Design of lung cancer specific questionnaires for the south Indian population

The lung is an essential organ for humans for respiration, which often gets affected by diseases. Lung diseases range from mild, like a cold, to life- threatening diseases, like asthma, tuberculosis, cancer, etc. It can be identified in patients by their symptoms through questionnaire. Among all the lung diseases, cancer is the most dangerous, and may be fatal. The survival rate of the patient with lung cancer depends on its early detection and proper treatment. The available questionnaires for screening tools, developed and validated for use in lung cancer detection studies, are reviewed in this paper. These studies show that the available questionnaires for lung cancer detection need modification to meet the needs of the people in the south Indian region. This work is aimed to design questionnaires for pre-diagnosis of lung cancer and their stage-wise detection, which may be useful in designing screening tools, which help the physician to diagnose the disease.
