Lung cancer keeps taking lives, with nearly 1. 8 million deaths globally in 2022. This highlights the urgent need for better ways to detect and treat it. Long noncoding RNAs, known as lncRNAs, are vital for cellular functions. They influence how genes work and send signals in the body. Recently, scientists found that lncRNAs can go wrong in cancer, causing cells to behave abnormally. This can lead to lung cancer, especially types like Non-small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC). lncRNAs can be bad guys, promoting cancer, or good guys, stopping it, depending on the type of lung cancer. Understanding how lncRNAs work in these cancers can help improve diagnosis, treatment, and patient survival. Researchers are eager to use lncRNAs as tools to detect and treat cancer. The more we learn about lncRNAs, the clearer it becomes how important they are in lung cancer.
