To be honest we aren't sure yet. We've been tracking it for over 2 years. It hasn't grown much. The assumption is slow growing Adenocarcinoma. Discovered it in July of 2021. 2.6 cm solid with ground glass opacity around it. There are also multiple satellite nodules one of which grew from 6mm to 7mm over the 2 years we've been tracking. The large nodule has not changed in size but the density has increased. The pulmonologist started out not being concerned thinking it may only be scarring from my acid reflux. The last visit he seemed rather concerned. He told me "your 2024 is going to suck". He also added "but once you get through this there is a 90% chance you'll be in the clear". Hope is right about the 90% thing. Just today I got the biopsy scheduled for March 7th. CT guided needle biopsy. We will see from there. Thank you for sharing your story. It seems rather similar to mine so far. Did you need to go through any chemo or other treatment?
