What is the life expectancy of a patient with mild emphysema that just quit smoking? -
it depends on how old you are, and on any other underlying medical problems, and how well you manage whats left of your lungs....if done properly, the life expectancy can be a long one......if not it can be abruptly shortened....so no to smoking, and stay away from others that smoke...
I asked a similar question to my doctor little while ago, doc said it is promising if the patient should quit smoking and do a series of curing process provided by medical professionals.
Make sure he/she quits smoking. Good luck!
