Welcome Robinmarie. Stay off Dr Google, and let your doctors handle this, and come here to ask questions, and for support. You did the right thing going to the doctor. No scan can prove cancer, only a biopsy can. The next step after the scan results should be a biopsy, maybe a FNAB, Fine Needle Aspirational Biopsy, which is a quick, fairly painless procedure, to get a small sample of tissue from the lymph node under ultrasound guidance, usually by a pathologist, but some ENT's do it too. They are highly accurate when a proper sample is taken by anexperienced doctor. The pathologist can look at the sample under a microscope, and may be able to see if its cancer right there, but always sends it out for further histology, confirmation. Some doctors may want to do a surgical biopsy during an endoscope, triple scope. under general anesthesia, and proceed from there, if necessary.

It does seem suspicious, but there are other things that can cause similar symptoms, showing on scans like an infection, abscess, inflammation, to include the lymphs, which is basically the bodies sewer system, and gets clogged. No scan is 100 percent accurate. Is your doctor an ENT, who has experience with cancer? Depending on the results, you'll see what the next step is, and Florida is not short of excellent hospitals and doctors, if ever needed.

Waiting is the worst! Keep busy, and time will pass by quicker, so it seems. Good luck.
