My Mom PET scan results came out today. Good news is that except the afflicted lymph node in the neck, everything else is clear. Chest XRAY and ECG results are all good.

Surgery is scheduled for Oct 31, doctors mentioned that they will do partial glossectomy and remove lymph nodes upto Level 5. Based on the pathology results after surgery, they mentioned that they could advise radiation (nt sure how this is possible)

Thanks everyone for your help and support!
