In India tobacco is consumed in smoked and smokeless form. It is a proven fact that tobacco consumption leads to oral cancer. The pre cancerous lesions can be detected for up to 15 years prior to their change to invasive carcinoma. Intervention at this stage may result in regression of the lesion. In spite of knowing the history of tobacco addiction, the health care personnel do not make an attempt to examine the oral cavity of the patient and counsel on the various ill effects of tobacco on health. Hence the department of Community Medicine conducted a cross-sectional study in individuals (consuming tobacco in any form) attending the outpatient department of urban health training centre located in Pratiksha nagar, Sion, Mumbai with following objectives 1) To assess the awareness of ill effects of tobacco consumption on health 2) To assess proportion of patients willing to quit consumption of tobacco.3) To clinically examine the patients for oral precancerous lesions. 4) To assist patients willing to quit tobacco consumption.5) To teach oral self examination.40 subjects (75.47%) were aware of the fact that tobacco consumption leads to ill effects on health. On oral cavity examination of the study subjects, 3(5.66%) were detected with leucoplakia.
