    Introduction
    

    Lung cancer is the second most prevalent cancer in women in Bangladesh and is the leading cause of death. Studies have shown that the prevalence of smoking in women in Bangladesh is decreasing, however the incidence of lung cancer is increasing. To this day patient characteristics of lung cancer in women have not been completely delineated. This utter lack of information makes it challenging to identify women at risk and provide optimal education and tailor screening programs. We examined the socioeconomic status and characteristics of women with new diagnosis of lung cancer at a tertiary care center in Dhaka, Bangladesh.

    Methods
    

    This was a descriptive observational study using a database of women with cancer who were treated at the medical oncology department of National Institute of Cancer Research and Hospital (NICRH) from January 2018 to December 2019. Data collected included demographics, exposure to tobacco products, and clinicopathological details. Confidentiality was assured and anonymity maintained. Data collection was performed in adherence to institutional guidelines.

    Results
    

    Amongst the 4423 women registered in the cancer database, 515 had lung cancer (11.73%). It was the 4^th prevalent cancer after breast (40.24%), gastrointestinal tract (24.32%) and gynecological cancers (13.39%). 82.07% were non-small cell lung cancer (NSCLC), 6.43% were small cell carcinoma, and 11.50% were other histologies including some mixed types. Of the NSCLC patients, 55.56% were adenocarcinoma and 26.51% were squamous cell carcinoma. The average age of the patients was 54.28 years and of those, 16.27% of patients were ≤ 40 years old. 34.17% of the patients denied tobacco use; 23.50% were cigarette smokers; 59.81% used betel nut and chewed tobacco, and 32.15% used more than one form of tobacco. Majority (80.4%) of the patients belonged to very low socio-economic status with mean monthly familial income of less than $120.

    Conclusion
    

    Unlike in other countries, only 55% of the NSCLC patients had pure adenocarcinoma histology. While less than a quarter of the female population were smokers, 59.81% endorsed using betel nut and smokeless tobacco. Other factors, which were not evaluated in this study such as using firewood, straw or dung as heat sources for cooking and second-hand smoking could contribute to high incidence of lung cancer in Bangladeshi women and these factors should be evaluated in a prospective setting. Understanding risk factors will help prioritize prevention and early screening efforts.
