New analysis by Public Health Wales has shown that deprivation continues to contribute significantly to the number of oral cancer cases and survival across Wales.
The analysis of the Number of Oral Cancer Cases in Wales 2025 reveals that people living in the most deprived areas of Wales are more likely to be diagnosed with oral cancer, and less likely to survive five years after being diagnosed, compared to those living in more affluent areas.
Late stage diagnoses remain one of the most pressing challenges. Most cases in Wales are diagnosed at stage three or four, which means that the treatment is more complicated and the results are often worse.
Professor Paul Brocklehurst, Public Dental Health Consultant at Public Health Wales, said:
"Oral cancer is one of the few cancers where we can often see or feel the early signs ourselves, but too many people wait too long before seeking professional advice. We encourage anyone who notices something unusual in their mouth, such as an ulcer that won't heal, a red or white spot, or a lump, to see their dentist or GP as soon as possible."
Smoking and drinking remain two of the biggest preventable risk factors for oral cancer, along with human papillomavirus (HPV) infection in some cases.
The report also shows that oral cancers continue to disproportionately affect men. The ratio is that two men are diagnosed for every woman.
Oral cancer still mostly affects the tongue and oropharynx, and five-year survival rates for those diagnosed in advanced stages remain below fifty percent.
The report emphasizes the importance of oral cancer prevention, early detection, and lifestyle choices towards reducing the risk. The Oral Health Foundation recommends taking a number of steps to reduce the risk of oral cancer, including:
Stop smoking and avoid using all tobacco products
Drink alcohol within the recommended limits
Eat a healthy diet full of fruit and vegetables
Visit your dentist regularly for check-ups
Put sunscreen on your lips when you're outdoors
Professor Brocklehurst added:
"Although there are improvements among some groups, too many people are still diagnosed when the cancer is already well advanced. Detecting cancer early saves lives and simple changes such as stopping smoking, reducing the amount of alcohol consumed, and having regular dental check-ups can significantly reduce your risk of getting cancer."
Public Health Wales is encouraging everyone to be aware of their mouths during Oral Cancer Action Month and to check their mouths for any changes regularly.
