Pulmanry nodules - 1272242

I am currently undergoing tests for lung cancer. I wonder if you might explain in layman terms the meanings and significance of the results from my ct scan. I had the scan after a 1.4 x 1.2 nodule was found on a chest x-ray. The ct scan also demonstrated a 4.1 x 4 cm aortic aneurysm in the ascending aorta. Here are the items for which I'd like simple explanations:

1.4 x 1.2 cm lobular nodule within the lingual with focally irregular margins at its anterolateral aspect and a punctate eccentric calcification. Discoid adjacent lingular ground-glass atelectasis is present

5 mm pleural-based nodule at the level of the lingula

No central endobronchial lesion

Precarirnal lymph node measures 1.3 x .7 cm

I am a lifetime non-smoker and have never worked/lived around secondary cigarette smoke. I was a medic in Vietnam in a region where agent orange was dispersed. To my knowledge I never was directly exposed, but may have had contact with soldiers who had agent orange on the uniforms.

Thanks, Mike
