Hi @shellyrenee, Welcome to Connect. Sorry to hear that your nodules have changed that much in the past six months, but it's good that they found them at this early stage. I agree, if you've seen that much change over a six month time period, it's certainly time to take action. You may want to ask your surgeon if your samples will be sent for genetic/biomarker testing. As the results can impact any future treatment plans. None of your lymph nodes were lighting up on the PET scan, correct? Are all of the nodules isolated to the same lobe of the lung?
