Lung cancer (LC) is the leading cause of cancer-related deaths globally, with about 1.76 million deaths in 2018. Smoking is the main risk factor, along with genetic predisposition and asbestos exposure. Primary LC starts in the lung tissue, while secondary LC spreads from other body parts to the lungs. LC is often classified into small cell and non-small cell types, which affects treatment plans. For non-small cell LC, surgical removal is the first option. Advanced cases might be treated with chemotherapy, radiotherapy, or combinations, but complete remission is rare. Minimally invasive treatments like microwave ablation (MWA), radiofrequency ablation (RFA), and cryoablation are used for local tumor control, especially in patients who can't undergo surgery. These methods help preserve lung function and improve quality of life. New techniques like Cyber-knife and Gamma knife are also emerging as alternatives to traditional ablation methods.
