Head and neck squamous cell carcinoma (HNSCC) represents a significant public health burden in Bangladesh with a high incidence and mortality rate. While traditional risk factors like tobacco and betel nut chewing contribute to HNSCC incidence, the emergence of HPV-associated HNSCC presents a unique challenge. The main goal of this observational study is to explore the prevalence, risk factors, and biological mechanisms underlying food habits and HPV-driven HNSCC in the population and identify the genomic changes and characteristics related to this malignancy. This study will provide the prevalence of HPV-associated HNSCC and screening the HPV typing in the Bangladeshi population, identify risk factors, and any biologically driven mechanisms causing HNSCC.
