@scoop2365- Hi Scoop-- You aren't alone and you have every reason to be frightened. Being told that there was something picked up on a CT scan is pretty darn scary. I am a mentor for Mayo Clinic's Connect Lung cancer and disease groups and I welcome you.
Your wife's nodules are small. They are respectfully about 1/2" and the larger one just a bit over 1 ". Did they tell you if they were in the same lobe or not? You have three in your right lung and two in your left. Each lobe can be taken out, if necessary, leaving plenty of lung tissue for a full life.
I am a 22 yr lung cancer survivor. I actually go for a follow-up CT scan tomorrow. And I'm nervous, even after all this time.
There are several things that you might anticipate. First list any and all questions that you might have down and make sure that they are answered. You both have the right to know everything about your wife's condition.
I know that you know very little right now because it will depend on what her lesions are but I'm sure that you will have a million questions buzzing around. Right now try not to get too carried away with anticipation if possible. Try and keep busy, if your wife is able too.
Try and keep your chins up. So far the only thing that you know is that there are lesions, not that they are cancerous. When is her next appointment?
