The Coronation Street legend, 69, was given news of her diagnosis just after she relocated to Dublin, having scooped a role on Irish soap opera Fair City.
I'm A Celeb's Beverley Callard has revealed that she won't be attending the live final on Friday night on medical advice - after being forced to quit the show due to ill health.
Beverley Callard broke down in tears as she was forced to leave I'm A Celebrity South Africa in shock departure after falling ill in camp on Tursday night's episode.
The actress admitted she 'didn't know' what the 'weird' update on the disease meant as she revealed she had been called in for another consultation by her doctor.
The upcoming instalment of the spin-off, which premiered earlier this month, will see the comedian take part in Cut Throat Cliff alongside Beverley Callard, Sinitta and Mo Farrah.
Viewers watched on as Beverley and Mo jumped out of a plane from 10,000 ft - all while having to memorise a sequence of animals, which they then had to relay to Scarlett and Ashley.
The South Africa spin-off kicked off on Monday and in unlikely scenes it was Coronation Street star Beverley and former heavyweight David who got into a war of words.
