What could be the reason for the various nodules in the lungs?

Hello doctor,

I have been having sharp, stabbing pain in the chest (they feel like pain related to nerves as I get them all over the chest, sometimes on both sides at the same time) as well as shortness of breath and a stuffy nose, phlegm or sputum, sometimes cough and wheezing. Sometimes, I feel pain when I breathe, it is very sharp and I have to hold my breath or take shallow breaths. I had a computerized tomography (CT) scan done, and the results showed: a five millimeter (mm) subpleural nodule in the right lower lobe, three millimeter subpleural nodule in the lateral right middle lobe, and three millimeter peripheral lung nodule in the lateral left lower lobe. There are a couple of tiny subpleural nodules in the lingula. No, interstitial thickening, bronchiectasis or significant air trapping. My question is, will these nodules produce these symptoms at this stage? Are they likely benign? Also, does lung cancer usually spread out like this, or does it usually start in one spot and turns into a mass? I vaped heavily for about seven years. Thank you.
