I noticed a hard bean sized lump under my skin beneath my ear lobe at jaw line in May 2017. It wouldn’t go away so they did an ultrasound last year that said it was a 1.5 inch lymph node. It never went away and seemed to be getting larger, slowly. I decided to go back to Dr and they did another ultrasound two weeks ago that showed an oblong hypoechoic 5mm short axis mass on my subglandibular gland. I am seeing an ENT next week. Could this be lymphoma?
