All- I have found the following links to help us maybe understand a bit more about our disease, multifocal adenocarcinoma of the lung. It's overwhelming, scary and very hard to understand. And there are few answers, with lots of questions. Right now researchers are trying to figure out if the nodules are little metastases or primaries, along with a million other things. I have several. Some might be cancerous, but are too small to biopsy or treat. Some come and then go. Some grow and then shrink. An oncologist once told me that my lungs loved to grow things. "Thanks"
Whatever this disease is the one thing it does do is test out patience. It's a sort of lifelong haze of wondering- do I or don't I have cancers growing in my lungs, and how many? Can they be removed or zapped or chemically killed?
I can only relate my story and give out suggestions. I'm not a doctor and can not give medical advice.
