swollen lymph node

[rubyroot]

Found a small lump on back of 15 week old babies neck, a less diligent neurotic parent probably wouldn't even have noticed.
Dr says lymph node asked if baby has had a cold and said lymph nodes only come up with infections. But, baby hasn't had a cold or temperature or infection (that I know of). It is a little bigger, but still not massive.
Dr is sending for scan just to make sure, she mentioned the c word! She did say likely to be nothing, but the seed has been planted.
Anyone had a similar experience? I am worried as no evidence of infection and only one lump- surely the one on other side of neck would come up too?

Does your baby have eczema? My daughter gets enlarged lymph nodes when her skin flares up badly.

No- has very mild cradle cap though. Also worried that it is only one node. I am probably worrying over nothing, much more likely to be something benign than lymphoma- but I've been googling

My ds has a lymph node that comes up and down. Also got it checked just in case but he is fine. For us it's like an indication when he's under the weather a little.

Thanks curly, that's good to know.
My baby is going through leap 4 so I'm hoping the more intense crying is to do with that. He does tend to stop once he gets the attention he is seeking.
