How to screen for lung cancer?

Hello doctor,

I fear that I might have a lung infection, and I want to know about lung cancer screening as part of my commitment to proactive health management. Lung health is a priority for me, and I have some questions regarding the screening process, its effectiveness, and related considerations. Could you provide insights into the current recommendations for lung cancer screening? According to age or risk factors, who can undergo lung cancer screening? I am particularly interested in understanding the differences between imaging techniques like CT scans and other potential screening tools. How effective is lung cancer screening in detecting the disease at an early stage? Are there specific benefits associated with early detection, and how does it impact treatment outcomes? Kindly suggest.
