My 16 year old daughter has a hard lump behind her ear. Noticed it about 3/4 weeks ago. No virus or illness that would explain it. She thinks it’s reduced but I can still see it. She is a bit triggered by it as my husband was diagnosed with throat cancer 2 years ago and his only symptom he had was an enlarged lymph node in his neck. She won’t let me look at it and is reluctant to go to the drs but I have made an appointment for her next week but haven’t told her yet. Does it look like a lymph node or a cyst? I’m trying not to panic but I hoped it would go by now if it’s a lymph node. Any positive stories please
