Biopsies play a vital role in identifying and assessing abnormal growths, suspicious areas, or oral diseases such as oral cancer. If the dentist finds a suspicious area, she may take a small tissue sample from your mouth and send it to the BC Oral Biopsy Laboratory where it is analyzed by pathologists for a definitive diagnosis. Dental biopsies are essential for early detection, accurate diagnosis, and effective treatment planning to ensure the best possible oral health outcomes for patients.
