Many people die from lung cancer because it is diagnosed late, spreads to other parts of the body, and has a high treatment failure rate. Because they can be involved in either oncogenic or tumor-suppressing functions, LncRNAs are quickly becoming core molecules in lung cancer. Since LncRNAs are long-lasting in blood, they can be utilized as non-invasive diagnostic tools for cancer at an early stage. We review the latest research that has brought together evidence from real-world observations concerning the processes through which LncRNAs work in cancer formation, how they allow cancer to develop drug resistance, and how they can be used as possible diagnostic tools and markers of outcome, with a focus on lung cancer. We also cover some of the ongoing treatment strategies that can target LncRNAs.
