I think that the statement "Practice of Medicine" sort makes a clear statment that medicine is an art as much as a science.
Since Oral cancer is not a cancer which is found in a high precentage of the population doctors are not going to think about it first, like they would a lump in the breast. Also there are many things that may intitally mimic the same symptoms of cancer. So they would naturally treat those first. My Oral Surgeon told me that the spot was nothing to worry about but let's just do a biopsy to be sure.Once the diagnois came back told me in 27 years of removing spots from people's mouths he had NEVER gotten this diagnois. I was just lucky because of the location and of course my daily "PET" pushed me to take action.
