Lung cancer is a disease in which abnormal cells grow uncontrollably in the lungs, affecting their ability to function properly. It is one of the most common cancers and is often linked to smoking, though non-smokers can also develop it. Early detection through timely screening and advanced treatment significantly improves outcomes. Depending on the stage and type of cancer, treatment options may include minimally invasive surgery, robotic surgery, chemotherapy, immunotherapy, targeted therapy, or radiation therapy.
