Screening for lung cancer with low-dose computed tomography is indicated for which patient?

The recommendation for lung cancer screening with low-dose computed tomography (LDCT) is typically aimed at specific populations, particularly those with a significant history of smoking. The correct choice reflects the guidelines by emphasizing age, smoking history, and cessation period.

Individuals aged 50 to 80 who have a history of heavy smoking, defined as a minimum of 20 pack-years, are prime candidates for screening. In this scenario, the choice focuses on the 60-year-old individual who quit smoking 10 years ago. Even though this person is not currently smoking, they have a considerable smoking history (if they smoked heavily) and fall within the recommended age range for screening.

The other choices do not align with the recommended guidelines as closely. The 50-year-old current smoker might be close, depending on the smoking history specifics, but age can also consider accompanying risk factors. The 75-year-old who quit smoking 20 years ago and the 85-year-old current smoker are outside the typical screening age limit or have a longer cessation history which may deem them lower risk compared to those who are still within the defined screening criteria or have more recent smoking habits.

In summary, the correct answer focuses on the individual who meets the precise age parameters and has an impactful
