HELP - PET/SCAN Result (is it cancer?)

Hello - I am scheduled for mitral value repair surgery in July and my cardiac surgeon ordered a neck-waist CT-Scan as part of pre-surgery evaluation. The CT-Scan showed enlarged hilar and mediastinal lymph nodes. My surgeon passed me on to pulmonologist who suggested a PET Scan, which was conducted today. I just got the results and did some online research myself, but am very anxious. I am meeting the pulmonologist Tuesday (5 days) but am very anxious and would love to know a bit more about the results beforehand. My wife was diagnosed with cervical cancer this year but is now cancer free after a succesful hysterectomy - but needless to say we are both very anxious and nervous. I dont have any symptoms outside of mild shortness of breath, more so tired quicker than anything major. For example, I dont have any issues walking up stairs or doing normal exercise (golf). My cardiac surgeon told me those symptoms are from my mitral value prolapse / regurgitation.

Anyway, the findings from my PET Scan are below ... any help is appreciated.

FINDINGS:

Mediastinal blood pool: max SUV 1.7
Liver: max SUV 2.1

HEAD AND NECK: Symmetrical nasal pharyngeal and oropharyngeal uptake likely
inflammatory. No hypermetabolic lymphadenopathy..

Postsurgical changes left mastoid with opacification of some remaining
mastoid air cells.

THORAX: There are multiple hypermetabolic mediastinal and hilar lymph nodes
for example: Conglomerate aorticopulmonary window 1.8 x 1.0 cm SUV max 8.7,
right hilum approximately 1.3 x 2.3 cm SUV max 9.7, left hilum 1 normal 4
cm SUV max 8.5.

There is hypermetabolic left upper lobe lung nodule 0.6 x 0.3 cm SUV max
2.8. This was not imaged on prior CTs.

There is a non-FDG avid left posterior lower lobe opacity which was present
3/28/2019 possible scarring or rounded atelectasis. Slightly different
appearance may be technical. Follow-up could be obtained.

ABDOMEN AND PELVIS: Normal physiologic FDG uptake.

MUSCULOSKELETAL: Normal physiologic FDG uptake.

IMPRESSION:

1. Multiple hypermetabolic mediastinal and hilar lymph nodes nonspecific,
inflammatory or malignancy. The relative symmetrical distribution can often
be seen in inflammatory conditions such as sarcoidosis. Consider tissue
sampling.
2. Hypermetabolic right upper lobe nodule versus intrapulmonary lymph node.
Close follow up.
