Exfoliative cytology for oral cancer
Oral cancer detection using exfoliative cytology can be challenging and some cancers may be missed, or may be confused with abnormal but non-cancerous cells, and so a biopsy will be needed to make a definitive diagnosis.
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.
