment at the Cecilia Centre at Wythenshawe Hospital, involving Royle Family co-star Ricky Tomlinson who played her on-screen father.
Aherne said: "The cleaner came in one day, she went, 'Oh, I knew you were here, they told me you were here, oh that's great, I love the Royle Family but I would've much preferred it to be Ricky in that bed!'
"She was wishing lung cancer on Ricky Tomlinson!"
