The 19-year-old was re-admitted just 10 days after being discharged following a ‘miraculous’ improvement in his condition.
The brave campaigner took to his Facebook page, writing: ‘Unfortunately today I've ended up back in hospital. I had some breathing difficulties starting last night and after going to A&E have been admitted back to a ward for monitoring.’
‘I've still got the cough, then quite quickly developed a wheeze in my breathing and breathlessness upon any physical exertion.’
Stephen then eased his follower’s concerns: ‘There's no immediate panic and I'm currently quite stable - I have been put on nebulisers and other meds which are currently helping my symptoms hugely.’
He continued: ‘The doctors think there may be something restricting my airway again, they're not sure exactly what yet though (tumour regrowth, infection, inflammation, are all potential reasons mentioned), but are currently discussing the possibilities and my scan results to decide what to do next.’
The teenager from Staffordshire revealed that he was forced to cancel TV appearances due to the reappearance of his symptoms.
He wrote: ‘I had a few cool things planned to attend today, then tomorrow was due to appear on the telly on BBC Breakfast News... I understand my health is the obvious priority though and have had to cancel.
He positively added: ‘Fingers crossed the issue will be resolved and that I'll be out of hospital soon - I'll keep you all updated with how I'm getting on.’
With the help of some celebrity friends, Stephen (who's cancer is terminal) has so far raised over £3 million for Teenage Cancer Trust after originally setting out to raise £10,000.
