The early signs and symptoms of oral cancer may include a mouth ulcer that does not heal within two weeks, red or white patches, unexplained bleeding, numbness, swelling, or a lump inside the mouth. Other early signs and symptoms of mouth cancer include difficulty chewing, swallowing, speaking, or moving the tongue. The signs and symptoms of mouth and throat cancer may also involve persistent hoarseness, ear pain, throat discomfort, or a neck lump. These signs and symptoms of oral cancer do not always indicate cancer, but they require proper evaluation. Dr Smit A. Desai carefully examines suspicious oral changes and recommends suitable tests when needed. Conclusion Do not ignore any unusual mouth or throat change lasting over two weeks. Early diagnosis supports timely treatment and better outcomes.
