A snapshot of lung cancer: where are we now?-a narrative review.

LC remains the leading cause of cancer-related deaths globally with poor prognosis despite available treatment options and even recent advances in both diagnostic tools and management guidelines. Human nuclear and mitochondrial alterations clearly play a role in tumorigenesis and progressive genomic evolution is crucial in the early carcinogenesis of LC which is strongly influenced by host immune surveillance. It is imperative that more research and clinical trials be undertaken to appreciate an in-depth understanding of LC from the molecular level to facilitate the discovery of more targeted therapy and overall better management of LC.
