'I'm a dentist - this subtle sign on your tongue could be cancer'

A subtle change on your tongue that many people dismiss could be an early warning sign of something far more serious, a dentist has advised . Experts say persistent tongue symptoms are often ignored or mistaken for minor irritation, but in some cases they can signal oral cancer or other underlying health conditions . Dr Andrej Bozic, oral surgeon at Dentum , said the key sign to watch for is a symptom that does not go away. He said: "One of the most important warning signs is a tongue ulcer or sore that does not heal within two to three weeks. “Many people assume it is something minor, like biting the tongue or irritation from food, but anything that persists should always be checked.” He said other warning signs can include unexplained lumps, red or white patches, or areas of the tongue that feel numb or painful. “These symptoms do not automatically mean cancer, but they are signals that something is not right and should be assessed by a professional,” Dr Bozic said. According to the expert the tongue can often provide early clues about what is happening in the body, as changes may appear there before other symptoms develop. Dr Bozic said this is why dentists are often among the first to spot potential problems. “The mouth is one of the easiest parts of the body to examine, and subtle changes can be visible early. "In cases of oral cancer, early detection is extremely important because it significantly improves outcomes and treatment success.” He added that lifestyle factors can also play a role in increasing risk. He said: "Smoking, alcohol use and poor oral health are among the key risk factors we look at when assessing patients." When to seek advice While many tongue issues are harmless and temporary, experts say persistence is the key factor that should not be ignored. Dr Bozic said people should seek advice if a symptom lasts longer than a few weeks or begins to worsen. “If a sore, patch or lump on the tongue does not improve within two to three weeks, it is important to have it examined,” he said. He also advised paying attention to symptoms such as difficulty swallowing, ongoing pain or changes in how the tongue moves. These may indicate that further investigation is needed, even if the symptoms seem mild at first. Dr Bozic said awareness is crucial, as many patients delay seeking help. He added: "People often ignore changes in their mouth because they assume they are minor. But recognising when something is unusual and acting early can make a significant difference."
