The oral cancer examination is completely painless. Dr Sandhu will look for abnormalities and feel the face, glands, and neck for unusual bumps. Lasers may be used to highlight pathologic changes, and can “look” below the surface for spots and lesions invisible to the naked eye. Some of the signs that will be investigated are red patches and sores. Red patches on the floor of the mouth, or the front of the tongue, and bleeding sores which fail to heal easier, can be indicative of cancerous changes. Leukoplakia is a hardened white or gray, slightly raised lesion that can appear inside the mouth, and may be cancerous. Signs of these will be examined as well. Finally, soreness, lumps or the general thickening of tissue anywhere in the throat or mouth can signal pathologic signs, and will be examined.
