Lung cancer screening of active or former heavy smokers with yearly low-dose CT allows for earlier diagnosis and better lung cancer survival. Risk of developing lung cancer is higher among family members and close contacts of lung cancer patients, because of shared genetics, environment and life habits like smoking. The investigators want to engage lung cancer patients to refer their family members and close contacts for lung cancer screening, and evaluate if this referred population have higher risk of lung cancer than the population referred by their family doctors.

Mean number of referrals for lung cancer screening per participants
Mean number of referrals for lung cancer screening per participants: lung cancer participants will refer contacts directly on the REDCap questionnaire at enrollment. They will be contacted a second time 2 weeks after enrollment and asked if they referred additional people in their entourage for lung cancer screening.
Time frame: 2 weeks post inclusion
Mean PLCOm2012 risk prediction model score among referred participants
Mean risk of developing lung cancer in the next 6 years using the validated PLCOm2012 risk prediction model in smokers or ex-smokers referred participants that are 55 to 74 years old.
