Saudi lung cancer prevention and screening guidelines

L cancer is the number one cancer killer worldwide. Unlike other major cancers, lung cancer has a unique feature which is a known risk factor for majority of the cases. In the United States, cigarette smoking is linked to about 80%–90% of all lung cancers. This knowledge represents a great opportunity to prevent the majority of lung cancers by tobacco control. On the other hand, knowing the majority cause enables us to identify patients at risk to implement early detection and screening interventions. These facts were translated into clear standard of care and practice guidelines in developing countries. In the United States, lung cancer screening guidelines are now evidence based and becoming the standard of care for high‐risk population based on the National Lung Screening Trial and other studies. However, it is critical to have these guidelines be adapted to the particular setting.
