What does oral shingles versus oral cancer look like? i'm getting over a mild to moderate case of shingles on right side of my abdomen.

Shingles/COPD/diabet: oral shingles may look like cold sores of the mouth, but cancer of the mouth usually starts as tumor(varies in size from lentil to a bean size) that may ulcerate later..shingles improve in few days and may take a week or two to heal. oral cancer does not heal..shingles usually multiple small superficial sores but oral cancer usually single and deep

Signs/symptoms: See oral surgeon or ENT doc if you have any of these symptoms: Persistent mouth sore, persistent mouth pain, a lump or thickening in the cheek, a white/red patch on the gums, tongue, tonsil, or lining of the mouth, a sore throat, hoarseness or feeling that something is caught in the throat that does not go away, difficulty swallowing/chewing.
