Tobacco smoking is the most common risk factor for lung cancer. But a significant proportion of lung cancer occurs in non-smokers. Indoor pollution due to domestic fuels has been recently implicated as a causative agent in lung cancer especially in women. We conducted a case control study to find out the role of domestic cooking fuel as a risk factor for lung cancer in Indian women.


In a case control study 67 women with proven lung cancer were recruited. Forty-six females having a non-malignant respiratory disease constituted the control group. The patients and controls were asked about the exposure in various cooking fuels using a questionnaire.


There were 50(74.6%) non-smokers and 17(25.4%) smokers among the female cancer cases (p = 0.016). Adenocarcinoma was the commonest histological type of malignancy (n = 26, 38.8%) in the whole group and was the predominant form in the non-smoking females. Tobacco smoking was the most important risk factor for lung cancer with OR of 4.87 (95% CI 1.34-17.76). Among non-smokers out of all the cooking fuels the risk of development of lung cancer was highest for biomass fuel exposure with an odds ratio of 5.33 (95% CI 1.7-16.7). Use of mixed fuels was associated with a lesser risk (OR = 3.04, 95% CI 1.1-8.38).


This study indicated that domestic cooking fuel exposure is an important risk factor in the causation of lung cancer among women in addition of exposure to tobacco smoke.
