It is a very rare circumstance for an urgent biopsy of a one cm nodule, said to not be present 3 months ago. You would be wise to confirm with your pulmonologist what the radiologist means by “suspicious”, if he/she (the pulmonologist) agrees, and if the radiologist who reported the nodule to be suspicious had access to both CT Scans for side by side comparison. I would recommend that you not agree to a biopsy until you have had a chance to speak with your pulmonologist (assuming the biopsy is to be performed by a 3rd party.)
Good luck
I'm sorry it was oct 2013 not 2012. The new lesion has developed within a 3 month time
