Your chest CT confirms that you have mild COPD so you do need to stop smoking. The COPD will get worse each year that you continue to smoke . Your pulmonary function tests show excellent results however! So that is great news for you! 100 percent is normal so whatever measure that you had is better than average. Pulmonary function studies have many parameters though so I don't know which this represents. FEV 1 is a key measure but I don't know which parameter it is that was so excellent in your case....
How MUCH do you smoke? 1/2 pack per day vs 2 packs p e r day can make a huge difference .
The clubbing is a clinical sign. This probably has to do with the rapid growing nail beds over time getting lower oxygen. You also poison your system with carbon monoxide with smoking which locks out about ten percent of your red cell/ hemoglobin function. So even with maintaining good lung function you do deprive your system of adequate oxygen.
Lifetime risk of lung cancer of smoker is about 10 percent.For non smoker is about 1 percent. So to quit does help reduce your risk in this,regard.

At your age lung cancer is still very low risk --Yes to that ...
Being sedentary would impact certain aspects of your general health but not so much your risk of potential development of lung cancer. The main thing to reduce risk is for you to stop smoking. ..
Diet being healthy is also good for your general health ...plenty if fruits and vegetables ...the more antioxidants that you eat with diet and certain supplements may be helpful to reduce risk (supplement CoQ10 is excellent antioxidant )
The wheezing is caused by inflammation of small airways. When airways swell with inflammation then the thin open tubes of airways become thicker walled and less open airway passage ...so especially breathing out you may wheeze through tight airways ...it is like comparing a large straw to say a coffee stirrer ....
Overall health would benefit from healthy lifestyle habits across the board--- stop smoking -- more activity /exercise / healthy diet (lower saturated fats , generous for fresh fruits and vegetables )
The smoking leads to changes of the lungs and airways and neutralized about ten percent of hemoglobin and this reduces the effective oxygen transport to your body but diet would not directly affect this so much ...

The changes of COPD which is associated with your smoking may improve to a degree with stopping. The airway inflammation may reduce to a degree. The airways rebuild defenses to help reduce your risk of infection. Changes of COPD are in past reversible but to much extent there are irreversible changes. You may have thickened walls of small airways that can't get back to normal. You could have scattered area of damage to airsack units (alveoli) that would not be reversible.
If you have wheezing then treatment with bronchodilator inhalers may help. Similar with shortness of breath.
You do benefit from stopping smoking and staying stopped. There is no way to restore health and function of your lungs when you were 18 however.
The arm pain would seem more likely to be musclar in nature. Your age would correspond to low risk of lung cancer. I think this would be unlikely explanation as to your arm discomfort....
I hope that this is helpful for you Let me know if you have further questions.Best regards,
The wheezing may improve after you quit smoking. It may improve with treatment of inhalers that are bronchidilators as well. Spiriva is most commonly used in COPD. ALBUTEROL is another commonly used bronchodilator. Smoking is going to cause changes to lungs regardless of your activity . Exercise benefits your pulmonary function.

You may be able to upload a picture directly to page ...see if your toolbar has paperclip icon...this may allow for attaching a file such as a photo...or you may upload to a site such as photobucket..com and then give me a reference to it

No clubbing if nails is NOT SPECIFIC to lung cancer . That sign usually just indicates pulmonary disease such as COPD...It is not a sign to indicate lung cancer ...
I hope that this is helpful.Best regards,
Well wheezing is from the lungs. You might perceive the sound in different ways possible or you might be describing a different type sound. When we refer to wheezing we refer specifically to a sound of airway obstruction in your lungs however. Wheezing may come and go . It is related to smoking and may potentially improve , yes ....
Well you can have upper respiratory NOISE certainly. You can have sinus or nasal passage congestion but such potential noise would not be what we would qualify as WHEEZING.Wheezing is a specif type of lung passage type noise associated with bronchiconstriction of small type always in the lungs. ( note even noise of different type of larger airways is referred to as rhonchi) so WHEEZING per se is a very set definition.
I hope that this helps and makes sense. Let me know if you have further questions.I will be happy to get back with you.Please remember to leave positive feedback.Thank you and Best Regards,
