Chris Fleming from Holywood, Co Down, was diagnosed with mouth cancer on 17 December 2025. The diagnosis followed dental issues that began in summer 2025.

Fleming had two teeth removed due to mild discomfort rated at three out of ten. Weeks later, discomfort appeared near a wisdom tooth. After its removal, the area failed to heal properly, leaving a small flat spot.

Fleming returned to his dentist for a follow-up and was urgently referred to the School of Dentistry. A biopsy confirmed the cancer, despite Fleming having no typical risk factors such as smoking or heavy alcohol use.

In early January 2026, Fleming began treatment at Ulster Hospital under Consultant Oral and Maxillo-Facial Surgeon John Hanratty. Fleming described the hospital care from consultants and nursing staff as highly professional and supportive.

Hanratty listed mouth cancer signs including ulcers lasting over three weeks, white or red patches with pain, or lumps in the mouth, oral cavity, or neck. He noted higher prevalence linked to social deprivation, poor diet, alcohol, and smoking.

Hanratty stated early detection improves outcomes, but only 20 percent of cases present early, with 45 percent involving large or spread cancers leading to poorer results. He advised checking with a dentist or GP for any issues.

Fleming urged others to seek checks for persistent mild discomfort or non-healing areas, emphasizing early diagnosis makes a difference.
