Hi all. I'm a 35M going in for an axillary lymph node biopsy on an enlarged node I've had for ~18 months. I've had three ultrasounds - one inconclusive and the other two not suggestive of anything untoward, but my specialist wants to draw a line under it by doing the biospy as it is quite large/firm and hasn't gone down. No other concerning symptoms (weight loss/night sweats/fatigue).

I was wondering if there is any risk of lymphedema or long term swelling occuring from a biopsy of a single node? I was told they're not removing the node entirely but taking a majority of it for the sample. The reason I am concerned is because I have already been having a lot of water retention/swelling for a few years in my upper chest/armpits/trunk and sometimes in my ankles too.

Thanks in advance for any replies :) Kristian
