@godfather2- I'm not sure of the answer. I have what is called Multifocal adenocarcinoma of the lung. All my lesions begin as GGO. Some become cancerous and they grow, others don't - As you know I'm not a scientist. My kind of cancer is very slow-growing. This is called an indolent type of cancer. I consider it a type of chronic cancer that I just have to live with.
But not all are cancers.

Your questions are great and I advise you to write them down and bring your list with you to your appointment.

Also, your next CT scan will give more information and a biopsy too if that is advised. I know that this is all very upsetting and there must be a million things going through your mind, including a lot of worries. If I were you I would take each term that was in your report and google it. Information is power and the more information that you can garner the better. I found this particularly helpful when making decisions.

DO you already have a list of questions? What else would you include?
