A member asked:

Saw a 3 mm nodule during a ct scan at the base of my left lung. what could it be?

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.
