He told the Liverpool Echo that he got diagnosed with eye cancer two years ago in December, which he has never heard of, he was treated just after Christmas that year.

‘It went well but the biopsy looked at his genes – if you’ve got a certain type of gene, there’s quite a high chance of cancer returning, and when it does, it usually is in the liver.

‘Then in December last year, something showed up. he had to go back. It confirmed it had spread. He went to a consultant just after Christmas and it was confirmed that his cancer was untreatable.’

Allan said the news was very tough for him, his wife Joyce, and daughters Beccy and Rachael.

‘Watching my wife and kids cry, seeing other people cry, that makes me more emotional,’ Allan said.

Allan has taken time off from his comedy work and with his church, with the talent show contestant putting on just two gigs in the last two years.

He is now looking for fund specialist treatment for himself which isn’t available on the NHS.

Chemosaturation therapy, which ‘saturates’ the liver and targets tumours, costs £50,000, and Allan has set up a GoFundMe page to raise funds.

He wrote: ‘I’m fundraising for life saving cancer treatment not available on the NHS. I was diagnosed with ocular melanoma 2 years ago and was treated successfully but unfortunately it has now metastasised into my liver and is incurable.

‘I’ve been given 12 months but could extend this by receiving Chemosaturation Therapy, directly to the liver (Delcath).

‘This would give me some valuable time with my family, friends and new 3 month old grandson, Albie. The treatment costs £50,000 per dose and I’ve been advised that I’ll need at least 3,’ Allan wrote.
