Enlarged mediastinal lymph nodes - 1268780

Had bronchitis for about a month or so leading up to my most recent CT. Was told by surgeon they found about 6 enlarged mediastinal lymph nodes R2 and R4.

I had stage 2 nsclc - adeno diagnosed in Dec 2013 with lobectomy of my lower right lobe. 3 nodes close to the tumour were positive but removed with the lobectomy. I had adjuvent chemo. Scan last August was all good.

I am hoping the enlarged nodes are due to the bronchitis/lung infection but it seems everything I read conflicts. Lots of sites say swelling from infections is usually above the clavical or in the armpits or groin. I would think that swelling of any node could be from an infection. That is my hope.

My question is would it be common or a very fairly reliable to assume that the mediatstinal nodes could be enlarged from the lung infection ... or would that be a long shot?

I have a biopsy on Tuesday so I guess I'll know more soon enough.

Thanks in advance for any advice or similar experience someone is willing to share.

Cheers,

Joanne
