I am a 58 year old female in fairly good health. A couple weeks ago during a regular dental exam the dentist noticed a small, white sore under my tongue. He thought it might be from a rough edge on a crown that caused a callous. He smoothed down the area and asked me to return for a follow-up if the sore did not go away. It has been two weeks and it has not changed. I've done some Internet research which led me here. There is no pain involved. The sore is on the underside edge of the tongue about 3 teeth from the back. It is white in color and on the small side. The dentist will refer me to an oral surgeon for a biopsy when I see him on the 10th. I should add that I had endometrial cancer a little over 2 years ago with surgery being the only treatment since it was stage 1a. All my follow-ups have been good. Any thoughts, suggestions, advice would be welcome. Thanks in advance.
