Get him into the doctor. My youngest daughter had one under her ear. It turned out that a lymph node was fighting an infection - not severe enough to need antibiotics but we did need to do a steroid cream to help with the near by rash that was causing the swelling. He checked all the other lymph nodes and none were swelled up. I don't remember him checking that location though. I had talked to a co-worker, who is also a cancer survivor, and he suggested getting her in. If nothing else, it will calm your nerves and make you feel better. It's probably nothing. One thing I did learn - if it hurts when you press on it then it's likely not in the cancer family (cancer apparently doesn't hurt to press on it). However, it could be something minor that still needs attention. Just so you also know, two months later the lymph node has returned to normal size and can barely be felt. She's still the happy 3 1/2 year old and never missed a beat (although I'm sure I did).
