My area of research is Artificial Intelligence (AI) in biomedical image processing. Cancer is a disease in which abnormal cells multiply uncontrollably and cause tissue destruction. Oral Cancer is the 11th most widely common cancer worldwide. Oral cancer risk factors are- Tobacco, Alcohol, Areca Nut, HPV, etc. Oral Dysplasia is precancerous lesions- A growth containing abnormal cells confined to the lining of the oral cavity or mouth. In the dysplasia grading system, cytological and architectural features are combined and assessed to find the degree of oral dysplasia, which is challenging. Cancerous growth can be prevented to a large extent if detected at this stage.
