A pet scan will generally show 3 main groups of findings. Infection inflammation or cancer. With a history of breast cancer a biopsy may be considered but that will depend on the details of the situation.

Although clearly one has to be concerned about the possibility of metastatic breast cancer, there are many causes of "hot" subcarinal lymph nodes on pet scan. The only definitive way to evaluate the area would be with a biopsy or fine needle aspiration with pathological examination. Good luck.
