... ile of the lung cancer in hilly region of West Bengal. Materials and Methods: We performed a retrospective analysis of histopathologically proven cases of bronchogenic carcinoma who attended in our hospital in the department of chest and Radiotherapy from January 2015 to December 2017. Results: Our study included 242 patients with confirmed cases of Primary lung cancer. Male to female ratio was 6.12:1. The common age group being 41-60years (45.45%). Smoking was found to be the main risk factor in 86.36% patients. The most frequent symptom was cough (71.90%). The most common radiological presentation was mass lesion (51.65%). The most common histopathological type was squamous cell carcinoma (SCC) (38.02%) followed by adenocarcinoma (29.75%) and small cell lung carcinoma (SCLC) (16.53%). The majority patients (81.82%) were diagnosed in the later stages of the disease (III B and IV).
