LDCT lung cancer screening is recommended for individuals aged 55 to 80 years who have smoked at least an average of 1 pack a day for 20 years (20 pack years). This also includes those who still smoke or have quit smoking within the past 15 years. Note that individuals with symptoms of lung cancer at the time of screening, such as unexplained weight loss, are not eligible.
Certain symptoms can be suggestive of lung conditions that should be evaluated and treated, if necessary, by a healthcare provider. These symptoms include fever, chest pain, a new or changing cough, shortness of breath, coughing up blood, or unexplained weight loss. Having any of these symptoms can affect the results of lung cancer screening and may actually delay potential treatment.
