Lump on baby's back

5 replies

Just looking for advice if anyone has been through this and what was the outcome as I am going out of my mind with worry and guilt aswell. Sorry it's all a bit long winded and rambly.

My baby is 4 months old and has a lump on their back about the size of a 2p/few cms but it's disc like rather than like a golf ball, for about 2 months now beside their spine.

I showed our HV at the time who said to keep an eye on size/any changes and to see GP if concerned. The lump is still there although no changes so I spoke to GP this week who wanted to see baby and have a look. Upon examining GP said it could be a number of things but she would refer to paeds and for an ultrasound to rule anything out given their age and it was on the right side.
She said she'd do an urgent referral. My family said that GPs will usually always refer to hospital anyway for small babies.

She had mentioned lipomas and benign cysts etc. I couldn't take it all in because as I was worked up at the thought of him going to hospital.

Of course against all advice in life, I've been googling and all the doomsday scenarios come however, when you Google it brings up info about Spina Bifida but also the fact that it's close to the spine should be red flagged. I didn't hear the GP mention spina bifida but it's basically the main result on Google.

I have been tears all day because I didn't take them to the GP sooner and get it checked out. I'm devastated I've put their health at risk. I'm a FTM and assumed (obviously naively) it was OK as our HV never directly said to yes, get it checked. I've followed my gut instinct, but too late.

My family have said not to blame myself as wouldn't change anything but all I can think is if it was cancer (god forbid) that yes it can as I've delayed treatment. All I want is for baby to be okay.

Definitely do not google and go not blame yourself. You did exactly the right thing by flagging it to the HV and you followed their advice. You baby is now being seen and you will get an answer; hopefully it is nothing but they are doing all the safe checks to prove that it is nothing to worry about. Take care 💐

Honestly it could be anything, and way more likely to be nothing at all. Good luck but dont google any longer, you’ll just fall into a black hole of scary rubbish

Thank you both so much for your kind words. They have helped.

Hopefully we are seen quick and it's nothing like so many things are.

I asked my husband last night did he not Google it and he said of course he did and that he'd read all the different things too. He said there was no point getting worked up over something that could be nothing but if it is something we can and will get through it. I wish I had his way of looking at things.

spina bifida would be in the midline, and present since birth. As this appeared a bit later, one possibility is one of the weird raised birthmarks that only show up after a few weeks. Is there any colour to the lump? As that would push in the direction of birthmark. Ultrasound is usually pretty good for funny lumps, so here’s hoping you get reassurance soon.

Thanks for this. It is spine adjacent - like right beside it.
I'm not sure if that makes any difference? If I run my finger down the spine I don't think you can feel it, but was concerned it could affect the spine as they grow or if it grew. Nothing was ever mentioned during pregnancy, at birth, nor on the GP check up at 6 weeks. It does seem to have appeared from nowhere and at that size, although I assume it has obviously grown to that size subtly.

No colour/texture etc. My dad had mentioned the birthmark thing too and my niece has one of those on a different part of the body, although hers is much much larger but also skin coloured.

Hoping the ulstrasound referral is through quickly, it's the waiting and not knowing that is the hard part. I will try and remember to update when we find out more.
