Hi Denzie, Thank you so much for your reply! It is helpful to know that they are common and that yours have remained unchanged for 14 years! I have been learning that they are difficult to biopsy and just starting to hear more about new blood biomarker tests (liquid biopsy) that can help distinguish whether or not they are malignant. Have you heard anything about these tests? There is alot of literature that states true GGNs are often over treated and a watchful wait approach is wiser. I just discovered last week I have four GGNs and am only at the beginning of this "nodule surveillance" journey. I'm struggling to think of anything else at this point and mentally this has really affected my life, my outlook, anxiety level, fear of the future, etc. How do you cope with that? Any insight on that issue from you or anyone else who's been dealing with this alot longer than me would be greatly appreciated. I've thought about starting a new post on that issue! Thanks again for your reply. It helps just to have others to talk to about this... The club no one really wants to be in. 🙂 Wishing you good health!
