An oral surgeon has issued a stark warning about a seemingly minor tongue change that could indicate cancer, urging the public to pay close attention to persistent symptoms that fail to resolve on their own.

"One of the most important warning signs is a tongue ulcer or sore that does not heal within two to three weeks," Dr Andrej Bozic, who practises at Dentum, explained.

The specialist noted that many individuals mistakenly attribute these symptoms to trivial causes, such as accidentally biting their tongue or food-related irritation.

But any lingering symptom warrants professional examination. Beyond non-healing ulcers, Dr Bozic highlighted several other symptoms that merit attention.

Unexplained lumps on the tongue, patches displaying red or white colouration, and areas experiencing numbness or discomfort should all prompt concern.

"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.

The oral surgeon stressed that whilst such changes do not necessarily indicate malignancy, they represent clear signals that the body requires medical evaluation.

Dismissing these warning signs as inconsequential could prove a costly mistake, particularly when early intervention remains paramount.

The tongue frequently offers early indications of broader health concerns, with changes often manifesting before other symptoms emerge.

This makes dental professionals particularly well-placed to identify potential issues at an early stage.

"The mouth is one of the easiest parts of the body to examine, and subtle changes can be visible early," he said.

Dr Bozic emphasised that catching oral cancer promptly dramatically enhances both treatment outcomes and overall success rates.

"In cases of oral cancer, early detection is extremely important because it significantly improves outcomes and treatment success," he added.

The accessibility of oral examinations means that vigilant patients and attentive dentists can work together to identify concerning changes swiftly.

Certain lifestyle factors elevate the risk of developing oral cancer, with tobacco use, alcohol consumption and inadequate oral hygiene among the primary concerns identified by medical professionals.

Dr Bozic advised that individuals should seek medical guidance if symptoms persist beyond a fortnight or show signs of deterioration.

"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.

Additional symptoms warranting investigation include trouble swallowing, persistent pain and alterations in tongue mobility.

"People often ignore changes in their mouth because they assume they are minor," he said. "But recognising when something is unusual and acting early can make a significant difference."
