One of my nannies has a larger-than-golf-ball sized lump below her left ear, sort of in the jawbone area. I finally got a quick feel of it today and it felt fairly solid. She seems unaffected in all other ways -- eating well, generally being herself. I first noticed it just a couple of days ago; don't know how long it's really been there, but I think it has grown just since I noticed it. (Yuck.) Every heard of this??
