At what age do you stop LDCT chest for lung cancer screening?

One of Medicine's three priority-ordered duties is to postpone death. This also pertains to persons who have reached age 81. Lung cancer can occur longer than 15 years after cessation of smoking. Even if surgery can't be done, primary radiation of Stage 1 squamous cell lung carcinoma can result in prolonged survival. LDCT means low-dose CT, and if the patient is willing to be screened, that patient is willing to take the very low risk of radiation-induced tumor.

I do not believe that there should be an upper age limit for lung cancer screening. We all have very active octogenarians and nonagenarians in our practice. This should be a decision between the patient and their doctor. Also, there should not be an exclusion if you stopped smoking after 15 years. The risk for lung cancer still exists, albeit lower yet still higher than a never-smoker.
