Dr. McDonald is the expert for diagnosing cancer of the head, neck and mouth. The Oral Cancer Foundation estimates that close to 42,000 Americans will be diagnosed with oral or pharyngeal cancer this year. Oral cancer’s mortality is particularly high, not because it is hard to detect or diagnose, but because the cancer is often discovered late in its development. Your family dentist or Dr. McDonald is in the best position to detect oral cancer during your routine dental examinations.
