Abstract The incidence of oral cancer has risen in the past decades and is usually recognised when symptomatic and at a late stage. A premalignant lesion is like smoldering volcano, which if not taken care of, may erupt, often with disastrous consequences. Early detection is therefore very important to reduce morbidity and mortality. A descriptive cross-sectional study was done to assess the prevalence, clinical presentation, and association of various addiction habits in the patients who presented with potentially malignant and malignant lesions of the oral cavity in outdoor clinics of ENT and HNS department of a tertiary care center in Jaipur (Rajasthan). 351 patients of different oral mucosal lesions were examined from August 2019 to January 2020 among which 173(49.2%) patients of potentially malignant and malignant lesions comprise the study group. Clinical findings and detailed history including addiction habits with frequency and duration were noted. Cytological and histopathological examinations were done to conclude the diagnosis. Out of 173 patients of the study group, 146(84.4%) were diagnosed with potentially malignant lesions (PMLs) and 27(15.6%) with malignant lesions (MLs). The most prevalent PML was Oral submucous fibrosis (23%) followed by leukoplakia (7.6%). The most common involved site was buccal mucosa (45.0%) followed by the tongue (26.5%). Tobacco consumption was the most prevalent addiction habit (80%) in the study group. High prevalence of tobacco abuse in patients with potentially malignant and malignant lesions suggested a strong relationship between two. It necessitates & Rashmi Goyal [email protected] 1

Introduction Cancer of the oral cavity ranks among the three most common types of cancer in south-central Asia. In India, the age-standardized incidence rate of oral cancers is 12.6 per 100,000 populations [1]. The international agency for research on cancer has predicted that India’s incidence of cancer will increase from 1 million in 2012 to more than 1.7 million in 2035. This indicates that the death rate because of cancer will also increase from 6, 80,000 to 1–2 million in the same period [2]. It has been estimated that 43% of cancer deaths worldwide are due to tobacco, unhealthy diet, physical inactivity, and infection. A significant number of oral cancers are preceded by precancerous lesions of the oral mucosa, known as potentially malignant disorders in recent years, that consist of a group
