Can this be possibly ok?

My dear one has Stage 4 her2+ breast cancer spread to lymph and liver, and is more than half-way thru 26 weeks of chemo (herceptin, pertuzumab, Taxotere, carboplatin) with breast and liver areas shrinking encouragingly. but today the most recent CT scan results show six spots in the lung. Oncologist won't rule out infection or inflammation, and scheduled a PET scan and 2nd radiology opinion. Has anyone else had similar problems? Any encouraging words for us? Thanks!
