A biopsy is nothing more than the partial or total removal of a soft or hard tissue sample. This sample is sent to an oral pathologist for evaluation. The pathologist will send a report describing the types of tissue found and any necessary actions needed. Most time the lesion is of no concern or benign, usually the result of trauma. In the case of cancer, the patient will be referred to a specialist.
If you have unexplained lesions that has changed in the past 10-14 days or a sore that has not gone away in the past 10 -14 days; you should have it examined and possibly biopsied for peace of mind.
