Key cancer symptom you'll only spot when you brush your teeth

People are being urged to be vigilant for a 'red flag' cancer symptom that can only be spotted when brushing your teeth. This comes as mouth cancer cases in the UK have reached an unprecedented high, exceeding 10,000 cases for the first time.

The Oral Health Foundation's new data reveals that 10,825 new cases of mouth cancer are diagnosed annually in the UK, marking a 133% increase over the past two decades. The charity's 2024 report shows that 66% of mouth cancers in England are diagnosed in men, with those aged over 50 accounting for 90% of all cases.

These findings have led health experts to issue a warning about mouth cancer symptoms to aid early detection. The primary symptom is one that can only be noticed while brushing your teeth.

According to the Oral Health Foundation, one-in-three (31%) of all mouth cancer diagnoses occur on the tongue. The crucial warning sign to watch out for is any white patches on your tongue or inside your mouth.

The second most common sign is found in the tonsils, which account for one-in-five (22%) mouth cancer diagnoses, while other affected areas include the lips, gums, roof and floor of the mouth, and the inside of your cheeks. Mouth cancer can cause persistent mouth ulcers, red or white patches in the mouth, and unusual lumps or swellings in the mouth, head, or neck, reports the Express.

Dr Nigel Carter OBE, Chief Executive of the Oral Health Foundation, has issued a stark warning: "While many types of cancer are declining, mouth cancer continues to surge. Smoking and excessive alcohol consumption remain significant risk factors, but we are seeing a growing number of cases linked to the human papillomavirus (HPV) and other emerging causes. Mouth cancer can affect anyone, and the impact on a person's life can be devastating."

He emphasised the need for greater public awareness, stating, "We need to raise awareness of the symptoms, the risk factors, and most importantly, the importance of early detection. Too many cases are diagnosed too late, often at the most advanced stage. This needs to change."

The NHS advises vigilance for any signs of mouth cancer, which can include a persistent mouth ulcer lasting more than three weeks, red or white patches inside the mouth, lumps in the mouth or on the lip, pain or difficulty swallowing, changes in speech or voice, a lump in the neck or throat, and unexplained weight loss. While these symptoms may be indicative of other conditions, the NHS recommends seeking medical advice from a GP or dentist as early detection can significantly improve treatment outcomes.

Prevention strategies for mouth cancer involve maintaining a healthy lifestyle, including eating five portions of fruit and vegetables daily, regular exercise, limiting alcohol intake to less than 14 units per week, and avoiding smoking or chewing tobacco to reduce risk.
