Swollen groin lymph node

9 Jan 2021 16:01


I am after some advice from anyone who has been in a similar situation. I went to the doctors in December with a lump in my groin. She sent me for bloods and chest xray, which came back fine. I went for ultrasound on Christmas eve and showed lymph node to be 5cm in diameter, round, heterogeneous and increased vascularity stating it was suspicious of been malignant. I was referred to specialist and had CT scan with contrast on 7th Jan and I am awaiting a date for a biopsy. My question is, has anyone else had a lymph node this big and it turned out to be nothing. I've had it for a while I don't know how long but noticed it more a few months ago. Lymphoma has been mentioned. I said to the specialist it could be nothing and his response was a lymph node that big, is normally not nothing. 

Thanks in advance

Thank you Ben. I have my biopsy on Wednesday 13th Jan, just feeling a bit anxious about things and also with covid as, I don't want to put myself at risk of catching that incase it delays anything. I work for nhs myself. My specialist has advised I isolate until the biopsy, which I am, but work will expect me back after that. I am happy to go back if it was nothing but concerned if it is and I need treatment.

I hope your biopsy went ok today.  5cm is pretty big, and well worth checking out, I had a 73mm tumour in my groin (by the time it was removed) and it was seriously uncomfortable.  It grew incredibly fast once it had got started.

I had surgery, chemo and radiotherapy at what was then the height of the pandemic, and my doctors were far more concerned about getting the treatment done than worrying about the virus.  I don't want to downplay the seriousness of covid, as it's clearly running riot at the moment.  But I took the tumours far more seriously!

Good luck with everything.

Hi Jon

I hope you are ok. I am sorry to hear about what you have been through but glad you are getting the treatment you need.  I feel like I am on a rollercoaster of emotions at the moment. My biopsy got cancelled, as they had the results from the CT scan which stated it wasn't a swollen lymph node and a mass of 5.5cm by 5cm by 4.5cm, stating it was an obturator hernia and that I would be referred to the surgeons. Then a day later, today, I got a phone call from the cancer specialist stating that the surgeons say it is not a hernia after looking at the CT and the cancer specialist is taking back over my care and sending me for an urgent MRI scan. Can I ask, was your mass in your lymph node or not? The ultrasound scan I had said it was a lymph node, the person who has reviewed the CT scan stated it is not a swollen lymph node,just a mass then stating a hernia, which surgeons are saying it is not. How can they not know ?

Oh wow, that's not good at all.

So, lymph nodes are usually really small.  Only a few mm across.  They can grow when they're dealing with an infection etc and they'll shrink back again when things are back to normal.

I had a primary tumour in the head of my penis (turned out to be trapped in the foreskin), and some bits broke off and went to the first lymph nodes in the chain, each side of my groin.

In my right groin was the big 73mm mass.  That started as a couple of cancerous cells in one lymph node, then kept growing until it burst the node it was in.  Then it began to spread outside it.  The doctors call that extracapsular spread.  None of the other inguinal nodes in my groin had any disease in them.

They took all the inguinal nodes out of my left groin too, but there were only a couple of cancerous cells that side in a single node.  It was intracapsular, or contained within a lymph node.

It might just be a difference of opinion between different types of doctors, rather than pure incompetence.  They wont know for sure really until they've got a sample and can send it off to a pathology lab.  So it could be all kinds of things, but they need to check regardless.

The important thing is that they're taking it seriously now, and you can get a real idea of the facts.  The MRI scan will give them a better idea of what's going on, and you'll have a chest, abdomen and pelvis scan so they can look at the whole lymphatic system.

You might have a few other tests done too.  I write about all my adventures with cancer at if you're interested in all the kinds of things that go on in our hospitals!


Best of luck with the MRI, and try not to let the anxiety take over - it really could be all kinds of things
