Can the Lungs Really Recover From Too Many Years of Smoking?

Question by Carles A: Can the lungs really recover from too many years of smoking?
I don’t know how all the build up of tar and other poisons can be eliminated. Is there any medical data that suggests that the lungs can recover?. Do it really makes sense to stop smoking if the damage is irreversible. Lungs are not like bones, that can be can fixed.

Best answer:

Answer by ?USMCwife?
They never fully repair themselves but they do rebuild some of the damaged tissue ?

Answer by me
Not entirely, but if a smoker quits for a very long time (probably many years) then his/her lungs will start to heal, and eventually they will have the same risk of getting cancer or other disorders caused by smoking as a nonsmoker does.
