“How often should you get a lung CT scan?”
I am a 28 year old male. I want to know how often should you get a lung CT scan?

A CT scan emits radiation like an X-ray. So- it’s important to perform a CT for a specific reason.
Never unless you have a known underlying condition that needs it. Screening CT of the chest is only indicated in people age 50-80 with a 20 pack year history, currently smoke or have quit within the last 15 years. Those people get yearly screening.

It depends on reason. Once is usually enough for most symptoms but you have to be careful about frequent lung CT scans as there is radiation involved and multiple CT scans can be harmful over long haul.
Unless there is a medical indication, you should not get a CT.
