Please get an appointment with a pulmonologist as he/she will recommend a bronchoscopy or not. I think 8mm may be too small for biopsies, bronchoscopies so like many of us you are in the 3 month CT scan let's wait program. The nodule is currently being monitored, thank heavens and likely those tests will need to be done when it increases.

Hi JS (@jstarkman). Remember that you posted this question on the Lung Cancer group, so you are seeing responses from people with cancerous nodules. Most nodules are not cancerous. The final pathology has come back for my latest nodule and it is fungal, not cancer.
Having a bronchoscopy does come with risks, and the pulmonologist will be able to help answer any specific questions that you may have. The location of the nodule can make it fairly easy or extremely difficult to biopsy via a bronchoscopy. My original nodules were deep in the lung, and were never biopsied via bronchoscopy, but this recent nodule was barely inside the lung so it was easily accessible. A rescan in three months doesn't seem unreasonable to me, but a pulmonology consult never hurts.
