Study notes
Why is a painless, long-standing white patch on the lateral tongue taken seriously? The lateral border of the tongue is the highest-risk site for oral squamous cell carcinoma. A persistent white or red patch (leukoplakia/erythroplakia) there can harbour dysplasia — abnormal cell changes that may progress to invasive carcinoma. This is why dental curricula teach systematic visual examination of these sites: early lesions are often painless, and painlessness does not mean harmless.
