Are "Radio-opacities" concerning?

[troubledsoul]

I received this note along with the provided xray: "eval and tx #17, 32 area radio-opacities noted on the angle of mandible in both areas". My general dentist referred me elsewhere and it's taking forever to hear back from them. He also mentioned they would possibly take a biopsy to check if cancerous. Based on what's circled, are those area lymph nodes? That's what I am really worried about because as you may know that's not a good thing. Please provide any assistance /knowledge you have.
