A routine visit to the dentist led to a life-saving diagnosis for a teenager who had gone believing he just had a toothache.
Ethan Harrison, 19, booked a dental appointment in May 2026 after enduring pain around both his upper and lower right wisdom teeth.
Working as a forklift driver, Ethan initially assumed the discomfort was caused by an infection and that he might simply need his wisdom teeth taken out — an unpleasant but fairly common outcome.
Instead, the check-up took an alarming turn. During the appointment, the dentist noticed something concerning and advised Ethan to see his GP urgently for further assessment.
That observation proved crucial: Ethan had a swollen lymph node. After a GP visit and blood tests, the results triggered immediate action, and he was sent to Chesterfield Royal Hospital to begin treatment without delay.
Ethan, who is from South Wingfield in the UK, was diagnosed with acute myeloid leukaemia — a cancer that affects the blood and bone marrow.
Doctors later warned that if he hadn’t started treatment within four days of the dental appointment, he could have had as little as three weeks to live.
He has remained in hospital recovering from emergency treatment since May 17.
Ethan’s mum, Roxy Bond, 37, said the family feels “incredibly lucky” the illness was caught when it was.
“When the diagnosis came it was very surreal and just very, very unexpected,” she said. “The team at the hospital said if he hadn’t come in he would have only had a few weeks to live.”
She added: “It felt like a story you’d hear about someone else, not your son.”
Roxy said Ethan had been dealing with the toothache for about a month. Alongside that, he’d developed other symptoms including a fever, shortness of breath, and a swollen lymph node that appeared after he returned from a holiday in Cyprus.
“We just put it all down to the tooth thinking it might be infected,” said Roxy, “but then the dentist saw the swollen lymph node and said he needed to be looked at by a doctor.
“We went to the GP, they did a blood test and the results came back 12 hours later. They said his levels were all over the place and we were told we needed to get to A&E immediately.
“We were rushed through at the hospital because the doctors and nurses already knew it was probably leukaemia.”
Roxy said Ethan is expected to go through four rounds of chemotherapy, having already started the first, and he is likely to spend around a month in hospital during this initial phase.
“It could be about a year before Ethan returns to full health, depending on how his body reacts and he’ll be in the hospital more than he’s home during that time,” she said.
Roxy added: “He’s never been in a hospital before and now he’s having bone marrow biopsies, PICC lines inserted and constant blood tests.
“He’s reacted so far with a sense of humour, nothing’s phased him. All he’ll say is, ‘What an inconvenience’.
“We’re a very positive family and he’s been brilliant. I’m so proud of how he’s handling it.”
