Honestly I wouldn't wait see if you can get them at least to schedule the chest ct for you now The nodule could be anything but move on it quickly regardless. If you haven't had radiation or chemo there is always the potential for microscopic cancer left in the nodes - once its there it can spread. Even if it shaves just a few days off your wait time it's worth it to call and have them set up the next scan. - going to see the dr is great but he'll likely have you in go over the findings and have them schedule a ct anyway - get the jump on the process. If its not met sthen great less time worrying if it is you've save yourself some time and a wait ps cts results are usually available in 2 hes.
