Lots and lots of Lung Nodules

gah

I posted this in the mets forum "not diagnosed but have questions" thread, but maybe it's better here...

This is my first post here, but the YSC forums (and Facebook) have such a small sample size, I wanted to take this question to a larger group.

I was dx at age 24 with a 2.4cm ER/PR+ Her2- lump in May 2010, and was treated with a bilateral mast with implant recon, AC-T chemo, and tamoxifen (which I still take). I am now 28. At my three year MRI to check on my implants (the first scan I've had since finishing treatment) "incidental note" was made of "multiple bilateral pulmonary nodules" and a CT was ordered to follow up. The CT also shows "numerous" bilateral nodules from 1-10 mm in size, the larger of which are "relatively more cranial in location" (i.e. they're more in my upper lung than lower lung, I guess), and have "multilobular" margins. I have an appointment with lung specialists on Friday, but I was hoping to hear from ladies who may have had similar findings. While one of my onc's nurses tried to convince me that mets doesn't show up as numerous smaller nodules, that isn't what I've seen in my Googling.

I also just started coughing, but I think I may be coughing and experiencing chest tightness due to the fact that I'm getting pretty anxious. That said, of COURSE I would develop a cough once I find out I have lung nodules. I also went to a spinning class yesterday and experienced cough and shortness of breath afterwards, which is pretty uncommon for me, but I also haven't worked out pretty much at all in the three weeks I've been dealing with this, because I'm afraid. So I guess it could just be decreased fitness combined with an intense exertion.

I recently traveled to Southeast Asia, and I live in the midwest of the US and am fairly "outdoorsy," so there is a chance this could be a weird fungal or inflammatory issue.

I'd love to hear from anyone who experienced something similar - whether it was mets or not. I'd like to become as informed as I can.
