I agree that a biopsy is necessary and simple. My husband�s oral surgeon didn�t even deaden the area. He took a quick swipe with a sharp scalpel and it was done in less than 2 seconds. However, I suggest that you have it done by an ENT. That way it will be cover by your health insurance. We paid the $937 biopsy cost plus the pathologist�s fee out of pocket because our health insurance did not cover our oral surgeon�s fees. Call your insurer first!
