A case control study was done to evaluate the risk imposed by various smoking habits in the development of bronchogenic carcinoma. All the consecutive 52 newly diagnosed and histopathologically proven bronchogenic carcinoma patients who had come to the hospital over one calendar year for treatment, were included in the study and 156 healthy by-standers of patients matched for age, sex and socioeconomic status were included as controls. A pretested questionnaire was used to seek information on socio-demographic and smoking habits of cases and controls. A fairly strong association was found between smoking and lung cancer. Out of 52 lung cancer patients, 39 (75%) had consistently smoked and only 55 (35.3%) of 156 controls had smoked. Of 39 smokers in cases, 26 (66.7%) smoked bidis and of the total 55 smokers in control group, 40 (72.7%) smoked bidis. Tobacco smokers on the whole had 5.5 times greater risk of developing lung cancer than nonsmokers (OR: 5.51, 95% CI 2.56 - 12.02; X2 = 23.29; p < 0.001). Bidi smokers had 5 times greater risk of developing lung cancer than nonsmokers (OR: 5.05, 95% CI2.21- 11.7; X2 = 17.68; p < 0.001). The risk increased with the number of bidis smoked per day and the duration of smoking. A comparative risk factor for lung cancer in cigarette as opposed to bidi smokers could not be assessed because of the small number of cigarette smokers in the study population.
