GuitarGirl,
Sorry it took this long to get back to you. I had a long day. Let me start with the "Impression" since that is what they will wok on.

This part is pretty plain,
"Postsurgical changes in the right lung without evidence of local tumor recurrence."

"New left upper lobe nodular opacity and bilateral patchy groundglass lung opacities. These findings may represent infection/inflammation but a CT follow-up is advised to document stability/resolution." The right lung has 3 lobes; upper, middle and lower lobes. The left lung only has 2; the upper and lower lobes. "Nodular opacity" means a round shadow, while "patchy groundglass lung opacities" means a couple of areas of concentrated, small shadows that may or may not be cancerous. 6 of 7 of my CT scans have noted them and they all went away, meaning they were infections, rather than malignancy. This is what your doctor is hoping for. The "new 4mm nodular opacity" may or may not be cancerous. Nodules are present in the majority of CT scans, but turn out not to be cancerous. They'll wait and see if it appears more solid or grows in size on your next CT. Even if it grows a little, they may not elect to recommend treatment right away.

"Stable left apical groundglass nodules that may represent focal fibrosis, atypical adenomatous hyperplasia or adenocarcinoma in situ." Refers to the "Stable left apical groundglass nodules (images 22 and 24, series 11) measuring 8 mm" mentioned in the "Findings" section. "Apical means the top of the left, upper lobe. "Focal fibrosis" may be the beginning of pulmonary fibrosis, though it says yours is stable or unchanged from the previous CT scan. Fibrosis is caused by something you inhaled, which causes the tissue to harden and become unusable. "Atypical adenomatous hyperplasia" is a precursor lesion to invasive (malignant) adenocarcinoma which is what you had resected from your right lung. "Adenocarcinoma in situ" is a condition in which abnormal cells are found in the glandular tissue, which lines certain internal organs and makes and releases substances in the body, such as mucus, digestive juices, and other fluids. It is usually slow growing and can turn into malignancy. If the lesion starts to grow, they may decide to treat it.

"Stable small right pleural effusion". Pleural effusion is a buildup of liquid between the lining of the lung and the chest cavity. Evidently it was present in the same amount on the previous CT as well. It may not be easily accessible to get a biopsy, so they will wait and see on it as well.

So, it looks like you have to wait and see how your next CT scan looks.
I doubt all this helps much and hate that you have to wait. We all know how nerve racking that is.

Stay positive!
Tony

I would definitely have a problem with the nurse yelling at me.
Alot of times the PA comes in before the Dr. I always ask all my questions.

Guitar girl,
Find a new oncologist, preferably at a néw cancer center

After you read enough of them, you will get to be an expert on reading them too.
Just keep reading and learning about the anatomy of our pulmonary system. You can do it.

I know we're not supposed to Google information but I do. It has helped me understand so much about my cancer diagnosis.
