hi @crisatl - I can understand not wanting to delve into another major surgery. I think it's wise to do your PET scan as planned and that will give you more insight into the likelihood that the nodule is malignant. The rule of thumb is that the bigger the nodule is, the higher chance it's cancer. Perhaps a liquid biopsy would also be a less invasive option for you? I have multifocal lung cancer, so I can't treat it with surgery. But my aunt just had a lobectomy a couple months ago and she's feeling great (better than before surgery bc the tumor was causing other symptoms like high blood pressure.) I would encourage you to keep all of the treatment options on the table, until you can say for sure that it's not cancer.
