What is the most appropriate initial communication to a patient when you discover a suspicious oral lesion that may be malignant?

The dentist has an ethical duty of veracity (truthfulness) and must communicate findings honestly without over-reassuring or alarming the patient. The correct approach is to explain that the lesion has suspicious features that require biopsy for definitive diagnosis, and that you cannot confirm or rule out cancer without histopathological examination. Telling the patient it is definitely not cancer (option b) would be dishonest if the lesion is suspicious. Telling them it is definitely cancer before biopsy (option c) is also inappropriate. Saying nothing violates the duty to inform. Maintaining professionalism and sensitivity while scheduling an urgent biopsy is the standard of care.
