Lung nodule: New lung masses found on imaging should be followed or biopsied. Many small lesions less than 1 cm in size are observed. If it is enlarging or is associated with symptoms such as cough, or coughing blood would be worrisome. Prior ct scans that show the mass previously would be reassuring. Risk factors for lung cancer such as smoking would raise suspicions. Speak with your md, yes to repeat ct.

From nothing: To an early something. The anxiety you are experiencing is given as a main reason to not do screening ct's in smokers. 3 mm is too small to worry about. If it were me, i'd re-ct in 6 months to a year to check change in size. You can google the nlst - national lung screening trial. Do you smoke? Time to stop if yes. Good luck.
