A dentist has warned that thousands of Brits may be unknowingly living with mouth cancer after a "healthy" dad-of-seven died from the disease.
Alan Birch, 37, lived a healthy, active lifestyle and did not drink or smoke but died from an aggressive form of mouth cancer in April.
The self-employed plasterer, from Wirral in Merseyside, was diagnosed with mouth cancer in 2018, and had to have 90 per cent of his tongue removed, Liverpool Echo reports.
Despite Alan undergoing both radiotherapy and chemotherapy, the cancer returned each time and specialists told his devastated family there was nothing more they could do for him.
