This is what 11/2014 pet about lung said:

Ground-glass infiltrative process in the basilar segment of the right upper lobe, demonstrating minimal metabolic activity, with a maximum SU value of 3.18. � There is also some ground-glass infiltrative process in the left upper lobe. There is an area of consolidation - that may represent some consolidation, with slightly thick-walled cavity in superior portion � involving the posterior aspect of the lingula, abutting the major fissure. This measures approximatively 2 cm. There is 'also a 5 mm smoothly marginated nodule, apparently in the right middle lobe near the confluence of the major and minor fissure. There is a calcified granuloma in the lateral aspect of'the right upper lobe. There are some small nodes demonstrated in the AP � window and anterior carinal region.

This is what the new April 2015 PET scan actually said about lungs:

The ground-glass previously described in the anterior aspect of the right upper lobe has now consolidated into an 11 mm nodule. This Nodule has only very mild metabolic activity maximum SUV of 1.82. The evolution of this density is suggestive of low-grade adenocarcinoma in situ.

Right upper lobe lesion has evolved into a nodular density, this very likely represents a low-grade neoplasm. Follow-up examination is recommended in four months by CT.

I recently saw my chemo oncologist who said I was the big discussion at cancer conference. I don't know what that meant. She also said they all came to look at the scan and asked what radiation Dr had told me. I said he said it was in a bad spot and he didn't think it was anything.

But now that I have read PET I am conflicted. Should I seek a second opinion or just wait?
