Exfoliative cytology for oral cancer

What is exfoliative cytology?

With this approach, a suspicious area is gently scraped to collect a sample of cells. These cells are placed on a glass slide and stained with dye, so that they can be easily viewed under a microscope. If any cells appear abnormal, a deeper biopsy will be done. This technique is very easy to do, allowing even minimally abnormal areas to be examined, which can help with early diagnosis.
