Clinical studies reveal that in India among the cancer patients majority of them are diagnosed and having oral cancer. Practitioners in their study suggest that patients should come forward to diagnose the cancer and start treatment in early stage to avoid complication. The present review aimed to describe the essentials of early diagnosis, pathophysiology, and various conventional and advanced diagnostic techniques available. Past literatures published in journals was reviewed with a focus on oral cancer diagnosis and also critically examined the different tests. Moreover, this paper assessed the value of each test in spotting oral squamous cell carcinoma and also its precursor lesions. It is evident that despite consequent innovation in diagnostic techniques, the burden of oral cancer remains constant. From this study it was found that frequent conduct of awareness programmes about oral cancer and providing low cost screening of oral cancer will help the people to cure cancer.
